摘要： A direct-current electric motor, in particular with small dimensions, comprises a shaft, a winding former, a commutator having a plurality of commutator wires, and an air-cored external rotor winding with a plurality of winding connections. The external rotor winding is connected to the shaft, such that they rotate together, at one end via the winding former. In this case, the winding former represents a load-bearing component. The external rotor winding is furthermore electrically connected to the commutator. In the case of a direct-current electric motor which furthermore has a printed circuit board, the invention provides that the winding former is replaced by the printed circuit board as a load-bearing component composed of a glass-fibre-reinforced thermosetting plastic, wherein the printed circuit board is formed from at least one layer and is connected to the shaft via a metal hub. Alternatively, the invention provides for the winding former to be a metal plate which has a central hole for the connection to the shaft, an isolation ring composed of plastic or ceramic is provided on the external circumference of the metal plate, for electrical isolation from the external rotor winding. The invention also relates to corresponding production methods.
