Test Results of SMC Cores as Some Types of Motor Cores
Recently, SMC(Soft Magnetic Composite) materials were studied for their applications in many fields. We have developed a superior SMC for use as motor cores and are studying their applying effects . It shows almost the same motor output power as laminated Si-steels of 0.35mm in thickness, although core loss of SMC is about 1.5 times that of the laminations. As shown in the results, the SMC motor core is sufficient for real use as a motor core. Furthermore, a 3-D shaped motor core made of SMC can improve approximately 20% of the output compared with the same size motor made of laminations.
