METHOD OF VECTOR CONTROL OF THREE-PHASE MACHINE ROTATION SPEED Russian patent published in 2015 - IPC H02P21/00 H02P21/12 H02P27/08 

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering and can be used in the systems of vector control of rotation speed of asynchronous electric motors, synchronous electric motors, double supply machines, including in the systems of sensorless control of rotation speed and DC rotating torque control systems. In the method of vector control of rotation speed of three-phase machine the transformation of phase currents, magnetic flux linkages and voltages of stator into resultant vectors of currents, magnetic flux linkages and voltages of stator and rotor and conversion into their projections to orthogonal axes of coordinates and conversion between stator and rotor vectors are performed as it is specified in patent materials.

EFFECT: improvement of accuracy of rotation speed control and moment of rotation of three-phase car.
