Abstract

The commutator electric motor comprises a stator winding (7), a tacho-generator winding (9) and an annular permanent magnet (6) of a rotor. The permanent magnet (6) is so magnetized in an axial direction that it has two sets of alternating opposite poles (13, 14). The poles (13) of the first set are defined on the face surface of the permanent magnet and form a main magnetic flux which acts on the stator winding (7). The poles (14) of the other set are defined on its lateral cylindrical surface and form the magnetic flux acting on the tacho-generator winding (9), which is arranged in front of the lateral surface of the tacho-generator.
