Motion Control – Rotational Voice Coil Stage

Quickly and repeatably steer an optical beam with a diameter of up to 25 millimeters over 90° with 25 microradians of resolution!

RVC-9025 Rotational Voice Coil Stage: Up to 25mm wide mirror; Controllable positioning over +/-45 degree optical; 5 arcsec (25 microradians) optical position repeatability; 1 degree optical step-and-settle in less than 5ms; Fully integrated servo controller; USB 2.0 and auxilary user electrical interfaces; X 58 x 28 x 21 millimeters, 30 grams

Forestville, CA – The RVC-9025 Rotational Voice Coil Stage provides a means to quickly and accurately set an angular position. The frequency is factory adjusted to customer specifications during the manufacturing process. Amplitude of the resonating mirror can be adjusted through either an analog input voltage or the USB interface. An optional high-resolution position feedback sensor can be monitored by an analog output signal on the User Connector. The RS-25 Resonant Scanner can also be configured with a high-resolution 16-bit Analog to Digital Converter to quickly sample and report the mirror position at any moment if the position sensor is included.

The RVC-9025 Rotational Voice Coil Stage provides a means to quickly and repeatably steer an optical beam with a diameter of up to 25 millimeters over 90° with 25 microradians of resolution. The RS-25 Resonant Scanner is designed and optimized for applications that typically require a means to scan an optical beam. Using various patent pending features the RS-25 Resonant Scanner can run 24/7 forever without compromise. At the heart of this product is a pair of carefully designed flexures that mimic the spring in a classical spring-mass harmonic motion system. The mirror or other load acts as the mass and together a natural resonating frequency is borne that provides unparalled performance and reliability. A small motor is carefully coupled to the system to makeup for small system losses that would otherwise dampen the oscillation.

The Mirror: The mirror is an integral part of the RVC-9025 and is usually specified at time of order. The mirror and its associated inertia will largely predict the overall step and settle time of the actuator. With that in mind the user should careful consider parameters surrounding the mirror including its shape and flatness. The mirror should be no wider than absolutely necessary and sufficiently long to accommodate the beam elongation as a consequence of the tilting process. Mirror flatness will largely dictate its thickness and overall inertia. In special cases, mirror thickness and its affects on inertia can be managed using costlier materials such as beryllium that have a higher specific stiffness. As the mirror thickness grows, its front surface will proportionally move further off the rotational axis which in some cases can be undesirable. Other parameters including coating and scratch/dig need to be included to fully describe the mirror. While a mirror is probably the most common payload other customer supplied or specified loads can be used such as gratings.

Position Sensor: The RVC-9025 is able to position its mirror with a resolution of 25 micro-radians in a large part because of the high-resolution sensor it uses. The analog nature of its non-contact sensor also makes it noise limited by adjusting its bandwidth. Careful control and optimization of the sensor signal permits the servo to operate at a higher bandwidth and thereby having a higher stiffness and exceptionally low positioning wander or hysteresis.

Voice Coil Motor: The RVC-9025 includes a high efficiency voice coil motor–somtimes referred to as a single phase DC motor. The motor coil is directly coupled to the mirror support beam and position sensor. That tight and rigid coupling of the load, actuator and sensor assures exceptional position repeatability and step-and-settle times. The high efficency of the motor coil yields a small and light-weight coil that adds little of the overall motion inertia.

Integrated Electronics: The RVC-9025 includes a highly miniaturized servo amplifier and controller. The mirror position can be controlled through either the USB and its 16-bit DAC or an analog input signal. At the same time mirror position can be monitored from and analog output or the USB and an optional 16-bit ADC. The auxiliary input header also provides a means to enable the amplifier and monitor it for faults. Thereby supporting a configuration for a deeply embedded and autonomous device.

Motion Control – The World’s Most Compact 3000 W Integrated Servo Motor

November 26th, 2020

Editor-Publisher

Motion Control – Compact 3000 W Integrated Servo Motor

JVL presents a new AC Servo Motor with built-in controller, Nano-PLC and direct AC mains supply with same capacity and length as traditional servo motors

Vaughan, Ontario, Canada — Motion Control Components – JVL, the European leader in the development of integrated servo and stepper motor technology, has now again developed a new and unique product in the field of integrated motor control. JVL’s newest additions to their portfolio is a complete, high-capacity MAC motor® with rating of 3000W. MAC motor®s are complete servo systems including a high-dynamic AC servo motor, hall-sensors, encoder, power supply, driver and positioning controller and Nano-PLC, as well as facilities for incorporating various control modules such as Bluetooth, WLAN, ZigBee, EtherCAT, EtherNet/IP, CANopen, DeviceNet, Profibus, Profinet, Nano PLC, RS232/RS485/USB, Process Control, etc.

New Compact Motor

The MAC motor sets completely new standards for the performance and size of servo controls. With a length of only 311.8mm for a 3000W motor with a torque of 9.55/28.6Nm at 3000rpm, this MAC motor matches the size of traditional servo motors without built-in controllers with flange 130x130mm. This has only been possible through the use of extremely compact motors and the development of electronics and mechanics that utilise the latest technologies and manufacturing methods. So what about vibrations and temperature? As with the other integrated servo motors in the range (50-3000W), both the motor and all electronic components have been specifically selected to withstand the rigorous demands required by industrial use.

Power Supply and Energy Savings

Powering this motor is easy since it only requires connection of the main voltage of 3x400VAC through the M23 connectors. Control voltage for the encoder and microprocessor circuitry is 24VDC: In an emergency-stop situation, where an approved relay has cut-off the main power, encoder position and other values are maintained by this control voltage. In some applications, however, this is not needed and in those cases an optional internal 24VDC supply can be used, requiring only an AC main connection. Furthermore highly effective switching technology is used to ensure low heat generation resulting in appreciable energy savings.

Other Advantages

One of the big advantages of using the integrated MAC motors is that you don’t need to install a separate servo driver or controller in a control cabinet. This gives you many subsequent advantages: Space savings in your control cabinet, saving of expensive motor and encoder cables, saving time (and money) for cabling, noise is minimized due to internal cabling and also installation errors between driver and motor are eliminated. In addition, service is much easier, since the motor and controller can be replaced as a single integrated unit. Hence downtime is minimized and production is maximized.

Motion Control Application – Implantable medication delivery systems: Where every microliter counts!

November 16th, 2020

Editor-Publisher

Motion Control – Application

Implantable medication delivery systems can have a decisive influence on the quality of life of the patients. In many cases, such delivery systems are vital for the survival of the patients – the systems have to be absolutely reliable. maxon motor manufactures high-precision micro drives for medication delivery systems.

Fall River, MA — Motion Control Components Application – Patients that suffer from chronic pain, metabolic disorders, diseases of the central nervous system and tumor diseases require accurately dosed medication. Here implantable medication delivery systems are used. Through the localized medication delivery, the dosage can be reduced to the required minimum. These infusion systems thus improve the quality of life of the patients. For many patients, it is only the medication delivery system that allows them to have a life outside of the clinic. Repetitive invasive, painful operations can be avoided. The risk of medication dependency and undesired side effects are reduced to a minimum. All these factors can contribute to the disease no longer being the central focus of the patient’s life.

For example, an active implant is implanted in the lower abdomen directly underneath the skin, where it delivers the medication dosage, programmed by the physician, to the body at the defined times of the day. The implantable unit has a wireless data interface to a patient interface by which the dosage can be adapted at any time. At regular intervals, the internal medication reservoir can be refilled by a specialist. The life span of the active implants measures many years and is limited only by the life of the battery. The core of the active implant is a piston pump manufactured by maxon medical, which specializes in medical technology and is a division of the maxon motor Group. However, the micro drives for implantable medication delivery systems are not comparable with customary maxon motors. In a customary motor, rotary motion is generated and yields torque and speed of rotation.

The reciprocating piston pump generates a linear movement that results in liquid pumping. The individual parts of the pump have very narrow tolerances and allow the pump volume to be adjusted with a precision of less a microliter per piston stroke.

As active implants are in direct contact with human tissue, biocompatible materials are an absolute requirement. Therefore, in most cases, titanium is used for the implants. Machining of titanium, especially safe and reliable laser welding, requires a very high level of expertise. Special testing and quality methods, such as inspecting the penetration depth, microhardness and density of the weld seams, are established procedures at maxon medical. The customer requirements on the product are thus fulfilled and the reliability and constant quality of the manufacturing processes are guaranteed. The entire assembly of the implantable micro drive takes place under cleanroom conditions.

maxon medical – Specialist for medical drive solutions and active implants

maxon medical specializes in the manufacturing of medical drive solutions for active implants. The division received ISO 13485 certification in December 2008. The quality management system and the project organization ensure safe, reliable and standard-compliant products and provide the customer with a sound basis for statutory approval of the final products.

Professional project organization and a proven risk management system allow efficient implementation of customer projects. Strict maintenance of statutory requirements has top priority in the implementation of medical technology projects with risk class IIb + III. Production processes, production systems and testing systems always fall under GMP (Good Manufacturing Practice, Commission Directive 2003/94/EC), regardless of the classification of the product.

maxon medical meets highest customer requirements – from selection of suitable suppliers to multi-tier quality control, from the individual parts to the final product. Manufacturing processes in the field of medical technology have very high documentation requirements during the entire value-added chain. All the way from the project idea to series production. In the end, a comprehensive and detailed documentation of all processes is required, including verification of process capability and traceability right back to the individual parts. This process control, matured to the last detail, characterizes maxon medical. It is an important and indispensable component of the entire production process and guarantees the high quality of the micro drives used for active implants of maxon medical.

Industrial Safety – Get a Free Gotcha Stick!

Industrial Safety — Omron introduces the safety Gotcha Stick Safe Distance Scale. This safe distance stick accurately tests the allowable barrier opening size based on the distance from the point of operation. It features English measurements on one side, and Metric measurements on the other.

Although not officially adopted by OSHA, the safety “Gotcha Stick” is based on data from “A Review of Machine-Guarding Recommendations,” by Donald R. Vaillancourt and Stover H. Snook of the Liberty Mutual Research Center for Health & Safety. This data redefines the dimensions of the human arm for the purposes of machine guarding. The resulting new stick has been modified to include openings of less than 1/4 inch over the first 1/2 inch distance.

Guarding machinery by means of hard (fixed) barriers is one of the main ways of protecting personnel from point-of-operation hazards. The safety “Gotcha Stick” is the easiest means of verifying that openings in hard guarding will not allow the point-of-operation to be accessed by the operator.

Omron’s safety products are used to protect workers around machinery, automated equipment and industrial robots. Their products serve a wide variety of applications and markets, including semiconductor, automotive, electronics manufacturing, packaging and consumer markets.

Linear Motion Application – How Do You Move Articles of Antiquity?

Very Carefully With A High Load Rail System from LM76!

Linear Motion - Moving Articles of Antiquity using LM76 Rail System

E. Longmeadow, MA – — The Boston Museum of Fine Arts (MFA) has to move articles of antiquity from one location to another. In this instance, they are moving a 5000 year old relief (hieroglyphics) weighing 8000 pounds to a new location in the Museum. Here is a frontal photo of the Relief from The Tomb of Senenuka.

Part of wall from tomb of Senenuka; nine stones fitting together and including two niches; lower left piece smooth limestone; upper far left preliminary black ink sketch; right of this sketch is a complete relief showing two seated figures; central piece has large scene of seated male on the left and other smaller male figure to the right; upper far right male figure relief outline; left of this again a scene of two seated figures at a table.

Senenuka Time of Khufu or Khafre (Maybe Dyn 5?) Overseer of the Pyramid-town of Khufu, Director of King’s wad-priests, Boundary official of a settlement, etc.

The MFA contracted CBI Consulting of Boston to design the frame and fixturing. Craig Barnes, an award winning architectural engineer called Mike Quinn of LM76 to review the linear motion application. Over the course of several weeks, LM76 and design partner Todd Kanipe designed a telescoping, high load roller/linear motion rail system that won approval. According to CBI’s Keith Bouchard, the linear rail system moves very smoothly and so far meets the expectations of this program.”

Linear Motion Application – According to MFA Antiquity Specialist Jean Louis Lachevere, “All of these moves present very real dangers to the artifact being transported. In this case, we have a 8000 pound relief which already has its problems due to age and the fact that it is limestone ( limestone is very vulnerable to the atmosphere ).” Seen from the front, the relief is straight. From the back, much of the top back is gone. Thus, the back of the relief has to be plastered so the back is flat. Pins are inserted to further reinforce the relief and then it is tipped on its back. It is then moved to its new atmospherically controlled display case. LM76’s design is used in the transfer from the dolly to the mounting rails and restraints in the display case. This 36” motion is fraught with things that can go wrong. One of the considerations is the possibility of an earthquake…any problem conceivable is taken into account.

Motion Control – Long Travel and High Torque Rotary Voice Coil Actuators from H2W Technologies!

October 15th, 2020

Editor-Publisher

Motion Control – High Torque Rotary Voice Coil Actuators

Santa Clarita, CA — Motion Control – H2W Technologies has developed several high torque rotary voice coil actuators, otherwise known as a limited angle torque motors or LATs. The model TWR-034-800-1RC was designed to allow for a relatively low moving mass and inertia, as well as a long rotary stroke of 34 degrees [0.59 radians] on a 11.4” [290 mm] arm, which equates to a travel of 6.75 inches [171.5 mm] which is long travel for this style of actuator, which typically restrained to an equivalent linear travel of 2 inches [50.8 mm]. This rotary voice coil actuator can generate a continuous torque of 1400 in-oz [9.8 N-m] and a peak torque of 4200 in-oz [29 N-m] at a duty cycle of 10% (i.e. 1 second on, and 9 seconds off) in each coil on a 11.4 inch [290 mm] rotation arm. The TWR-034-800-1RC has a total angular displacement of 34 degrees [0.59 radians] and a motor constant of 275 in-oz/sqrt(watt) [1.92 N-m/sqrt(watt)].

The Voice coil motor requires 1.7 amps of continuous current per coil and 5.1 amps of peak current per coil to generate the specified forces. The actuator fits in and envelope of 10.26 in [260.5 mm] x 3.01 in[76.4 mm] x 3.39 in [86 mm]. The moving coil design ensures a hysteresis free movement as the coil is wet wound and self-supported, and the non-commutated coil allows for ripple-free motion and no cogging. The voice coil actuator has been designed with mounting provisions in the magnet and coil assemblies. This allows for the integration of a bearing system to maintain the clearances between the coil and permanent magnetic field assemblies. The rotary voice coil actuator is ideal for applications requiring high torque and high- speed applications. Examples of such applications are driving a gimbal axis in scanning applications as well as providing stabilizing torques for image stabilization.

Motion Control – Miniature Linear Voice Coil Motor!

Van Nuys, CA — Motion Control Components – Moticont has added two miniature linear voice coil motors to its LVCM family of Linear Voice Coil Motors! Sharing the same physical dimensions, each is just 1.000 in. (25.4 mm) in diameter and the housings are 1.500 in. (38.1 mm) long. As every application is different Moticont offers two motor in the LVCM-025 Series of Voice Coil Motors. The LVCM-025-038-01 features a continuous force of 2.5 lbs (11.0 N) and a peak force of 7.8 lbs (34.7 N) and the LVCM-025-038-02 features a 1.000 in (25.4 mm) stroke, whereas, the LVCM-025-038-01 features a stroke of 0.37 in. (9.5 mm ) and the LVCM-025-038-02 features a continuous force of 16.4 oz (4.6 N) and a peak force of 51.9 oz (14.4 N).

Whether it is a longer stroke or a higher force that is required for an application, each of these highly efficient, clean, miniature brushless DC servo motors has high acceleration / deceleration, low inertia, and zero cogging, making them ideal for: Assembly, sorting, laser machining and drilling, haptic feed back, packaging, sampling, work holding and clamping, scanning, laser beam steering and filtering, wafer handling, and medical and pharmaceutical applications. Both the LVCM-025-038-01 and the LVCM-025-038-02 feature very high accuracy and repeatability when operated as a DC servo motor in a closed servo loop. Each linear motor also features a 10-32 UNC-2B threaded mounting hole in the housing and two 6-32 UNC-2B threaded mounting holes in the coil end on 0.50 in. (25.4 mm) centers for easy integration into new and existing applications. A complete plug-and-play system including an encoder and servo controller is also available.

If there a need for a still smaller or larger diameter motor, one with longer travel, or more force? There are 12 choices in this family of Moticont’s LVCM linear motors based on diameter of the motor, and over 50 models based on length of stroke and/or force to select from.
