DRIVE DEVICE FOR A DOOR

摘要

The invention relates to a drive device for a door, which comprises a drive motor (9) with a rotor (15, 16, 30) and with a first coil (12), whereby the coil (12) is connected to a power element (19) via connecting lines (17). In addition, a control device (28) and a transmission device for transmitting the rotary motion of the rotor (15, 16, 30) into an opening motion or closing motion of the door are provided. The drive motor (9) also comprises a second coil (13), which is connected to a separate power element (22) via connecting lines (18). This enables an emergency operation (battery) (23) of the drive device to be maintained via the second coil (13) and the separate power element (22).
