Abstract
An electric direct current motor is disclosed which includes a shaft, a winding support, a collector having several collector wires, and an air-cored outer rotor winding with several winding terminations. The outer rotor winding is at one end connected to the shaft via the winding support in a torque-proof manner, and is electrically connected with the collector. The winding support can be replaced by a printed circuit board as a bearing component of glass-fiber reinforced thermosetting plastics, wherein the printed circuit board includes at least one layer and is connected to the shaft via a metal hub.
