ABSTRACT:
A commutation apparatus drives a brushless motor having a stator equipped with a plurality of coils and a rotor. The commutation apparatus comprises a rotatable commutator shaft, two or more conducting rings carried discretely about the shaft, and two or more conducting segments carried discretely about the shaft at staggered positions along or near a plane perpendicularly intersecting the shaft. Each conducting segment is electrically connected to one of the conducting rings. Two or more electrical source contacts are provided for rotatably connecting a power supply across pairs of the conducting rings. A plurality of electrical load contacts is further provided for sequentially, rotatably connecting the conducting segments to discrete coils of the brushless motor. In particular embodiments of the commutation apparatus, a magnetic coupling is employed for rotatably coupling the commutator shaft to the rotor of the brushless motor, and a pressure-bearing container is provided for rotatably supporting the commutator shaft and the coupling therein.
