Performance improvement of induction motor made of three dimensional shaped SMC core

In this paper, performance improvement of an induction motor is discussed. Soft Magnetic Composite (SMC) is used as an iron core of the motor. The stator core is divided into 48 parts. The shape of stator core has 3D shape. Conventionally, the core is consisted by 2D laminated core by same punched steel. In his study, the teeth of the stator extended in order to enlarge the pole surface area. Experimental motor shows that the efficiency improves, and maximum output power increases at the same external volume of the motor.
