METHOD FOR CONTROLLING INDUCTOR MOTOR Russian patent published in 2007 - IPC H02P6/00 H02P25/08 

FIELD: electrical engineering; inductor-motor drives, direct- and alternating-current consists.

SUBSTANCE: proposed method for controlling inductor motor includes power voltage supply to motor operating phase being de-energized in beginning of each of m intervals between 0 and 180 deg. and its pick-off as soon as current of this phase is brought to desired value. As soon as torque set up by this phase or that produced by operating phase is brought to desired value or to higher value, motor phase brought out of operation is not energized, and voltage is applied to that brought in operation and picked off as soon as current through this phase acquires desired constant value. Supply voltage is applied to motor operating phase in beginning of current interval and picked off as soon as current through this phase is brought to desired value. Electromagnetic torque due to phase brought in operation, that due to phase brought out of operation, desired current through this phase, and electromagnetic torque due to operating phase are calculated using formulas of invention specification. Fluctuations of traction three-phase reluctance inductor motor torque are reduced from 15 to 1%.

EFFECT: reduced torque fluctuations.
