FIELD: physics.
SUBSTANCE: invention may be used during the production of asynchronous motors. The bipolar winding of the asynchronous motor contains 6 coil groups of three concentrically installed coils in a group, with a coil pitch of each coil group 1-18, 2-17. According to this invention, the third coil of each coil group has a pitch 4-15.
EFFECT: enhancement of magnetic field form and asynchronous motor performance.
