Properties:

A motor whose rotating member is limited in travel to less than one mechanical revolution or travel at a speed much lower than a conventional motor. It is designed to convert an electrical energy input into a fast-responding mechanical motion output in the form of a constant torque. It does not include gear box(es) or gear train(s), commutators, brushes, or slip rings. The output torque may be exerted through a rotational travel movement or while operating in a continuously stalled or intermittently stalled condition. Excludes electromagnetic actuator; motor, control; and solenoid, electrical.
