Embodiment Construction
[0036] Embodiments of the invention include a rotating electrical machine in the form of an electric motor controlled by a switching device. refer to Figure 1 to Figure 12 This embodiment is described.
[0037] As shown, the motor 100 of this embodiment includes a stator assembly 3, a brush assembly 8, a shaft 1 supporting a rotor assembly 2, slip rings 6a and 6b, a flywheel 9, and switching devices 18a and 18b.
[0038] The stator assembly 3 comprises a set of stator poles 4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i, 4j, 4k, 4l and stator coils 5a, 5b, 5c, 5d, 5e, 5f, 5g, 5h, 5i, 5j, 5k, 5l. The stator coils 5a, 5c, 5e, 5g, 5i, 5k have windings designed to supply an excitation current in a clockwise direction, while the stator coils 5b, 5d, 5f, 5h, 5j, 5l have windings designed to supply an excitation current in a counterclockwise direction , so that adjacent poles have opposite magnetic properties. The stator coils are connected in circuit either "parallel" or "series" to each o...
