Moving Magnet Non-Comm DC Voice Coil Linear Actuator, NCM03-20-005-3R
In certain uses of voice coil actuators there is a desire to manufacture them with increased radial clearance, while this lowers the overall efficiency, this allows for the motor to travel through an arc, and thus in some rotary applications the use of a voice coil actuator with an increased radial clearance, like this model (NCM03-20-005-3R), would be desirable.

Moving magnet actuators come standard with a linear bearing system. If you would like to see these actuators without a built-in bearing system please look at our moving coil models. Or if you would like to see how we have integrated our moving magnet voice coils into closed loop positioning stages please look at our voice coil positioning stages.

To determine your motion profile needs, use our linear motion calculator.
