ABSTRACT:
A method, apparatus and system for selectably directing power signals to coils of active field pole members in brushless electrodynamic machinery are disclosed. In one embodiment, a field pole commutator includes a power transfer region configured to transfer at least a first power signal and second power signal to the coils. It also includes a first power region and a second power region configured to provide the first power signal and the second power signal, respectively, to the power transfer region. The first power region and the second power region each are configured to rotate together with the power transfer region about an axis of rotation. In one embodiment, the field pole commutator is implemented in a brushless direct current (“DC”) current motor, which includes a rotor having permanent magnets and a plurality of active field pole members. Each active field pole member has one or more coils wound about the periphery of field pole members to form said plurality of active field pole members. In a specific embodiment, permanent magnets of the rotor include either conical magnets or cylindrical magnets, or both.
