BRUSHLESS DC ELECTRICAL GENERATOR

摘要

The present disclosure relates to an apparatus for the generation of a unidirectional electrical signal. The apparatus may include at least one magnet defining a magnetic field, a rotor disc of substantially no magnetic permeability comprising at least one magnetic field interrupter of magnetically permeable material positioned at a first radial distance from a center axis of the rotor disc, the rotor positioned so as to, upon rotation of the rotor disc, cause the at least one interrupter to pass through the magnetic field, and an electrical conductor extending across the magnetic field, whereby as the at least one interrupter passes through the magnetic field, the magnetic field is distorted by the interrupter thereby inducing a unidirectional electric signal in the conductor. The at least one magnet may be an electromagnet or a permanent magnet. The at least one magnetic field interrupter may be made of soft iron.

1. An apparatus for the generation of a unidirectional electrical signal, comprising:
at least one magnet defining a magnetic field; a rotor disc of substantially no magnetic permeability comprising at least one magnetic field interrupter of magnetically permeable material positioned at a first radial distance from a center axis of the rotor disc, the rotor positioned so as to, upon rotation of the rotor disc, cause the at least one interruptor to pass through the magnetic field; and an electrical conductor extending across the magnetic field, whereby as the at least one interrupter passes through the magnetic field, the magnetic field is distorted by the interrupter thereby inducing a unidirectional electric signal in the conductor.
