Analysis of Electromagnetic Performance and Principles in Inserted Consequent-Pole Permanent Magnet Synchronous Machines
摘要
Abstract
Based on finite element method, the electromagnetic performances of traditional inserted permanent magnet synchronous machine (IPMSM) and inserted consequent-pole permanent magnet synchronous machine (ICPPMSM) are compared and analyzed. In this paper, a five-phase 20-slot 18-pole ICPPMSM is proposed. Compared with the traditional inserted V-shaped machine with same design parameters, the proposed consequent-pole machine can obviously save the amount of PMs but maintain the comparable output capability, which can improve reliability and save costs. Magnetic circuit and Fourier series analysis are applied to compute fundamental amplitude of airgap flux under each pole. The analytical results demonstrate the configuration of consequent-pole can increase the utilization ratio of PMs. Besides, unlike the traditional IPMSM, the pole-arc of PM-pole in ICPPMSM has wider selection range. By choosing pole-arc of PM-pole and iron-pole, the output performance of ICPPMSM can be further improved. Based on harmonic analysis of induced voltage, the harmonic current injection is more suitable for ICPPMSM. Finally, flux barriers, PM magnetizing length and unequal iron-pole are optimized to acquire better torque quality and flux weakening.关键词
