Understanding AC Gear Motor Design

Sinotech    December 21, 2012

AC gear motors are electric motors that use an alternating current. They generally have two parts: the outside stationary stator and the inside rotor. Slip rings or a permanent magnet generate the magnetic field on the rotor. The stator has coils that receive an alternating current, which produces a magnetic field that rotates. An output shaft that’s attached the inside rotor of the AC gear motor acquires torque via the rotating field. The two most common types of AC gear motorsare synchronous and asynchronous motors. AC Synchronous Motors In synchronous motors, the rotation of the output shaft is synchronized with…
