Applied Motion’s powerful stepper drive costs the same as a competitors drive without a built-in power supply!

Servo2Go-Logo

Greenville, DE –— The Motion Control STAC5 microstepping drive provides up to 5 amps per phase from a high bus voltage with sophisticated current control, delivering high torque over a board range of speeds. An advanced anti-resonance algorithm with electronic damping allows for maximum torque utilization and fast settling times.

The STAC5 microstepping drive is available in 120VAC and 220VAC versions, both housed in a compact package.

Applied Motion’s powerful stepper drive costs the same as a competitors drive without a built-in power supply, and features……

  • High performance
  • Built-in power supply & regeneration clamp
  • 120 and 220 VAC models
  • Accepts pulse & direction, streaming commands, stored programming
  • 10/100 MBit Ethernet & EtherNet/IP

Motion Control Tutorial – What is a Voice Coil Actuator?

Motion Control Tutorial – Understanding the Basics of a Voice Coil Actuator

 

Motion Control Tutorial – 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 – Steinmeyer Tutorial – Ball Screws – Maximum Load!

Motion Control Components - Steinmeyer Cooled Ball Screws

 

Steinmeyer Logo

 

 

 

 

 

 

Tutorial presented by Steinmeyer – Their Ball Screws are specially manufactured for dynamic performance

BURLINGTON, MA –Motion Control Tutorial – Ball Screws – Maximum Load

There are five ways a ball screw may fail due to overload:

  • Excessive dynamic loading, which means the screw makes too many revolutions under a certain load resulting in material fatigue. This can be avoided by selecting a ball screw with sufficient dynamic load capacity (or by reducing the number of revolutions and/or reducing the load). This is the subject of the load capacity discussion.
  • Exceeding the static load capacity, which causes instant and permanent damage to the ball screw due to brinelling of balls and races, and prevents any further normal operation of the ball screw. Static load capacities are listed as technical data.
  • Buckling of the shaft under compressive load. Buckling load value depends on bearing method and free length of the loaded ball screw shaft.
  • Failure of the nut body or of the bolts that connect it to the slide. This may happen even before the static capacity is reached. Safe loads are discussed on the following pages.
  • Radial loads. It means the load capacities given in this catalogue apply only to pure axial loading. As there are always tolerances in the alignment of bearings and linear guideways, there may be a small amount of radial force, which should be minimized. Under normal conditions, a radial load less than 5% of the minimum axial load will not cause any problems. When considering a ball screw for use under radial load, please consult Steinmeyer engineers.

BUCKLING

There are several analytical ways to demonstrate safety from buckling. In machine design, the most frequently used is a simple calculation using formulas based on Euler equations.

Other, more accurate methods include non-linear FEM analysis and more involved mathematics. These methods are normally used in aerospace applications, where excess safety margins are not possible due to weight limitations. Please contact us if you require such an analysis.

Please CLICK HERE for a simple form of buckling analysis. Buckling

FRACTURE LOAD

Some ball screws cannot be loaded all the way to their static capacity. Screws with high dynamic load capacity (which might be selected to obtain a long enough service life at a much lighter load) will necessarily have a high static capacity. But the term “static capacity” is misleading, since the ball screw may actually fail due to fracture of the nut flange, nut body, or connecting bolts before reaching this load!

Please CLICK HERE for the maximum safe loads. Fracture Load

TECHNICAL TIP

A reasonable load for a ballscrew, which may be sustained for significant travel, is about 10% of its dynamic capacity.

A mean load of 10% of its dynamic capacity results in a theoretical life of 1 billion revolutions, which is the upper limit of the range where the life equation is valid. Mean loads of a reasonably sized ball screw will therefore be somewhat higher than this, but normally not exceed 20% of its dynamic capacity.

For short peak loads, the loading may be higher, but normally the loading of a ball nut with 2-point contact should not exceed 2.8 times the preload. And preload is around 5% – 10% of dynamic capacity.

As a rule of thumb, this all means the load range for a ball screw, to be used in a machine tool application, is really about 10% to 30% of its dynamic capacity. However Steinmeyer ball screws are used in many applications as force actuators where the loading is up to 100% of dynamic capacity but with low speed and acceleration. For example, they may be used to power injection molding machines, where high forces occur at reduced speed. Please consult our engineers for details.

Is Your Work Place Safe? Find out with the safety Gotcha Stick!

 

STI — Omron introduces the safety Gotcha Stick Safe Distance Scale. This three-segment 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.

With headquarters in the heart of Silicon Valley, STI was founded nearly 30 years ago and employs more than 350 people. STI has been selected twice by Forbes and three times by Business Week as one of the “world’s best small companies.” STI’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.

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.

Motion Control – The Engineering Edge – One Piece FDA Linear Bearings and ETX Scrapers!

Motion Control - Engineering Edge -FDA Bearings/Scrapers

 

Motion Control – The Engineering Edge – Our latest linear bearing innovation is our FDL-ETX one piece bearing. ETX (FDA) Scraper Seals are machined into our Fluidline Linear Bearing. Our customer, a manufacturer of packaging machinery for the pharmaceutical industry, required FDA and washdown compliance. Further, they could not allow debris to include between the bearing and the shaft. They had been offered a number of catalog options that were close but no cigar! After reviewing the application, we approached them with this truly innovation option and it was well received and specified. At LM76 we distill down to the “right” design – we don’t saddle you with a catalog option.
