Design and analysis of a permanent magnet motor with SMC core for driving dishwasher pump

This paper presents the development of a permanent magnet motor with soft magnetic composite (SMC) stator core for driving a dishwasher pump. The unique properties of the SMC, such as 3D magnetic isotropy and molding production technique, have been taken into account in the design. 3D magnetic field finite element analysis is carried out to accurately compute the motor parameters and an equivalent electrical circuit is derived to predict the motor performance. Analysis results show that the developed motor is appropriate. © 2009 IEEE
