摘要：PROBLEM TO BE SOLVED: To provide a three phase AC motor dissolving unbalance of a characteristic between windings constituting a stator winding even if the axis of a rotor is deviated from that of a stator.SOLUTION: In the three phase AC motor, a plurality of unit windings are arranged circumferentially along the stator at equal intervals. Winding in which one set of unit windings (U1 and U3, for example) in point-symmetric positions are connected in series with the rotation shaft of the motor as a center in the unit windings is set to be partial winding (U1-U3, for example) without connecting all the unit windings corresponding to the respective phases in series. A plurality of the partial windings are connected and a stator windings of the motor are constituted.
