Abstract
The method for activating an asynchronous motor comprising at least two windings is provided, in order, for the purpose of a change in the rotational speed, to connect a first winding and at least one second winding by way of at least two electronic switches. On switching, both switches are opened for one or more time intervals in order to avoid current peaks.
