ABSTRACT:
A DC magnetic motor includes first and second stator plates each equipped with first and second commutating rings and four ferromagnetic bodies (e.g. steel) or permanent magnets positioned in quadrature with angularly adjacent permanent magnets having opposite polarities. A pair of rotor plates are fixedly coupled to a central shaft which is mounted for rotation in the stator plates. The rotor plates house a plurality of electromagnets which are energized by a plurality of pairs of brushes which are coupled to the rotor plates and slide along the commutating rings. The segments of the commutating rings are energized and organized such that each electromagnet will be attracted to the next ferromagnetic body. The magnetic field in the electromagnets is collapsed by gaps between segments of the rings during the time in which each electromagnet is rotating by the ferromagnetic body to which it was attracted after which the magnetic field in the electromagnet is reversed.
