Analysis and Calculation of Electromagnetic Performance of High Speed Permanent Magnet Synchronous Motor

Abstract

Abstract:

With the rapid development of industrial technology, more and more high-speed machines need high-speed motor as drive equipment. In this paper, the key technologies of high-speed permanent magnet motor are analyzed, an electromagnetic design of 330kW, 25 000r/m permanent magnet motor is carried on,a simple and reliable structure are proposed. Then, the finite element simulation technology is used to calculate the no-load and load characteristic of the motor. The result verifies the rationality of the design.

Key words: High speed permanent magnet motor, electromagnetic design, ventilation and cooling, finite element calculation
