Abstract Nowadays the electrical machines for electric home appliances require several design points such as compact size, high torque density, high efficiency and noise reduction and so on. In this paper, inner rotor type of IPMSM (Interior Permanent Magnet Synchronous Motor) is designed focusing on improving efficiency and power factor and reducing cogging torque and size to improve characteristics of the conventional motor for washing machine which is outer rotor type of SPMSM (Surface mounted Permanent Magnet Synchronous Motor). Experimental results show that the proposed method is very effective in the characteristic of an IPMSM.
