Compact electric rotary actuator

H2W Technologies Limited Angle Torque Motors are ideal for compact, limited angular excursion (<180º), rotary, closed loop servo applications. Unlike conventional rotary brush and brushless motors, the torquers are wound in such a way that no commutation is required for motion to occur. The result is a much simpler and more reliable system.

A DC linear servo amplifier is required to provide power to the torquer.

The torquers are typically supplied unhoused without bearings or a shaft, but can be supplied housed if required.

Coupling the torquer to your bearing system and a rotary encoder or other feedback device yields a system that is capable of intricate angular position, velocity, and acceleration control.

Low moving inertia of the rotor assembly allows for high angular acceleration of the payload.

The small length to diameter ratio allows the torquers to fit in spaces where conventional rotary brush and brushless DC motors will not.

It should be noted that, angular excursions of greater than 180º (up to 360º) can be achieved by modifying the winding of the stator assembly. In this case the coil assembly will have 4 leads and it will have to be commutated.

Advantages:

- No Torque Ripple
- High Angular Acceleration
- No Commutation
- Brushless
- Low Profile
