摘要：
本发明关于一种用于驱动电机的驱动单元(22)。该驱动单元具有包括主电路板(2)的部件组件(1A，1B)，主电路板(2)具有部件侧(2A)和焊接侧(2B)，形成在主电路板的至少一个层中的一个或多个主电路导体(4A，4B)，功率部件模块(5)包括一个或多个功率部件(6A，6B)，功率部件模块(5)具有用于将功率部件(6A，6B)连接到主电路板(2)的一个或多个主电路导体(4A，4B)的电连接端子(8)以及冷却板(9)，冷却板(9)以使能从功率部件(6A，6B)向冷却板(9)的传热的方式耦合到功率部件(6A，6B)。功率部件模块(5)安装到主电路板(2)的部件侧(2A)。部件组件(1A，1B)进一步包括安装在冷却板(9)上的热沉(10)和安装在热沉(10)上的风扇(11)。
摘要（英）：

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).
