| 摘要 |
The invention relates to an inverter motor comprising a motor (2) and an inverter (4), wherein components of inverter electronics are disposed on a circuit board such that the lossy components are thermally conductively connected to a heat sink (8) designed as a cover of an inverter housing made of thermally insulating plastic, wherein said inverter housing made of thermally insulating plastic is axially mounted on a B-side of the motor (2). According to the invention, the circuit board (14) is divided into a plurality of circuit board elements edged relative to each other such that circuit board segments having components having lower power loss are each thermally conductively connected to a wall of an inverter housing wall (6), and that a central circuit board segment having lossy components is thermally conductively connected to a heat sink made of thermally conductive plastic, and the motor (2) has a bulkhead (16) made of thermally insulating material on the B side thereof, whereon a connector strip (18) is disposed. The result is a compact, fanless inverter motor.
