Abstract

See full text

The DC electric motor has a stator which comprises a permanent magnet with a number p of pole pairs, and has a rotor which can rotate in relation to the stator and has a hollow-cylindrical iron-free winding with a geometric axis and a number Q of sub-coils, and a collector with a number K of collector segments, wherein the sub-coils are arranged distributed over the periphery of the rotor. The brush-commutated DC electric motor furthermore has at least one pair of brushes which are in contact with the collector and by means of which the sub-coils are energized. The arrangement of the brushes and the interconnection of the sub-coils are selected in such a way that in each case a number n≥2 of sub-coils, which are each arranged offset by 360°/n in a rotationally symmetrical manner with respect to the axis of the rotor, are always supplied with the same current at the same time.
