摘要

Various electric propulsion systems are used in the industrial field. Recently, research focused on permanent magnet synchronous motors (PMSMs) because of their several advantages. One advantage is high torque output; thus, this characteristic is suitable for application in a direct drive. The application to electric ships requires motors with the high torque at low speed. A transverse flux-type PMSM was investigated previously. However, this motor had two issues. One was high cogging torque. The other was eddy current loss in the disk. Thus, the authors propose a new design for a PMSM that reduces the cogging torque by employing a pole-core combination. In addition the material of the disk has been changed to reduce the eddy current loss. Finally, the characteristics of the newest prototype motor are explained.
