Abstract

The invention relates to a manufacturing and processing technology for a cast-aluminum rotor of a three-phase asynchronous motor, a manufacturing and processing device for the cast-aluminum rotor of the three-phase asynchronous motor is used, the manufacturing and processing device for the cast-aluminum rotor of the three-phase asynchronous motor comprises a bottom plate, supporting mechanisms and polishing mechanisms; the bottom plate has a circular disc structure; supporting mechanisms are symmetrically installed on the upper end face of the bottom plate, and the polishing mechanisms are installed on the supporting mechanisms. Problems that an existing cast-aluminum rotor machining device cannot stably lock and fix a cast-aluminum rotor, so that the cast-aluminum rotor is prone to shaking when end teeth are polished, and the polishing precision and the smoothness of the surface of the polished cast-aluminum rotor are affected are solved. And the problems that an existing cast-aluminum rotor machining device cannot conduct reciprocating polishing on end teeth at the two ends of the cast-aluminum rotor formed through pouring at the same time, the polishing efficiency is low, and time is wasted can be solved.

Description

technical field

[0001] The invention relates to the technical field of three-phase asynchronous motors, and specifically proposes a manufacturing process for a cast aluminum rotor of a three-phase asynchronous motor. Background technique

[0002] Three-phase asynchronous motor (Triple-phase asynchronous motor) is a kind of induction motor. It is a type of motor powered by simultaneous access to 380V three-phase AC current (phase difference 120 degrees). Since the rotor and stator of the three-phase asynchronous motor rotate The magnetic field rotates in the same direction and at different speeds, and there is a slip, so it is called a three-phase asynchronous motor. The rotor speed of the three-phase asynchronous motor is lower than that of the rotating magnetic field. The relative motion between the rotor winding and the magnetic field generates electromotive force and current, and interacts with the magnetic field to generate electromagnetic torque to realize energy conver...
