Abstract
An assembly for transferring current comprises at least one electrically conductive slip ring; at least one electrically conductive brush for supplying current to the at least one slip ring; and an electric or pressure actuator driven vibration source for changing the position of the brush with respect to the slip ring. If desired, brush current can shared by using inductance variations or by selective coupling of rotor windings to the slip rings.
Claims11
An assembly for transferring current, the assembly comprising:
- a rotor shaft;
- a rotor coupled to the rotor shaft;
- a plurality of rotor winding regions each including respective rotor windings wound through the rotor;
- a plurality of electrically conductive slip rings coupled to the rotor shaft;
- rotor winding leads coupling the rotor windings to the slip rings, at least a number of the rotor winding leads coupled directly to respective ones of the slip rings.
A method for fabricating an assembly for transferring current, the method comprising:
- providing a rotor coupled to a rotor shaft and having a plurality of rotor winding regions each including respective rotor windings wound through the rotor, and a plurality of electrically conductive slip rings coupled to the rotor shaft;
- and
- coupling at least a number of rotor winding leads from the rotor windings directly to respective ones of the slip rings.
