Modular device used for circulation and storage of rotor assemblies of electric machine

Abstract

The invention discloses a modular device used for circulation and storage of rotor assemblies of an electric machine. The modular device comprises a plurality of supporting stand columns and a plurality of rotor assembly circulation tools, each rotor assembly circulation tool is provided with a circulation bottom plate and a plurality of rotor assembly chambers, each rotor assembly chamber is of ahollow columnar structure with an opening in one end, each rotor assembly chambers is arranged on the lower portion of each circulation bottom plates in an extending mode, each opening portion of each rotor assembly chamber is arranged on the upper surface of each circulation bottom plate, and each rotor assembly chamber is used for circulation and storage of the rotor assemblies. According to the modular device used for circulation and storage of the rotor assemblies of the electric machine, the percent of pass of finished and semi-finished rotor assemblies in circulation and storage is effectively ensured, the risk of electric machine operation is reduced, the production efficiency of the electric machine is improved, the production cost of the electric machine is reduced, the stabilityand consistency of the electric machine are improved, the service life of the electric machine in batches is prolonged, and the quality of the electric machine in batches is improved.

Description

technical field

[0001] The invention relates to a modular device, in particular to a modular device for turnover and storage of a rotor assembly of an electric motor. Background technique

[0002] After the motor is energized, the winding of the rotor assembly cuts the rotating magnetic field of the stator to generate induced electromotive force and current, forming an electromagnetic torque and commutating through the commutator to make the motor rotate. The current flows through the commutator of the rotor assembly through the graphite brush and through the commutator of the rotor assembly. Due to the high-speed friction between the silver-copper alloy sheet of the commutator and the graphite brush during the operation of the motor, the graphite brush wears out during the high-speed friction, and the life of the motor ends when the graphite brush of the motor is worn out. In order to effectively reduce the wear of graphite brushes, it is necessary to carry out precision tu...
