Abstract
A method controls a motor, especially for opening and closing a door. The motor is controlled by a pulse width-modulated switching signal that is divided into a specifiable number of pulse width-modulated control signals for actuating a bridge circuit to a corresponding number of functional channels. The functional channels are switched off independently from each other by at least one or more switch-off signals on at least one switching circuit of a number of independent switching circuits corresponding to the number of functional channels.
