Motion Control – Custom Linear Mechanisms

Custom Linear Mechanisms from Steinmeyer …

Welcome to Where Precision Is.  You Can Turn to Steinmeyer for Design and Assembly of Custom Linear Mechanisms for your Precision Positioning Systems
Modern mechatronic systems consist of numerous precision components that must be assembled in complex configurations. Here, every detail counts.Steinmeyer Mechatronik, a division of August Steinmeyer GmbH, offers design and assembly services for a variety of demanding applications.We have deep experience in medical devices, laboratory instrumentation, optical inspection & semiconductor positioning. Our engineers can implement your finished design or optimize your concept.

For Example …

Zoom Unit

Sliding axes for the adjustment of two optics

Two lenses must be positioned relative to each other and also positioned together. Since the unit is exposed to stray radiation from the exposure process, lubrication must withstand these conditions in the long term. The basic solution consists of two sliding axes on a common guide system. Two moving sliding carriages have three carriages each, which allows them to move partially within each other in order to bring the lenses together as closely as possible. The drives consist of smoothened ball screw drives driven by a direct current motor with a rotary encoder. The motor encoder assembly is designed to be interchangeable for easy maintenance.

Designed for extremely dry environments

By choosing a PFPE-based lubricant and a special surface coating, the requirements for clean room compatibility and UV resistance were met. All accuracy-relevant parameters are verified by a measuring station after installation. This measuring station is located in the clean room and records accuracy, repeat accuracy, straightness, evenness and current consumption. Additional tests are performed to ensure minimum clearance in the bearing and smooth running of the drive system.

Steinmeyer has decades of experience in precision assembly. All of our systems, whether single or multi-axis, are manufactured carefully. Our high standards, monitored continuously through vigorous quality systems, are evident in every assembly we produce. We pay attention to every detail.

Motion Control Tutorial – What is a Voice Coil Actuator?

Motion Control – Understanding the Basics of a Voice Coil Actuator

 

A voice coil actuator, also known as a non-commutated DC linear actuator, is a type of direct drive linear motor.  The name “voice coil” comes from one of its historically first applications: vibrating the paper cone of a loudspeaker.  They are currently used for a wide range of applications, including moving much larger masses.  It consists of a permanent magnetic field assembly (permanent magnets and ferrous steel) and a coil assembly.  The current flowing through the coil assembly interacts with the permanent magnetic field and generates a force vector perpendicular to the direction of the current.  The force vector can be reversed by changing the polarity of current flowing through the coil.

A non-commutated DC linear actuator, typically referred to as a voice coil, is capable of a displacement of up to 5 inches, whereas most actuators have displacements up to 2 inches.  Voice coils come in a range of sizes, from devices that generate a few ounces of force, to others that generate several hundred pounds of force.  In addition, voice coil actuators can move bi-directionally, have a constant force over the stroke, and can be used for either open loop applications or closed loop position or force applications.

A voice coil actuator generates a force based on an interaction of current carrying conductors in a permanent magnetic field.  The force generated by the voice coil is proportional to the cross product of the current flowing through the coil and the magnetic flux in the permanent magnetic field, as dictated by Lorentz’ force equation:

F = B x I

F= Force (lbs or N)
B = Flux density (Tesla)
I = Current (Amps)

The force generated is relatively constant throughout the stroke of the actuator, with minor decreases in force at the beginning and end of the stroke.

Either the coil assembly or permanent magnetic field assembly can be used as the moving member in a voice coil actuator.

Moving Coil

Voice coil actuators come in a variety of packages.  The standard type, which most people are familiar with are moving coil type actuators.  These typically involve a coil wound around a bobbin, which can be made from many non-magnetic materials, which moves in and out of a permanent magnetic field assembly consisting of a steel housing with a concentric permanent magnet assembly in the middle.  A typical example can be found below:

Moving Magnet

Another common type of actuator would be the moving magnet design, where the coil is fixed and magnet assembly moves.  This construction change would prevent moving leads during operation.  The package operates similarly, but instead of an exposed coil that moves in and out of the magnet assembly, the moving magnet style utilizes a permanent magnetic field assembly “piston” moving inside a cylindrical coil tube.  This style often comes with the permanent field assembly attached to a shaft, and end caps containing bearings so that this style is most commonly supplied with an integrated bearing system.  A typical example can be found below:

There are variations on both common designs of either actuator design that allow for unique geometry, and the integration of voice coil actuators into several applications.

A few examples of customizations available are:

  • Large radial clearances so that the voice coil can be used in limited rotation applications
  • Designs that intentionally operate the voice coil motor in an arc (commonly referred to as a rotary voice coil actuator)
  • Using low outgassing materials to enable use in vacuum environments
  • Integration of feedback devices for closed loop control

Voice coil actuators are typically used in focusing applications, oscillatory systems, mirror tilting, and miniature position control.

Advantages of Voice Coil Actuators

  • Simplicity of construction
  • Very low hysteresis
  • Small size
  • High accelerations
  • No cogging or commutation

Motion Control Application- Vacuum Compatible Maxon Motors for Extreme Conditions!

Maxon Motor spent several months working alongside Instrument Design Technology (IDT) to customize a small, brushless motor to perform in the extreme vacuum conditions of the synchrotron. This article highlights the challenges in the design.

Fall River, MA — Motion Control Components Application – The Diamond Light Source particle accelerator in Oxfordshire has been used for projects as diverse as analyzing the effects of strain on aircraft wings, studying the behavior of the HIV virus, and even reading ancient letters without opening them. The 45,000m2 synchrotron facility works by accelerating electrons to 3GeV, generating beams of synchrotron light, up to ten billion times brighter than the sun, in order to understand molecular structures. To prevent electrons being lost in collision with air molecules, the whole process is undertaken in a vacuum; around one billion times lower than atmospheric pressure. Clearly, creating scientific instrumentation for such conditions requires great specialist knowledge, and Widnes-based Instrument Design Technology (IDT) supplies the world’s leading synchrotron facilities.

Motion Control Application Maxon Motor for Synchrotron

Diamond specified that the Double Crystal Monochromator for its new X-Ray Spectroscopy Beamline B18 should drive the crucial Bragg rotational axis with a DC motor rather than the usual stepper motor. IDT managing director Paul Murray explains: “The goal was to achieve higher rotation speeds, with a lower motor temperature and smoother drivetrain than the stepper motor we had used previously. Stepper motors are inherently noisy, and often sources of vibration. Eliminating this issue would immediately improve results from the DCM – but the new motor would have to work flawlessly in a vacuum of 10-8 Torr.” To help solve the problem IDT enlisted the help of Paul Williams, senior sales engineer at maxon motor UK. With experienced engineers handling the project at every stage, and a long history of customizing high-performance motors for applications as demanding as space and surgical robotics, maxon’s teams in Britain and Switzerland were eager to rise to the challenge of creating a cutomized solution. Williams says: “Because the vacuum in the synchrotron must not be compromised, each individual aspect of the motor and its construction had to be analyzed for possible outgassing. The challenge for us was effectively to create a brushless motor with virtually no glues or plastics, an incredibly high temperature tolerance, and excellent performance.”

The starting point for the custom motor was maxon’s EC22 Heavy Duty Motor. Although originally developed for sub-sea oil applications, the 22mm brushless motor’s laser-welded stainless steel construction and broad temperature range already addressed many of the needs of high vacuum applications – and being a brushless DC motor meant it would immediately be more efficient, quiet and responsive than the previous stepper motor.

Maxon Motor for Application in Synchrotron

When customizing the EC22 HD for use in the synchrotron, maxon accounted for a number of factors. First among these was temperature management. Motors in a vacuum cannot dissipate heat through convection in the normal way, so can be prone to overheating. It is therefore important to choose a motor with high temperature tolerance, stay well within its rated performance in air, and, if possible, position other components in such a way as to spread heat by conduction. A high ratio gearbox was also vital. High vacuums of 10-7 Torr and greater can pull gaseous compounds from materials such as plastics and glues, compromising performance and contaminating the vacuum – a problem known as outgassing.

Each component in the motor was individually tested, and upgraded as necessary. For example, standard PVC cable coating was replaced with a more inert, Kapton version. It was therefore important that the EC22 HD was already substantially made from stainless steel, rather than plastics. Because of the potential for outgassing, the usual glues and epoxies could not be used, and the motor was put together using extensive micro laser welding. From its work with space and aerospace projects, maxon knew how standard, light greases used on motor bearings are affected in low pressure conditions. It was therefore important to specify an extremely inert lubricant which was also thick enough to avoid giving off vapor under high vacuum – and to account for the effect of this change on the motor’s operating characteristics and anticipated life cycle. To finally remove any remaining outgassing threat, motors for controlled vacuum conditions are baked at 120ºC for 24 hours. Already purpose-built for temperatures in excess of 200º C, the EC22 HD proved an ideal starting point.

The Double Crystal Monochromator, incorporating the special maxon DC motor, is now in active service in Diamond Light Source’s Beamline B18, playing its role in key experiments on a daily basis. As an example, a group of Italian scientists used Beamline B18 to study dust in snowflakes that fell some 800,000 years ago – about the time of the first hominid life on Earth. Ice cores drilled from the Antarctic are made up of layers of frozen snow, dating back hundreds of thousands of years… and minute dust particles trapped as the snow fell hold key information about the earth’s climate, atmosphere and volcanic activity at the time. Using X-Ray Absorption Spectroscopy, the scientists were able to study the mineral composition of the dust, determining its origin, and unlocking clues to the changes in global climate patterns over hundreds of millennia.
