Abstract

An outer-rotor surface-mounted permanent-magnet synchronous motor for a washing machine with a slinky-laminated stator core is proposed in this study. Material test using the slinky-laminated stator of the motor is conducted to obtain the deteriorated B-H curve and iron loss data. The test is carried out for several levels of excitation field at several frequencies, and the results are compared with those of the conventionally stacked lamination method. In addition, the total iron loss of the motor obtained by the finite element method using the deteriorated material data is compared with the experiment result of the proposed motor.
