1. Drive device for a sunroof of a motor vehicle, comprising:
- an electric motor, a gearing which is in driven connection with the electric motor, a circuit for triggering the electric motor, and a gear casing for accommodating the gearing;
wherein the gear casing has at least one casing wall of a metallic material with a high thermal conductivity relative to plastic and wherein at least part of the circuit is located adjacent to said at least one casing wall outside of the gear casing with the components of the circuit being in heat exchange contact with said at least one casing wall to dissipate the heat which forms during operation of the circuit to the casing wall.

Abstract
In a drive device, especially for a sliding roof of a motor vehicle, with an electric motor (10), gearing (24) which is driven by the electric motor, and a circuit (22) for triggering the electric motor, the gearing (24) is accommodated in a gear casing (42) with at least one casing wall (50) of high thermal conductivity and at least part of the circuit (22) is located adjacent to this casing wall (50) outside of the gear casing (42). Furthermore, contact (36) is made between the components (44) of the circuit (22) and the casing wall (50) in order to dissipate the heat which forms during operation of the circuit (22) to the casing wall (50).
