MOTOR AND ROTOR FOR DYNAMO-ELECTRIC MACHINE

摘要

A motor (M) comprises first and second stators (12L, 12R) on the outside forming a rotating field, an outer rotor (13) arranged on the inside thereof and having first and second induction magnetic poles (38L, 38R), and an inner rotor (14) arranged on the inside thereof and having first and second permanent magnets (52L, 52R). Since the phases of the first and second induction magnetic poles (38L, 38R) of the outer rotor (13) are shifted from each other by one half of a predetermined pitch, and the phases of the first and second permanent magnets (52L, 52R) of the inner rotor (14)are shifted from each other by a predetermined pitch, the phases and the polarities of the first and second stators (12L, 12R) facing the first induction magnetic pole (38L) and the second induction magnetic pole (38R) can be made identical and thereby the structure of the first and second stators (12L, 12R) can be simplified.
