Applying FEA for Designing a High Efficiency 2.2 kW, 2p = 4 Line Start Permanent Magnet Synchronous Motor
摘要
Line start permanent magnet synchronous motors with direct starting capability have been proven to have high efficiency, high power factor. These motors can be a partial substitute for the widely used squirrel cage induction motors. In terms of construction, the motor uses permanent magnets, and these magnet bars are surface mounted or inserted in the rotor steel core. However, the operating parameters of the motor depend greatly on the motor's structure, particularly the rotor configuration and the size of the permanent magnet rods. To design a 2.2 kW, 2p = 4 motor with high efficiency and self starting capability, the paper focus on using finite element method analysis software to simulate the motor's characteristics and calculate the performance parameters during an operation. From the simulation results, the paper analyzes and selects the appropriate permanent magnet dimensions in the motor design.
