Method and device for regulating a synchronous machine excited by permanent magnet with reduced power oscillations in the upper range of number of revolutions.

摘要

Method for regulating based on the field of a synchronous machine excited by permanent magnet with the following process steps: - establishment of a phase voltage component (ud) and a component transverse voltage (uq) of the control voltage and - transformation component established longitudinal tension and component cross-tensioned in driving pulses for PM synchronous machine, wherein - in a range of speed under transforming component established longitudinal tension and component cross-tensioned in the driving pulses for the synchronous machine is performed using a vibrator pulse (7) and - in a range of high rotational speed is carried out with use of a switching mechanism blocks (21) or a corresponding software program functionally to a switching mechanism in blocks, depending on the nominal angle (?) between the polar axis of the rotor and the indicator space nominal stator voltage.
