ABSTRACT:
A method for generating amplitude-coupled voltages for driving a multiple-winding electric motor using tapped voltages which correspond to the values of at least one predetermined curve configuration and using amplitude-coupled output voltages having a progression determined by time-controlled switching of the tapped voltages according to at least one temporal function includes an improvement wherein the tapped voltages have a progression, and the tapped voltages are controlled in such a way that the motor receives voltages having a first curve configuration during a start-up phase and voltages having a second curve configuration during normal operation.
