    Disc-type motor characterized by increased efficiency. The motor has two parallel spaced stator members (30, 32) each having a flat circular shape and an even plurality of pre-segmented permanent-magnet poles (34) in a circular array thereon, illustratively eight in number. The facing poles of the stator members have opposite polarities. The motor includes a disc rotor (28) made of a non-conducting material rotatably mounted between the two stator members. Conducting wires are wound to form a number of coils (29) in a circular array on each face of the rotor. The number of coils on each rotor face is greater than the number of poles on each stator member, and each coil (29) occupies an arc sector area smaller than the area of each stator pole (34). The coils (29) arrayed on one face of the rotor (28) are angularly offset from the coils on the other face of the rotor. The includes a commutator (44) connected to the rotor (28) which has a number of segments corresponding to the coils of the rotor.@00

    wound on two sides of the disk 7. The winding sections on one side of the disk are offset from the section on the other side of the disk. All sections are wound in the same direction. The number of sections on each side is greater than the number of poles of each stator. Wires are coated with thermoplastic. Each
    A winding section of one side is connected at one end to a collector plate to which one side of the section is connected, located on the other side of the disk. Such a connection circuit eliminates induction in shorted sections, improves switching and improves efficiency. 9 ep f-ly, 3 ill.

    The invention relates to electrical engineering, in particular to electric machines with a disk rotor.
    The purpose of the invention is to increase efficiency.
    Figure 1 shows the axial section of an electromechanical machine; figure 2 - the location of the windings on the disk rotor; on fig.Z - connection of the windings with the collector plates.
    Shaft 1 mounted on bearings 2 and 3 is mounted in the housing of the machine. On shaft 1, there is a sleeve f and half sleeves 5 and 6, which rotate with the shaft. A disk 7 made of a non-magnetic material is placed between the half-sleeves 5 and 6, and the windings 8 are placed on the disk 7. The two stator 9 and 10 are placed parallel to each other on the case. ferrite, and fixed on the plates 12 and 13, made of magnetic conductors. On the surface of the magnets 11 facing the gap, the tips 14 are tapered, tapering towards the gap. On the shaft 1 there is a collector 15, which consists of conductive plates 16. On the rear panel 17, the brush holders 18 of the brushes 19 are fastened. separated by insulating gaskets. A winding 8 is disposed on the disk 7, each winding section being wound in several layers. The winding sections on one side of the disc are offset from the sections on the other side of the disc. All sections are wound in the same position and connected in series. The number of sects; s on each side of the disk is the number of poles P of each stator, therefore the area occupied by the section is smaller than the area of the pole. Wires from which sections are wound are covered with thermoplastic or resin. The wound section may additionally be covered with thermoplastic or resin for durability. The number of plates 16 collector 15 is equal to the number of sections of the winding. Each winding section
    one end with one end attached to the collector plate, to which one side of the section is connected, located on the other side of the disk, etc.
    Thus, the proposed machine is compact, has a small weight, great power, hence increased efficiency. In addition, the machine has a smooth torque response. The proposed winding connection scheme provides improved switching conditions. The exclusion of induction in shorted winding sections makes the life of the brushes extended.
