Performance improvement of induction motor by press molded SMC core

In this paper, the performance improvement of an induction motor of which stator core is made of molded SMC (Soft Magnetic Composite) is presented. By using SMC, 3D shaped core is easily constructed. The teeth of the stator core extended in order to enlarge the pole surface area in the same outer dimension of the motor. In this presentation, the motor performance of the motor using the core made by mold process will be presented. The mold process decreases iron loss which is caused by the heat at the machining of bulk SMC. This 3D shape increases output power, Therefore, the efficiency improves, and the maximum output power increases at the same external dimension of the motor.
