Static Analysis of 18-Slot/16-Pole Permanent Magnet Synchronous Motor Using FEA

This paper presents the static analysis of 18-slot/16-pole Permanent Magnet Synchronous Motor (PMSM) using Finite Element Analysis. The motor is designed from half model of rotor and stator. Then it is built until becoming a complete motor. The stator and rotor core are made from silicon steel laminations, and Neodymium magnets is used for permanent magnet and located at the rotor surface. A 120 turns of coil per phase is wounded around the 18-slot of the motor. It consists of winding for phase A, B, and C respectively. The phase windings are not supplied and the rotor is moved manually. Then the motor flux linkage, induced backelectromagnetic force, and cogging torque are simulated and results show the output performing correctly with the mathematical method. The developed motor can be improved by adjusting the stator tooth width.
