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.

Vaughan, Ontario, Canada — Motion Control Components — Tecnotion, long known as “The Linear Motor Company” entered the rotary torque motor market last year with a new design for torque motors. By new design, we mean the magnetic design is optimized for maximum flux density and copper fill to provide very high torque to volume ratios.

Manufactured in volume, these new Tecnotion Torque motors feature encapsulated windings and include two types of thermistors as standard features at very competitive pricing. Tecnotion offers motor sizes from 68mm to 160 mm diameters, to date, these motors pack serious power and will work with any servo drives in the market, or of your design.

Torque Motors from Tecnotion are extremely compact, provide an extremely stiff drive train, eliminate the need for time-consuming mounting procedures, are virtually maintenance free and can be integrated directly into the machine structure, while the spacious open inner diameter enables wire and cable feedthrough. To top things off the entire series comes with completely sealed stators and integrated temperature protection and measurement sensors.

With continuous torque ratings ranging from 0.27 Nm to 63.5 Nm and speed ranges from 190 rpm to 6918 rpm, these motors can play a pivotal role in increasing the availability and cost-effectiveness of many different applications in industries like:

  • Semiconductor
  • Printing
  • Robotics
  • Machine tooling
