<p>The invention can be used in electrical engineering, specifically in direct current (d.c.) machines, and in any other technical field in which electrical drives and generators are used. In essence, the invention lies in the fact that the d.c. electrical machine comprises a multipole stator whose body can be connected in the horizontal plane, has apertures for mounting permanent magnets (7) and channels in its end faces cut along air gaps in the plane parallel to the magnet system whose elements are accommodated in the housing and are identical in both halves. The elements of the system have permanent magnets (7), a discontinuous magnetic circuit (6) and lateral magnetic circuits with brush holders (12) and brushes (13), as well as a rotor with armature discs (14). The lateral magnetic circuits comprise two parts, namely, a discontinuous part (8) which is contiguous with the magnets (7) and mounted in the end face channels (10, 11), and a continuous part (9). The discs are detachable. The continuous part (9) is stepped, the step dimensions being alternately equal to and different from that of the discontinuous section (8). The permanent magnets (7) are configured to one side of the plane of the armature disc, while the rotor has additional armature discs and additional discontinuous magnetic circuits. Also proposed are variants of the rotor shaft attachment.</p> |
