Description

Technical Field

[0001] The utility model relates to the technical field of synchronous motors, in particular to a storage rack for producing permanent magnet synchronous motors. Background Art

[0002] The synchronous motor, like the induction motor, is a commonly used AC motor. The synchronous motor is the heart of the power system. It is a component that integrates rotation and stillness, electromagnetic changes and mechanical movement to realize the conversion of electrical energy and mechanical energy. Its dynamic performance is very complex, and its dynamic performance has a great influence on the dynamic performance of the entire power system. The characteristic is that during steady-state operation, there is an unchanging relationship between the rotor speed and the grid frequency n=ns=60f / p, where f is the grid frequency, p is the number of pole pairs of the motor, and ns is called the synchronous speed. If the frequency of the grid remains unchanged, the speed of the synchronous motor is always a constant in the steady state and has nothing to do with the size of the load. Synchronous motors are divided into synchronous generators and synchronous motors. The AC machines in modern power plants are mainly synchronous generators.

[0003] After retrieval, Chinese patent CN215514698U was found and disclosed a storage device for the production of motor accessories. A polished carbon brush enters through a feed port and is wiped by two wiping rollers to clean the carbon powder on the surface and drop it into a storage box for subsequent use. The scraper can clean the carbon powder on the surface of the wiping roller and make it fall into the storage chamber to extend the service life of the wiping roller. This patent realizes the storage of carbon powder, but does not perform storage work on motor accessories or components. During the production of synchronous motors, multiple motor accessories or components will be processed. In this way, the motor accessories or components need to be placed together for storage and storage, and the motor accessories or components need to be taken out before the next process. For this reason, a storage rack for the production of permanent magnet synchronous motors is proposed. Utility Model Content
