An AC gear motor is a type of electric motor that converts AC power into mechanical power with the help of gears. An AC gear motor consists of an AC induction motor and a gearbox. The AC induction motor is a motor that uses electromagnetic induction to create a rotating magnetic field that drives the rotor. The gearbox is a device that uses gears to reduce the speed and increase the torque of the rotor. An AC gear motor has advantages over DC gear motors, such as higher efficiency, lower maintenance and better performance at high speeds. An AC gear motor is often used in applications that require constant speed and AC power supply.
