FIELD: electricity.
SUBSTANCE: stator winding is made in the form of two sinusoidally distributed n-phase windings, one of which has an even number of pairs of poles, the second one is an odd number of pairs of poles, near to even, the rotor is made of two parts, forming a cylinder one of which is made in the form of a sector with an angle of 235-245° and made of a set of isolated electrical steel plates, and the other part is made of non-magnetic material, the stator windings are connected in parallel and to the n-phase network.
EFFECT: obtaining the rotor speed of the motor, which is twice the frequency of the alternating current of the mains.
