Cogging torque is a common design issue in Permanent Magnet Synchronous Machines (PMSMs). Altering the magnet shape is one of the solutions in reducing the cogging torque. This paper addresses the variation in the rotor magnet pole arc which would affect the cogging torque of the external rotor permanent magnet synchronous motor (ERPMSM). Analytical calculations to design a three-phase, 12slot/8pole...
This paper discusses the rotating analysis for 18-slot/16-pole Permanent Magnet Synchronous Motor (PMSM) using Finite Element Method. The PMSM is applied for Light Electric Vehicle (LEV) which has about 200 kg net mass and maximum velocity of 30 km/h. The motor is located in the wheels of the LEV. The motor is built using three main components i.e. laminated steel iron, coils, and Neodymium-Iron-Boron...
