INDUCTOR-TYPE VALVE MOTOR WITH BUILT-IN MAGNETIC REDUCER Russian patent published in 2024 - IPC H02K49/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to combined electric machines having properties of magnetoelectric AC motors and magnetic reducers. Inductor-type valve motor with built-in magnetic reducer comprises three-phase low-pole winding on fixed stator with number of pairs of poles p₁ from 1 to 4, powered by frequency converter and laid in open slots with number of teeth (slots) Z₃, low-speed modulator with number of ferromagnetic rods Z, high-speed rotor with a laminated core, on the outer surface of which there are open slots (teeth) with number Z₂ = Z-Z₃ = p₁, according to the invention, the rotor and stator are made without permanent magnets, there is a DC excitation winding on the end shield, the motor has one output shaft coupled with a low-speed modulator.

EFFECT: providing the possibility of short-term forcing of electromagnetic torque on the motor shaft due to short-term increase of current both in the stator winding and in the DC excitation winding.
