Abstract

The invention relates to the technical field of stepping motors, and concretely relates to an alternating current stepping motor. The motor comprises a shell, a front end cover, a rear end cover, heat dissipation holes, a stator, a coil, a rotor, a crankshaft, a bearing, a step groove, a lubricating mechanism and a fan, the front end cover and the rear end cover are movably installed at the front end and the rear end of the shell respectively, and the heat dissipation holes are formed in the surfaces of the front end cover and the rear end cover. The stator is fixedly installed at the inner edge of the shell, the coil is movably installed in the stator, the rotor is movably installed at the inner center of the shell, the stator does not make contact with the rotor, and the bearings are movably installed at the front end and the rear end of the outer surface of the crankshaft and fixedly connected with the front end cover and the rear end cover. According to the alternating current stepping motor, airflow generated when the motor works and dissipates heat can be used as power to smear lubricating oil on the stator in the motor, so that the purpose of rust prevention is achieved, meanwhile, the lubricating oil is not prone to dripping in the smearing process, the risk of coil short circuit is reduced, and the service life of the motor is guaranteed.

Description

technical field [0001] The invention relates to the technical field of stepping motors, in particular to an AC stepping motor. Background technique [0002] A stepper motor is a motor that converts electrical pulse signals into corresponding angular displacement or linear displacement. When working in an environment with high air humidity, the inside of the stepper motor is easily damp and rusted. When the stator is rusted, the rust will It hinders the rotation of the rotor, thus affecting the normal operation of the motor. [0003] Existing patent (notification number: CN211481051U) a rust-proof hybrid stepping motor, including a base, the top of the base is welded with a mounting frame, the top of the mounting frame is welded with a metal motor casing, and the metal motor casing A motor cover is mounted on a bolt at one end, a motor shaft is installed on one end of the metal motor case, and a sealed bearing is installed on the bolt between the metal motor case and the mot...
