<p>The drive has a controller (2) and a drive motor (10) supplied with electrical energy by an electrical supply (1). The controller separates the door drive from the electrical supply in an operating mode, and an electrical energy storage (3) supplies the electrical energy. The controller connects the door drive with the electrical supply in another operating mode, and is switched into the latter operating mode when the drive motor is moved. The energy storage is supercharged in the latter operating mode.</p> |
