Abstract

Abstract:

The line-start permanent magnet synchronous motor (LSPMSM) with high efficiency, high power factor and wide range of economic operation has a wide range of applications in the textile, oil field industries . In this paper, a 6 poles, 22 kW LSPMSM ’structure was optimized based on Rmxprt and Maxwell, improved the power factor and efficiency, decreased the cogging torque of the motor; And the finite element analysis were established of the no-load and rated load cases running conditions, the simulation results show that the optimized motor has a better starting performance, verify the rationality of the electromagnetic design, providing an important basis for the optimization of LSPMSM.

Key words: Line start, permanent magnet synchronous motor, optimization design, cogging torque
