METHOD FOR REGULATING AN ELECTRICAL MOTOR

摘要

The invention relates to a method for regulating a three-phase electrical motor, especially an asynchronous motor with a short-circuit rotor, means for determining the number of revolutions of the electrical motor and the torque required by the electrical motor and a control device. Depending on the number of revolutions and the required torque, a pair of variates is determined in the control device on the basis of the armature current (IQ) generating torque and the field current (ID) producing a magnetic field, which are then supplied to the electric motor for optimized operation in terms of loss. The inventive method is preferably used for operating at least one motor in a vehicle that is driven electrically at least temporarily.
