Abstract

The invention belongs to the technical field of motors, and particularly relates to an alternating current (AC) stepping motor which comprises a motor body, a sound insulation box, a base, a vibrationreduction unit, a noise reduction unit and a holding unit. The periphery of the motor body is sleeved with a sound insulation box which is in a closed cylinder shape; the motor body is connected withthe sound insulation box in a sliding manner, the sound insulation box absorbs the transverse vibration of the motor, and the sound insulation box is used for reducing the noise transmission generated by the motor body during working; a base is arranged below the sound insulation box, a group of vibration reduction units are arranged between the base and the sound insulation box, and the vibration reduction units are used for reducing vibration of the motor body; a silencing unit is arranged in the middle of the base, and a retaining unit is arranged between the end surfaces on the two sidesof the motor body and the sound insulation box; and the motor body, the sound insulation box, the base, the vibration reduction unit, the noise reduction unit and the holding unit are mutually matched, so that the vibration of the motor body is reduced while the noise of the motor body during working can be reduced.

Description

Technical field [0001] The invention belongs to the technical field of motors, and specifically is an AC stepping motor. Background technique [0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses energized coils (that is, stator windings) to generate a rotating magnetic field and act on the rotor (such as a squirrel cage closed aluminum frame) to form a magneto-electric power rotating torque. Motors are divided into DC motors and AC motors according to different power sources. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (motor stator magnetic field speed and rotor rotation speed do not maintain synchronous speed). The motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic line of induction (magnetic field direction). ...
