    摘要: A current regulation process and device for a three-phase, static-converter-fed, permanently excited synchronous machine with a trapezoidal magnet wheel voltage. A phase angle sensor is mounted on the motor shaft of the machine and is coupled to an evaluating device providing an actual speed of rotation value. Current measurement devices measure the currents to the machine. A current actual value spatial vector is generated from two phase current actual values, which spatial vector is estimated as a function of a calculated normalized magnet wheel voltage, whose rotor flux-oriented current components are supplied to current regulators, which generate a voltage spatial vector. A simple field-oriented current regulation is achieved for a three-phase, static-converter-fed, permanently excited synchronous machine with a smooth torque at low rotation speeds and low intermediary circuit or battery current ripple at high rotation speeds.
