INDUCTOR-TYPE INVERTED MOTOR WITH UNIPOLAR EXCITATION Russian patent published in 2024 - IPC H02K16/04 H02K19/06 H02K19/12 

FIELD: electrical engineering.

SUBSTANCE: invention can be used in production of high-efficiency inverted motors. Inductor-type inverted motor with unipolar excitation contains tooth windings on two fixed disk stator cores with number of pairs of poles p₁ each, powered by frequency converter. Rotor is fixed on a non-magnetic bushing put on the motor shaft, and contains longitudinally laminated axial teeth with number Z₂=p₁, fixed on outer surface of non-magnetic bushing and separated from each other by through slots. On the end shields, DC excitation coils are fixed, which create a unipolar magnetic flux, which is closed through the end shields, stator cores and the rotor, axial working air gaps and motor shaft.

EFFECT: provision of possibility of short-term forcing of electromagnetic torque on motor shaft both due to short increase of current in stator windings, and in coils exciting unipolar magnetic field.
