VALVE REACTIVE INDUCTOR MOTOR Russian patent published in 2009 - IPC H02K19/06 H02K19/10 

FIELD: electrics.

SUBSTANCE: invention can be applied in electric wires with high requirements to torque pulsation, vibration and noise level and allows power supply to motors from standard bridge converters produced in series. Valve reactive inductor motor includes cogged stator with cogs distributed regularly along perimetre, with cog number Z₁ multiple of 2m (Z₁=k×2m, where k=2, 3, 4, …), and cogged rotor without windings with cog number Z₂=Z₁±k. Stator cogs bear two focused m-phase windings with phase coils positioned and wound on cogs so as magnetomotive force directions of same phases in one coil are the same (from stator to rotor or from rotor to stator). Positive effect of invention includes torque pulsation reduction due to the use of two m-phase windings and is achieved by spatial shift of same phases in each winding by 180 electric grades against each other and by power supply to each winding from voltage impulses of equal value and duration with time shift angles of 180 electric grades between same phases of different windings. Windings can combine in m-beam "star" (with neutral or without it at m >1) or in m-side polygon at m>1, and can gain power from m-phase bridge inverter using diodes in winding phases for positive and negative voltage impulse distribution between parallel same phases of two windings.

EFFECT: reduced torque pulsation.
