Electrical machine, in particular motor, a direct current, a reversing the direction of rotation, the assembly of such a machine, and means of control switches, and its application to a clutch pilot

摘要

The DC electric machine comprises a rotor equipped with a commutator 4 cooperating with at least two brushes 1, 2 mounted in a stator. The machine includes at least one additional brush 7, 8 capable of cooperating with the commutator and intended to be connected to one of the poles of a DC supply source, whilst at least one of the first brushes 1, 2 is intended to be connected to the other pole of the source, depending on the desired direction of rotation, at least one other of the first brushes 2, 1 remaining isolated from this other pole, so that a single switch means d1, d2 is associated with each of the first brushes 1, 2.
