Description

The utility model relates to the field of electrical engineering, in particular to electric motors with a phase rotor, and can be used as power actuators for various electric drives of industrial mechanisms, etc. Known three-phase electric motors with a phase rotor type MTF, MTN, MTM, consisting of a stator and a rotor with windings, the disadvantage of this device of electric motors is not high efficiency due to irrational and incomplete use of the areas of the magnetic circuit of the stator and rotor of the electric motor, the closest in technical essence to the claimed The prototype of the electric motor MTN 012-6U1, patent RU47588U1, publication 08.27.2005 (“electric machines” edited by I.A. Danilov, K.V. Lototsky, “Handbook of Electrical Engineering” A.A. Ivanov, “Handbook of the wrapper electrical machines "A.S. Kokorev).

The technical result of increasing the efficiency of the proposed device in electric motors with a phase rotor is achieved due to the possibility of rational placement of distributed two-layer windings in the stator and rotor, where (q) the number of slots per pole and phase increases by 2 times, which contributes to an increase in the number of winding sections by 2 times in stator and rotor and their placement in the grooves, the pitch (y) of the windings is different, due to which the highest value of the winding coefficients in the stator and rotor is achieved, an increase in the areas covered by more evenly distributed magnetic fluxes of the stator and rotor, which gives a maximum connection of the magnetic fields of the stator and rotor , in turn, the ability to bring the shape of the EMF curve as close as possible to a sinusoid to obtain the highest value of current in the rotor windings interacting with the stator magnetic field for rotation, which differs from the prototype.
