Abstract
Among all types of electrical motors, Permanent Magnet Synchronous Motor (PMSM) is the most reliable and efficient motors in industrial applications. It is widely used in industries, home application, automotive and aircraft, due to its low maintenance, high efficiency, good dynamic performance and high torque density. This project investigates the influence of the various type of winding configuration and different magnetization patterns in the performance of a five-phase PMSM. Three types of magnetization patterns such as radial magnetization, parallel magnetization, and multi-segmented Halbach magnetization are applied to the 10-slot/4-pole PMSM during open-circuit and on-load conditions. A 2D finite element method (FEM) is intensively used in this investigation to model and predict the electromagnetic characteristics and performance of the PMSM. The detailed finite-element analysis (FEA) results on the cogging torque, phase back-EMF, air gap flux density, electromagnetic torque, unbalanced magnetic pull and output torque, are analyzed. The phase back-EMF of the motor is computed further into its harmonic distortions. Further, the skewing method for minimization of cogging torque of PMSM is proposed. As a result, the PMSMs with double layer distributed winding with parallel magnetization gives the best motor performance in terms of high fundamental phase back-EMF, low total harmonic distortion, low peak cogging torque, low UMP and high average electromagnetic torque. Due to this, the PMSM has potential to provide the cost savings for the electric vehicle with a compact winding configuration in multi-phase motors, which is capable of providing smaller magnet volume with a high-performance motor.
