Limited Angle Torque Motor, TMR-150-23-010-2
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.

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