ABSTRACT:
A drive apparatus includes an electrical motor, a power supply unit, a transmission mechanism, a rail part, and an encapsulating part. The drive apparatus is moveable between a first position and a second position and adjustable in these positions and in any position between these positions. The rail part and the encapsulating part are connected to each other in a heat-conducting connection. A method for operating the drive apparatus includes the steps of changing from one operational mode to another mode and subsequently moving the drive apparatus to a desired position.
