摘要

The control device uses a sensor (10) for measuring the rotor magnetic field and phase-control (11,12,13) for corresponding phase control of the voltage provided by the AC source (14), for limiting the current in at least one stator winding (5,6) to a given value. Preferably, the polarity of the measured magnetic field and the required direction of rotation of the permanent magnet rotor (9) is used to control the phase-control during the start-up of the motor from standstill.
