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).
