Abstract The utility model discloses a bipolar three-phase asynchronous motor, which comprises a stator core and stator windings that are wound in stator grooves, wherein the stator windings are formed in a double-layer overlapping winding way, the number of parallel circuits is 2, the number of the stator grooves is 18 or 30 or 42, the number of one-pole and one-phase grooves is odd number such as 3 or 5 or 7; the pitches of the stator windings are the short pitches; each pole-phase group of conductors of the stator windings are arranged in a same way, and the number of the conductors distributed in each groove in each pole-phase group is not completely same. The bipolar three-phase asynchronous motor realizes the balance of two parallel branch circuits and the balance of three-phase windings, thereby achieving the design requirements that the number of the conductors in each groove is near odd number and the combination property index of an electric motor is ideal.
