Abstract

Coil arrangement is one of essential part in electrical machine design that affects the torque performance of the machine. Thus, a new stator slot structure of permanent magnet machine called Independent Coil Excitation Permanent Magnet Motor (ICE-PMM) is introduced. Design and magnetic circuit analysis of ICE-PMM is presented. In addition, qualitative comparisons are made with the other conventional types of Permanent Magnet Machines (PMM) which are Slot-type and Slotless rotor. A brief description on the basic concept of the ICE-PMM motor design along with the Slot-type and Slotless rotor structure are presented. The main objective of this paper is to evaluate PMM type that has better static torque with low cogging between conventional and ICE-PMM. Simulation studies of all three PMM are presented in order to evaluate the feature of its flux distribution, flux linkage, flux flow, cogging and static torque characteristics. In a conclusion, the ICE-PMM could perform better as high static torque PMM with lower cogging compare to the other two conventional types.
