Abstract

The invention provides an assembly and disassembly device for the stator and rotor of a radial permanent magnet motor. The fixed platform is provided with a positioning through hole b, and the guide rails are vertically fixed on the upper end of the fixed platform. The center of each guide rail reaches the positioning through hole b The distance between the center of the circle is the same, the extension shaft positioning sleeve is installed under the fixed platform, the elevator is set under the extension shaft positioning sleeve, the extension shaft is connected to the upper end of the elevator, and the extension shaft passes through the extension shaft positioning sleeve and the positioning through hole b It can frictionally slide up and down in the extension shaft positioning sleeve. The rotor positioning plate is provided with a guide rail sleeve. The guide rail passes through the guide rail sleeve and is connected with the rotor positioning plate. The sleeve, the positioning through hole b and the positioning through hole d are coaxial. The assembly and disassembly device of the radial permanent magnet motor stator and rotor has simple structure and convenient operation, and solves the problem of manual assembly and disassembly of the radial permanent magnet motor stator and rotor.

Description

technical field [0001] The invention belongs to the technical field of permanent magnet motors, and mainly relates to an assembly and disassembly device for a stator and rotor of a radial permanent magnet motor. Background technique [0002] Nowadays, the development of energy-saving, environmental protection, green and low-carbon economy has been highly valued by the country and people. The national plan clearly puts forward the requirements for economic development focusing on environmental protection. Motors are high-energy-consuming power equipment with a large number of applications and a wide range of applications. The power consumption of motors in my country accounts for about 70% of the total industrial power consumption. Therefore, the promotion of motor energy saving has important economic and social benefits. [0003] Compared with asynchronous motors, permanent magnet motors have the following advantages: high efficiency at light load and full load, can meet th...
