Abstract
The four-pole synchronous motor comprises a stator core having first magnetic pole cores formed at both ends of a connection body part of crisscrossed connection body parts and second magnetic pole cores formed at both ends of the connection body part. The first magnetic pole cores include magnetic flux acting surface parts extended toward both sides thereof in a circumferential direction. A shape of each magnetic flux acting surface part on one side of a longitudinal centerline of the first magnetic pole cores is different from that on the other side so as to be magnetically asymmetrical with respect to the longitudinal centerline.
