Vaughan, Ontario, Canada — Motion Control Components — The EDD-3701x EtherCAT slave drive joins Galil’s EtherCAT Family. This family has grown to include two EtherCAT masters and an I/O slave with both digital and analog I/O points. The EDD-3701x is a motor amplifier that operates in an EtherCAT distributed system where there are up to 32 slave drives and one master. It has a daisy chain topology using standard CAT5 Ethernet cables. The EDD-3701x can interface with Galil masters (DMC-500×0 and DMC-52xx0) for sophisticated applications or with TwinCAT® for very simple applications.

The EDD-3701x series has the ability to control brushed, brushless, steppers, and microstepping motors (See Table 1 for more details). Unlike the competition, the EDD-3701x can both control a motor and also has 8 digital inputs, 4 digital outputs, 2 analog inputs, and 2 analog outputs. All I/O information from these drives are accessible by the EtherCAT master. This capability can eliminate the need for separate EtherCAT I/O devices. The configuration of the EDD-3701x is done using the Galil’s GDK software. Simply connect to a PC via EDD-3701x’s USB port, follow the GDK configuration tool process, and start moving motors. The EDD-3701x also comes with a setup guide to get the user from taking the EDD out of the box to moving motors in a manner of minutes

The EDD-3701x has a small form factor with just 3.9”x5.0”x1.5”. It can operate in either Cyclic Synchronous Position mode (CSP) or Cyclic Synchronous Torque mode (CST). It also accepts quadrature encoder feedback up to 15 MHz.

The Engineering Edge – Application – Trunnion Grinding Slide for Oil Field

 

We are shipping another slide today for the oil patch. When Weir Oil and Gas called with a slide application that required special engineering, LM76 was all ears – as it was right up our alley. This slide is a Trunnion Grinding Slide which has a 56HP motor running at 3500 RPM mounted to the Y Axis – with a 12″ grinding wheel attached. The X Axis (52″ Stroke) runs on 440C stainless linear ball bearings that have special beryllium copper scraper seal cartridges while the Y Axis (4″ Stroke) employs profile rail guides with double scraper seal kits. Our customer did not want protective bellows so we had to ensure grinding debris would not cause bearing or screw/nut failures. On both axis, we employed our proprietary “Polymatrix, Double Preloaded Nuts” as opposed to recirculating ball nuts. Why LM76? Good question…we were the only company that got back to them with a thoughtful solution.

Motion Control – Compact Linear Induction Motor Is Available from H2W Technologies!

H2W Logo

Santa Clarita, CA —– Motion Control – H2W engineers have developed a compact Linear Induction Motor (LMAA-04-01) that can generate 10.6 lbs [47 N] at a 15% duty cycle. Operating at 208 VAC 3-phase 60 Hz, the synchronous velocity of this LIM is 160 in/sec [4 m/s]. This LIM was designed for high speed operation; however, it can also be operated at stall (zero speed) to produce static thrust. This motor is encapsulated using high temperature 350°F [176°] potting compound which protects the components and seals it from moisture.

A non-contacting, high speed, linear motor measuring just 8.7 in. [223 mm] long x 3.0 in. [75 mm] wide x 1.7 in. [43 mm] high this LIM operates on the same principal as a rotary, squirrel cage, induction motor. They are typically used in applications that do not require positioning.

The 3-phase coil assembly can be directly connected to the AC line for single speed applications or to an adjustable frequency drive for variable speed control of the motor. The motors are reversible and can also be dynamically braked.

The laminated coil assembly is used in conjunction with a customer supplied aluminum and steel reaction plate to produce a force. A customer supplied bearing system is required to maintain the .125 in. [3.0 mm] air gap between the coil assembly and the reaction plate. The length of the reaction plate is typically equal to the coil assembly length plus the stroke.

Advantages:

  • Only 2 Parts
  • Wide Speed Range
  • No Maintenance
  • Non-contact
  • Ease of Control and Installation

Typical LIM Applications:

  • Conveying Systems
  • Baggage Handling
  • Personal Rapid Transport Systems
  • Theme Park Rides
  • Active linear braking systems

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 Application – Intelligent robot systems are increasingly being used in disaster control, rescue missions and salvage operations!

After the severe earthquake in Japan and the subsequent nuclear disaster in Fukushima, Quince managed to reach the upper floors of the ruins of the power plant. There it measured the radioactivity levels and sent HD images to the world outside.

Wherever it is too dangerous for humans. Robots that can look for survivors after an explosion, an earthquake or other natural disasters, providing humans with a view of inaccessible areas. Powerful EC motors from maxon motor give the Japanese rescue robot “Quince” its drive.motion control application robot Quince

 

Maxon Logo

Fall River, MA — Motion Control Components Application – Robots that are used in disaster areas have to have a very high level of adaptability. They have to be fairly small, not too heavy and maneuverable enough to get through cracks or narrow spaces to reach areas deep inside a building. Furthermore rough terrain should present no problem. These rescue robots enter and explore buildings to determine if there are gases, radiation or other life-threatening hazards, before human rescue teams can search the area. Quince has proven that it fulfills all these demands. After the severe earthquake in Japan and the subsequent nuclear disaster in Fukushima, Quince managed to reach the upper floors of the ruins of the power plant in June 2011. There it measured the radioactivity levels and sent HD images to the world outside (To see video – CLICK HERE). The robot was able to supply valuable information from areas where no human can set foot.motion control robot goes down stairs

Quince weighs 27 kg and is equipped with four moving caterpillar drives (flippers). These flippers automatically adapt their angular position to the surface underneath – regardless of whether the robot is climbing steep stairs or crossing rough terrain. Correct ground contact is a very important prerequisite. This contact is accurately analyzed by measuring the power consumption of the flipper motors. Furthermore PSD (Position-Sensitive Device) sensors on the front and rear flippers measure the distance to the ground. In addition to a gripper arm (see fig. 2), two laser scanners can also be attached to the robot. These scanners are capable of accurately capturing the structure of the terrain.motion control robot navigates rough terrain

Additionally Quince is equipped with a “bird’s eye camera” and can travel quite fast, at 1.6 meters per second. The operator that controls the robot has to tell it which direction to take, but the robot itself determines the optimal flipper positions for crossing various surfaces, for example stairs. Newer Quince motors have additionally been equipped with a device for collecting radio-active dust or ultra-fine particles, as well as a 3D scanner. To ensure that no robot is lost, a connection to a wireless network is possible, which is the only way to navigate the robot if the connection cable breaks.

The rescue robot was developed by Eiji Koyanagi, Vice-Director of the Chiba Institute of Technology Future Robotics Technology Center (fuRO). Koyanagi started his career as a teacher – at the age of 51, he became a professor. This means that he has a completely different background than other researchers in the field of robotics. Quince has been specially designed for extreme conditions in environments where it would be too dangerous for humans. Therefore its main area of application is disaster areas. “When you develop a robot, you first have to consider the tasks that it will perform later. That is the biggest challenge,” explains Koyanagi. Hitherto eight Quince robots have been built. But before this could be done, all components had to be 100% functional. To this end, various trials were run in the large “Disaster City” training area in College Station, Texas. Quince was the only robot that successfully completed the entire obstacle course at the site as part of a RoboCup contest. In preparation for using the robot inside the Fukushima Daiichi nuclear power plant, several specific customizations were required. “The conditions in the nuclear reactor buildings are very tough. If we had attempted to send Quince in without modifications, it would probably have met its end,” says Koyanagi. Therefore the robot had to be able to survive a fall from approx. 2 m high unscathed, and had to be largely maintenance-free.

Powerful motors to beat every obstacle

Motion Control -Maxon Motors used in robot Quince

Where the motor selection was concerned, fuRO required absolutely reliable drives. The motors have to provide high power and high efficiency, yet be small and light. These requirements were precisely met by maxon motors, explains Koyanagi. Six powerful maxon motors drive the robot. The brushless EC-4pole 30 direct current motors each provide 200 W; two of these have been installed in the two main chains. The powerful 4-pole units give their all when Quince maneuvers its way across uneven terrain. Four additional motors (EC22) drive the moving chain drives (flippers). These can automatically adapt their angular position to the surface below. The 3D scanner unit of Quince is moved to the right position by an RE-max 24. Thanks to the special winding technology and the 4-pole magnets, the maxon EC-4pole drives are unbeatable when it comes to delivering the highest driving power per unit of volume and weight. The motors have no cogging torque, high efficiency, and excellent control dynamics. The metal housing additionally ensures good heat dissipation and mechanical stability. All motors of the chain drives have been combined with the GP32HP (High Power) planetary gearhead with MR encoder. This gearhead was customized by installing a large ball bearing and a reinforced motor shaft. With this power pack, Quince has no trouble managing almost any obstacle.

Motion Control – Linear – High Torque Rotary Voice Coil Actuators!

Linear Motion Control - H2W High Torque Voice Coil Actuators

 

Linear Motion Control - H2W Logo

Santa Clarita, CA —– Linear 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-015-346-2RC was designed to allow for a low moving mass (68 grams per coil) and inertia, as well as dual independent coils to allow for two independent motion profiles or couple the coils together to double the torque output. This rotary voice coil actuator can generate a continuous torque of 185 in-oz [1.29 N-m] and a peak torque of 555 in-oz [3.88 N-m] at a duty cycle of 10% (i.e. 1 second on, and 9 seconds off) in each coil on a 4 inch [102 mm] rotation arm. By coupling the coils together, the continuous torque doubles to 370 in-oz [2.58 N-m] with a peak torque of 1110 in-oz [7.75 N-m] at a 10% duty cycle.

The TWR-015-346-2RC has a total angular displacement of 15 degrees [0.26 radians] and a motor constant of 34.4 in-oz/sqrt(watt) [0.24 N-m/sqrt(watt)] per coil or when coupled together the motor constant is 48.5 in-oz/sqrt(watt) [0.34 N-m/sqrt(watt)]. The voice coil motor requires 1.33 amps of continuous current per coil and 4.0 amps of peak current per coil to generate the specified forces. The actuator fits in and envelope of 4.37 in [111.1 mm] x 2.99 in [75.9 mm] x 1.64 in [41.5 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. More examples of H2W’s Rotary Voice Coils are available on our website: https://www.h2wtech.com/category/rotary-voicecoil-actuators

Technology

Simply stated, a current carrying conductor placed in a magnetic field will have a force (or torque) exerted upon it. This force is proportional to the direction and magnitude of the current and the flux density field. Since the permanent magnet flux density field is fixed, the direction of the rotation depends on the polarity of input current and the amount of torque that is produced is directly proportional to the magnitude of the input current.

Rotor: The rotor is made up of a single coil of bondable copper magnet wire. The coil is wound and preformed into the desired shape. It is held together with the bonding agents in the wire. It can be encapsulated with aluminum or plastic brackets in order to provide a means for mounting the rotor to the bearing system and payload. The maximum angular excursion is less than 90º.

Stator: The stationary stator assembly consists of multipole permanent magnets that are bonded to steel plates. The 2 opposing steel plates are spaced apart to provide a gap using end plates. The coil rotor assembly moves angularly within this gap. There is no magnetic attractive force between the stator and the rotor.

The TWR Series Torquers are available in 2 configurations.

The low profile (Type L) configuration has a smaller overall height which allows it to fit in a more compact space, but has less angular rotation for a given stator arc segment.

The second configuration (Type S) has a larger overall height but has typically twice the angular rotation per given stator arc segment when compared to the Type L torquer.
