Abstract

A fan and dust board device of an electric motor comprises a machine body and a main shaft, wherein, the machine body is internally provided with a stator and a rotor which is fixed on the main shaft; the main shaft is also provided with a collecting ring, a dust board is installed on the main shaft between the rotor and the collecting ring, and a fan is installed on the main shaft where the dust board is close to one side of the collecting ring. The invention has the beneficial effect that compared with an electric motor which does not have fan and dust board structure, the service life and the running reliability of an electric motor are greatly improved. The surface temperature of the collecting ring is lowered, the rigidity is enhanced, the service time of the collecting ring and an electric brush can be prolonged, the maintaining cost and the running cost are reduced, and convenience is brought to the users, thus saving social resource.

Description

technical field [0001] The invention relates to a motor, in particular to a fan and a dust baffle device on a winding rotor three-phase asynchronous motor in the field of hoisting and metallurgy. Background technique [0002] At present, the motors that are widely used in the lifting and metallurgical industry include: three-phase asynchronous motors with wound rotors for lifting and metallurgy, three-phase asynchronous motors for lifting and metallurgy, three-phase asynchronous motors with conical rotor braking for electric hoists, and three-phase asynchronous motors for lifting and metallurgy. Reuse basic series such as multi-speed three-phase asynchronous motors, rolling mill auxiliary drive DC motors, hoisting and metallurgical DC motors, and derivative series based on the above. AC motors are simple in structure, low in cost, and easy to use and maintain. They are the most widely used in crane electric drive devices, accounting for more than 90% of the total number of m...
