The portions located on the periphery of the core in the axial direction thereof are substantially parallel to the rotor shaft, and a disc-shaped commutator plate is disposed in at least one of recesses formed at both end surface parts of the core in its axial direction by both end surfaces of the core in its axial direction and with the terminal connections of the windings raised above both end surfaces. The commutator plate is fixedly provided on the rotor shaft so as to be substantially perpendicular thereto. The brushes are each formed of an integral structure consisting of a first spring element in a right-angled U-shape and a second spring element supporting the first spring element approximately at the middle of the parallel arm portions thereof, the open ends of the first spring element forming contact points, and the ends of the second spring element opposite to the above-mentioned supporting ends forming the securing ends therefor.

Abstract: An improved frequency generator is disclosed. The frequency generator includes such a permanent magnet that is magnetized in the direction of the axis of a rotary shaft with which the rotor of the generator is rotated. Between the second magnetic pole side of the permanent magnet and the rotor, there is disposed a flanged cylindrical frame member comprising a flange part and a cylinder part. At the side of the second magnetic pole, the permanent magnet is connected with the flange part of the frame member. The cylinder part of the frame member is arranged so as to surround the circumferential surface of the rotor. The flanged cylindrical frame member disposed in this manner is magnetically conductive so that the area through which the magnetic flux flows between the second magnetic pole side of the permanent magnet and the rotor is effectively increased as compared with the conventional one.

These members are made of oil-containing sintered alloy as a unitary member. The inner cylindrical surface of the bearing part of the stationary field yoke supports a rotary shaft rotatably therein. A motor coil assembly in a shape of cup is fixedly mounted on the rotary shaft. A generator coil assembly is also formed in a shape of cup which has a central opening in the botton wall of the cup. The diameter of the central opening is approximately equal to the outer diameter of the bearing part of the stationary field yoke. The open end of the cup like generator coil assembly is disposed in opposition to the open end of the cup like motor coil assembly and these two open ends in opposition to each other are jointed together with the interposition of an insulating element therebetween so as to form a rotary coil unit which encloses the field part of the field yoke. A commutator for generator is formed in a shape of cylinder the inner diameter of which is larger than the outer diameter of the bearing member of the field yoke and the commutator is secured to the generator coil assembly keeping a spacing between the commutator and the bearing member.
