Article Preview

Abstract:

This paper presents a new structure of field excitation flux switching motor (FEFSM) as an alternative candidate of non-permanent magnet (PM) machine. The rotor is consisted of only stack of iron and hence, it is reliable and appropriate for high speed operation. Initially, the coil arrangement tests are examined to validate the operating principle of the motor and to identify the zero rotor position. Furthermore, the profile of flux linkage, induced voltage, cogging torque, torque and power characteristics are observed based on 2D finite element analysis (FEA). Initial performances show that 8S-12P FEFSM produce torque and power of 8.79Nm and 1.5kW, respectively with low cogging torque and sinusoidal flux waveform. Further design refinement and optimization will be conducted to improve the performances of the motor.
