Enhanced quadrupole high-speed synchronous motor rotor damping structure

Abstract

The invention provides a quadrupole high-speed synchronous motor damping structure solution, which not only solves the defect of poor starting performance of a quadrupole high-speed synchronous motorwithout a damping structure, but also solves the problem of high manufacturing and mounting cost of a traditional full-circle damping ring. The damping structure has the advantages of reducing the copper and iron consumption of the motor and improving the material utilization rate on the premise of ensuring the starting performance of the motor; and simple structure and convenient installation areachieved.

Description

technical field [0001] The invention relates to an enhanced rotor damping structure of a four-pole high-speed synchronous motor, which is usually used in the rotor damping structure of a four-pole synchronous motor rotating at high speed. Background technique [0002] Most of the existing four-pole high-speed synchronous motors adopt a non-damping structure or a full-circle damping structure. The former has poor starting performance, and the latter must be protected by an integrally forged steel retaining ring to prevent its deformation due to the heavy weight of the ring body and the large centrifugal force. High cost and difficult processing.

[0003] The invention provides an enhanced rotor damping structure of a four-pole high-speed synchronous motor, which not only solves the defect of poor starting performance of a four-pole high-speed synchronous motor with no damping structure, but also solves the problem of high manufacturing and installation costs of the traditional full-circle damping ring

In order to solve the problem of excessive contact resistance between the end face of the pole shoe and the damping ring, a layer of silver gasket is placed between the two, and at the same time, silver soldering is performed on the contact parts of the damping ring and the end face of the pole shoe, and between the damping ring and the end face of the yoke , so that the two are in close contact, improving the structural stability
