Method for control or regulation of an electric motor and arrangement for executing such a method

摘要

The device has a pulse width modulator (24), for variation of the pulse width ratio in response to a supplied setting signal (Uin) within a defined range, for corresponding operation of a semiconductor switch (14) in series with the drive motor (12). An over-ride device is controlled in dependence on the detected motor parameters for over-riding the function of the setting signal in a defined parameter range.
