ABSTRACT:
A collectorless direct-current motor with a stator mounted on a motor flange and a rotor mounted so that it can rotate on a shaft, in which case power semiconductors for the purpose of commutating the currents of the stator are attached to parts of the motor for the purpose of dissipating the heat and a circuit board with electronic components is provided for the purpose of controlling the commutation, and the power semiconductors are electrically connected to the circuit board, in which case the power semiconductors (39) are attached to the motor flange (2), preferably the outside (29) thereof, in heat conducting contact.
