Zusammenfassung:	The invention concerns a drive unit (22) for driving a motor. the drive unit has a component assembly (1A, 1B) comprising a main circuit board (2) having a component side (2A) and a solder side (2B), one or more main circuit conductors (4A, 4B) formed in at least one layer of the main circuit board, a power component module (5) including one or more power components (6A, 6B), the power component module (5) having electrical connection terminals (8) for connecting the power component(s) (6A, 6B) to the one or more main circuit conductors (4A, 4B) of the main circuit board (2) and a cooling plate (9) coupled to the power component(s) (6A, 6B) in a manner enabling transfer of heat from the power component(s) (6A, 6B) to the cooling plate (9). The power component module (5) is mounted to the component side (2A) of the main circuit board (2). The component assembly (1A, 1B) further comprises a heat sink (10) mounted on the cooling plate (9) and a fan (11) mounted on the heat sink (10).
