Abstract |
This paper deals with the design of BLOC motor replacing ferrite magnet with rare earth magnet Electric machinery system using ferrite magnet motor is already widespread in large numbers, Electrical appliance makers have a tendency to adhere to existing system using ferrite magnet motors because of redesigning the whole system This paper designs the rare earth magnet motor untouching the external system dimension and motor outer size. To do the design simply, finite element package is used iteratively. To reduce the cogging torque effect and magnetic saturation, stator yoke shape and the groove of the end face of yoke are redesigned. |
