Motion Control – Akribis Systems Voice Coil Motors & Voice Coil Position Actuators Available from Electromate!

Woodbridge, Ontario, Canada — Motion Control – A “voice coil” is a generalized term that refers to any galvanometer-like mechanism that uses a solenoid to move an object back-and-forth within a magnetic field.

Voice coil actuators, or non-commutated DC linear actuators, consist 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.

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

Electromate offers a full family of Voice Coil Motors & Voice Coil Modules from Akribis Systems. Features include:

• Direct drive, zero cogging, and zero backlash

Lead screw and high quality threaded nut for long service life

Medford, MA, Motion Control – Nanotec Electronic, U.S., Inc. has expanded the range of hybrid linear positioning drives by models in a NEMA 8 (20 mm flange size) and NEMA 14 (35 mm flange size). Linear positioning drives include a rotating screw mounted on the stepper motor. The linear movement is generated with the aid of an external nut. These motors are ideal for the design of compact linear axes as there is no need for the coupling and the bearing support point for the screw. The small linear positioning drives are used, for example, for scanning tasks in optical, mechanical or acoustic test equipment.

The hybrid linear positioning drives from Nanotec Electronic use special, maintenance-free thermo-plastic nuts. Despite its small size, the NEMA-8 model LS2018 delivers a force of 40 N and a step resolution of 0.005 mm. The NEMA-14 model LS3518 delivers a force of 140 N and a resolution of 0.01 mm. Standard screw lengths of 75 or 150 mm are available; customer-specific screw lengths can be optionally obtained. Both actuators can also be supplied with high-resolution (2000 incr./rev.) encoders.

Linear Motion Control Application – How Would You Position Components Of An Experimental Reactor Vessel Weighing 33 Tons?

Easy … Using Custom made LM76 Jet Rail Bearings and Shafting!

E. Longmeadow, MA –Linear Motion Control Application – When a privately funded research company was ready to move from their original Proof of Concept to a sustainable fusion reactor to produce clean sustainable energy, they realized that extremely heavy components would need to be assembled and disassembled and reassembled again for design modifications and maintenance. The completed assembly would be the length of two buses and easy alignment of the individual components would be critical.

The main reactor, the fusion containment chamber that is capable of containing a plasma medium of 10 to 15 million degrees is made of non-magnetic stainless steel as are many of the components. The Plasma Medium could be described as a football shaped blob about 1 meter in diameter by 2 meters long. The plasma medium is injected from each end of the reactor assembly by Plasma Guns.

See photo to right – On each end of the assembly is a Plasma Gun. The Plasma Guns as are all the floor lever components, are positioned using LM76 Jet Rail Bearings and shafting. The Jet Rail Bearings and Shafting can be seen near to bottom of the picture.

In addition to the reactor, high energy particle beam generators are positioned at angles to the fusion containment chamber. These particle bean generators form and suspend the plasma medium for an indefinite period of time in the center of the containment chamber. These generators have to be easily positioned – by hand – to accommodate adjustments and re-assembly.

See photo to the left – Neutral-Beam Injectors are positioned around the Reaction Chamber to position and shape the Plasma Medium. These are also moved into position on LM76 Jet Rail Bearings and Shafting.

In addition to supporting the weight of the components, the bearings selected to move these massive loads during the construction and testing of the fusion reactor would have to be non-magnetic. Working with engineers, LM76 developed a custom 3 inch Jet Rail Bearing designed to carry both the weight of the fusion reactor and the high energy particle generators. In addition LM76 supplied precision ground, 3 inch 303 stainless steel (non-magnetic) shafting.

The custom manufactured Jet Rail Roller Blocks and 303 stainless steel shafting simplified the assembly/disassembly of the fusion containment chamber and components while ensuring critical alignment throughout travel.

This breakthrough fusion reactor is still in the experimental stage. A commercially viable reactor would need to contain 100 million degrees. Why is the project so important? Because in addition to producing sustainable energy, its only by-product is, environmentally safe, “helium ash.”.

See photo below – The drawing below shows all the components in place. The assembly is 60 meters long and supported on LM76 jet Rail Bearings and Shafting.

E. Longmeadow, MA – -Linear Motion Application Story …

The Application –

Polishing Aluminum Truck Wheels is done with a polishing machine that has a 36″ vertical stroke indexer, having a 2500 pound load moving @ 4″ per second. The polishing media is like toothpaste with glass in it. It is extremely abrasive, and sticky/tacky.

The Problem –

The industrial buffing system is chewing-up linear ball bearings and spitting them out every 2 weeks! This is the situation one of customers found themselves in while for years accepting lost production and costly maintenance shutdowns. When LM76 got a call from a proactive new maintenance manager, we were eager to try a scraper seal design we had recently had success with on another application.

Originally, these systems came with protective bellows which helped keep polishing media from contaminating the 2″ linear ball bearing pillow blocks. According to our maintenance manager, once a bellow was damaged, it was removed and thrown away. Maintenance personnel so disliked having to take off and reinstall bellows that they mysteriously disappeared. Even with protective bellows, aluminum dust mixed with polishing media formed what one mechanic termed, “toothpaste with glass in it.”This abrasive “lapping compound”would stick to shafting, dry and semi-harden. As a bearing rolled along, polishing media would penetrate it’s seals “sliming” balls and clogging ball tracks. This would quickly lead to bearing failure and shaft brinneling (grooving). Needless to mention, routinely replacing linear ball bearings and more costly shafting was too much for the new maintenance manager who called LM76 for help.

The Solution –

For this application, we chose our Black Racer Ceramic Coated Linear Bearing. This bearing is extremely tough, is of one piece construction (no mechanical components, no catastrophic failure mode or shaft grooving) and has the longest life test we know of on record. Like linear ball bearings, Black Racer requires lubrication.

John Tarbell (President of LM76), specified a zero clearance beryllium copper scraper seal. Beryllium copper is exceptionally ridgid, extremely hard and wear resistant. The Beryllium copper would trap lubricant and distribute it as a fine, uniform film on the shaft. This film reduces friction, disperses heat and wets shafting. The wetted shaft surface forms a barrier between media and steel – keeping polishing media from cleating into disparities on the shaft (remaining peaks and valleys). Tarbel, said, “A Zamboni doesn’t lay down an inch of ice, it fills in the skate marks.” When the scraper travels on the shaft, it easily lifts the media and moves it along to the end of the stroke. Unlike linear ball bearings, Black Racer has no balls so some residual “slime” is easily accommodated. (Seen below, the beryllium scraper seal is captured between the bearing counter-bored face and the machined steel end cap.) Admittedly, a heavy interference fit dramatically raised system friction but was mitigated because the system is hydraulically driven – driving force is not an issue.

Staying within the form factor of the original OEM design–standard roundway pillow block and shafting–we chose our direct drop-in 2″ closed pillow block and Black Racer Ceramic Coated bearing coupled with our 2″, Class L Rc60 Case Hardened Shafting. Tarbell then designed a steel end cap retainer ring that pinned the beryllium scraper seal against the bearing face.

Note: The bearing leading and trailing faces have machined counter-bores to locate and capture the back of the scraper seal. To keep the retainer ring secured to the pillow block, set screws were positioned on both sides and driven into a slot machined into the OD surface.

Motion Control- Maxon motor launches the MAXPOS 50/5. This compact EtherCAT Slave unveils unprecedented possibilities as far as precision, dynamics, and synchronization are concerned. It also ensures reliability and durability even under harsh conditions. More than 20 years of experience in motion control have been incorporated into this latest technology in positioning controller.

Fall River, MA — Motion Control Controller – By their design, the ironless maxon DC brushed motors and brushless (maxon EC) motors are ideal for applications demanding high dynamics and longevity. Typical areas are robotics and applications in the medical industry or in specialized machine manufacturing. In the past when particularly high requirements were called for, the controller used or its limited integration capabilities to the master occasionally imposed limitations due to its inability to keep pace with the high dynamics of the motors. With the new MAXPOS 50/5 motion controller, these core motor properties can now be ideally utilized. Thanks to the latest FPGA (Field Programmable Gate Array) technology, highest control cycle rates can be achieved with minimally short cycle times at the same time. For trajectory planning, sophisticated motion control tasks with a current controller clock speed of 100 kHz and an effective communication cycle time of 100 μs can be achieved with a suitable EtherCAT master. Distributed Clocks Support as well as the endorsement of CoE (CAN Application Layer over EtherCAT) with «Cyclic Synchronous Modes» perfectly suit these purposes. As an alternative, profile-based operating modes for position and velocity are also available. In addition, the outstanding processing power provides field-oriented sinus commutation of brushless motors (maxon EC) up to a speed of 200,000 rpm.

Full connectivity

A multitude of feedback possibilities permit the use of a wide range of permanent magnet-activated DC motors with encoder and brushless motors (maxon EC) with digital Hall sensors and encoders up to 250 Watts. The wide supply voltage range from 10 to 50 VDC and the output power capability of 5 A continuous and 15 A peak current opens a broad application field. Two different encoders can be used simultaneously allowing for dual loop control of the master to compensate for mechanical backlash and elasticity of the drive system. This is ideal for applications with high demand on precision. The spectrum ranges from digital incremental encoders to analog sinus-cosinus incremental encoders up to absolute encoders with SSI, EnDat2.2, or BiSS-C interface. Of course, also galvanically isolated I/Os are on board to enable integration of diverse peripheral components, such as limit or reference switches.

All-around protection and easy operation

The MAXPOS 50/5 positioning controller also comes with extensive protective circuitry against overcurrent, excess temperature, undervoltage and overvoltage, voltage transients, short-circuits in the motor cable as well as loss of feedback signal. Motor and load can be optimally protected with adjustable current limiting.

The newly designed operating concept for the graphical user interface «MAXPOS Studio» together with well-established tools, such as Startup Wizard or automated Regulation Tuning ensures easy and intuitive commissioning. Additional aids include the Diagnostic Wizard for troubleshooting or a freely-configurable data recorder to plot various process data. Plus, to assist the customer in attaining the ideal matched drive system in the shortest possible time, a comprehensive document is provided. The entire configuration can be carried out via USB or Ethernet.
