Method of controlling a voltage controller for the supply of an induction motor.

摘要

A time sequence of electromotive force amplitudes (e ref) corresponding to a predetermined law for torque variation during transient operating conditions is stored. For this purpose, voltages (W1, W2, W3) applied to the motor (M) and the current flow (I) are determined to derive, at least approximately, the electromotive force (3) generated by the motor. The static switch conduction intervals are acted on to adapt the electromotive force (3) to the stored amplitude (e ref) during the transient operating conditions.
