Abstract

The invention relates to a bearingless permanent magnet sheet motor which is easy to overhaul. It includes a casing, the inner wall of the casing is provided with a connecting ring formed integrally with it, and the bottom of the connecting ring is provided with an inner casing connected to it by several screws and has an open bottom. , the inside of the inner shell is provided with the main body structure of the motor, and the top of the shell is provided with an end cover fixed on the shell by screws. Reinforcement ring, the side wall of the reinforcement ring is provided with a reinforcement bar fixed on the top of the end cover, the bottom of the end cover is located at its center and is fixed with a cushion plate, and the shell includes an upper shell and a lower shell; the present invention sets the shell and The inner shell and the outer shell are composed of an upper shell and a lower shell. The upper shell and the lower shell are connected by a lock, and the inner shell is connected with a connecting ring by a number of screws, which is convenient for disassembly and installation of the outer shell and the inner shell.

Description

technical field [0001] The invention relates to the technical field of permanent magnet flakes, in particular to a bearingless permanent magnet flake motor which is convenient for maintenance. Background technique [0002] As a new type of bearingless motor, the bearingless permanent magnet sheet motor combines the advantages of both the bearingless motor and the permanent magnet synchronous motor. While realizing mechanical zero contact, it also has the advantages of simple structure, easy control, high speed and high precision. Etc. Bearingless permanent magnet sheet motors can be used in centrifuges and centrifugal pump systems in a non-contact, pollution-free, and completely sealed working environment to meet various extreme work requirements. Therefore, they are widely used in precision instrument manufacturing, flywheel energy storage, and biomedicine. In fields such as life sciences and life sciences, bearingless permanent magnet thin-film motors have extremely high ...
