SYNCHRONOUS ELECTRIC MOTOR WITH ANISOTROPIC MAGNETIC CONDUCTIVITY OF THE ROTOR Russian patent published in 2018 - IPC H02K1/24 H02K19/14 H02K19/20 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to synchronous reactive electric motors. Synchronous motor comprises a stator with a magnetic core and windings, bearing shields and a cylindrical rotor consisting of a rotor shaft, fastening studs and a magnetic circuit of a rotor recruited from sheets of a ferromagnetic material with gaps spaced by insulation and batching performed along the axis of the shaft of the machine. Rotor contains conductive non-magnetic buses, the number of which is equal to the number of poles of the motor. Rotor shaft is made of conductive non-magnetic material. Insulation between the sheets is made of a non-conductive non-magnetic material. Fastening of the rotor pole package to the shaft is carried out by current-conducting non-magnetic studs, one end of the pin being screwed into the rotor shaft, and the other, by means of a conductive non-magnetic nut and a conductive non-magnetic bus located throughout the volume in the fixing recesses of the sheets of the pole pack, presses the parcel of the rotor pole to the shaft.

EFFECT: increasing the starting torque, providing the possibility of reversing, reducing the pulsation of the electromagnetic moment, as well as simplifying the design and manufacturing technology of the rotor.
