Abstract

This paper presents high efficiency IPMSM design for compressor of refrigerator having main operation speed of 1800rpm and 3600rpm. The characteristics of IPMSM greatly vary according to back-EMF and inductance. Therefor the design is to estimate the range of back-EMF and inductance satisfying the requirements of IPMSM in the initial design. Thereafter the optimization is performed to consider magnetic saturation and reduce torque ripple. In the end the validity of the design process proposed in this paper is verified by test.
