Abstract

The invention relates to a rotor assembling deformation suppression device and method for low-speed large-torque permanent magnet motors. The device comprises a rack main body, excircle pinch rollers,axial pinch rollers and excircle pressing plates; support arms which are bent downwards are arranged on two sides of the rack main body; the screw at the lower end of one or more excircle pinch rollers passes through the rack main body and is in threaded connection with the rack main body; one or more axial pinch rollers pass through the support arm on each side and are in threaded connection with the support arm; and the excircle pressing plates are arranged at the lower ends of the excircle pinch rollers. The method comprises the following steps of: mounting a rack on a rotor core main bodyand carrying out positioning after adjusting the rack to a proper size; carrying out axial compression; compressing an excircle magnetic separation bridge of the rotor core main body; and loading a permanent magnet. The device and method provided by the invention can solve the problem that the magnetic separation bridges of low-speed large-torque permanent magnet motors undergo damage and plasticdeformation in the rotor assembling process.

Description

technical field [0001] The invention relates to a device and method for suppressing assembly deformation of a rotor of a low-speed high-torque permanent magnet synchronous motor. Background technique [0002] During the assembly process of the permanent magnet, due to the certain friction and suction between the permanent magnet and the groove, it is necessary to give the permanent magnet a certain force to make it enter the designated position smoothly. If the force is not applied properly, it will easily cause such figure 1 with figure 2 The shown magnetic isolation bridge a101 and magnetic isolation bridge b 102 are destroyed, as image 3 The magnetic isolation bridge d 104 shown is broken and causes outward plastic deformation of the rotor. Therefore, it is very necessary to invent a device and an assembly method for a low-speed high-torque permanent magnet motor to suppress the assembly deformation of the rotor. Contents of the invention [0003] purpose of invent...
