Torque Motors

VRAD Products can Function as Torque Motors

ScannerMAX VRAD actuators may perform well in the role of a limited-angle torque motor. Torque motors, (sometimes called torquer motors, or simply torquers) are a special class of motor, that are designed to operate within systems where the torque motor’s rotor is not allowed to rotate continuously, or perhaps at all. A wikipedia article providing more information on torque motors can be found online, by Clicking Here.

A few example applications for torque motors include: Force-feedback actuators, spring-loaded valve actuators, or tape/web tensioning arms on winding machines.

The VRAD Advantage Explained

VRAD stands for “versatile rotary actuator device”, and our VRAD rotary actuators all utilize a revolutionary new design, that features a unique magnetic spring return, very wide-angle capability, and a linear angle vs. current profile. The high coil resistance allows for low power consumption, and access to two individual drive coils allow flexible single-supply unidirectional, or bidirectional operation as well as dual-supply operation. Front and rear shaft allow multiple points of attachment, or for the use of an encoder or position for closed-loop operation.

The key innovation contained within our VRAD rotary actuators, is our patented stator design, that uses a series of asymmetrical, interleaved laminations that are inexpensive to make, easy to assemble, and which fit together in a way that prevents the introduction of air gaps to the motors magnetic field. By re-thinking the stator design, we’ve developed a more versatile, compact, and durable rotary actuator, that we are able to manufacture at a much lower cost when compared to other competing products.

The standard VRAD includes a magnetic spring return which, for small angle applications, would be virtually unnoticeable. For larger angle applications, we can tailor the spring return nearly to zero, so that the rotor will rotate freely over a peak-to-peak angle of 90° or more.
