MULTIPHASE PERMANENT MAGNET SYNCHRONOUS MOTOR DRIVE A COMPARATIVE STUDY

Low frequency oscillations, high torque pulsation are a major disadvantage of three phase permanent-magnet motor configurations. Choosing the proper number of stator slots and winding distribution as well as increasing number of phases are among the possible solutions for reducing torque pulsation. In this research work, we propose to investigate the comparative performance of a Multi-Phase PMSM with different rotor topologies by Finite Element Analysis (FEA), Modeling & Simulation using MATLAB. This will be verified by practical fabrication and testing. Also our researchdevelops a guideline regarding selection of appropriate rotor construction of PMSM to meet different types of load characteristics. Some of the following issues shall be addressed while doing so. This type of work is not found in literature. It will help in selection of appropriate topology of the machine for various applications.
