摘要： A brushless dc external-rotor motor having a hollow cylindrical heat sink fastened to the peripheral border region of a printed circuit board. Power semiconductors are arranged on an inner cylinder wall of the heat sink in a heat conducting manner, and the cylinder wall forms part of the peripheral border of the stator flange in the motor. A connector fastens Hall generator(s) on the circuit board and provides the electrical connection with the circuit board. The connector can be soldered along with all other electronic components in a joint soldering process, wherein a subassembly of a preassembled circuit board and a heat sink fastened to its periphery and carrying the power semiconductors passes through a solder bath to solder all components in a single soldering process. It is subsequently necessary only to plug the Hall generator or generators onto the connector or connectors soldered onto the circuit board. The connector can include individual contact tubes, which are soldered in the circuit board and into which the connection pins of a respective Hall generator can be plugged.
