FIELD: electricity.
SUBSTANCE: magnet core of four-phase thyratron-inductive motor has special configuration according to which angular width of stator poles is equal to angular width of interpolar distance of stator poles, which angular width of rotor poles is equal to angular width interpolar distance of rotor poles; surface of interpolar cavity of rotor poles has shape of bevel semicylinder, which radius is equal to half of linear interpolar distance of rotor poles, radial bevel angle of rotor poles is equal to difference of angular width values of rotor and stator poles; phase windings are star-connected, due to current feedback and frequency-current regulation method control loop allows formation of phase currents in one direction, which contain zero and first harmonics and their amplitude can be regulated by means of inverter consisting of two half-bridge circuits.
EFFECT: reduction of torque pulsation for inductor motor, reduction of its cost due to reduction in number of power semiconductors for inverter included into design of this motor.
