REGULATION OF AND REGULATOR FOR A PERMANENT MAGNET SYNCHRONOUS MOTOR

摘要

In the regulation system of the invention, the longitudinal current id in a permanent magnet synchronous motor is adjusted to zero. In the regulation, the third harmonic of the control signal can be added to the result of a coordinate system transformation of the control voltages. In a regulator for a permanent magnet synchronous motor, a 3-phase reference for the motor supply voltage is formed from the uq and ud voltages by transforming them to produce components corresponding to each phase and by combining the components for each phase.
