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.
Claims28
An assembly for transferring current, the assembly comprising:
- at least one electrically conductive slip ring;
- at least one electrically conductive brush for supplying current to the at least one slip ring;
- and
- at least one electric actuator for oscillating the position of the at least one brush with respect to the at least one slip ring by providing a motion, wherein the motion is an azimuthal motion or an axial motion.
An assembly for transferring current, the assembly comprising:
- at least one electrically conductive slip ring;
- a plurality of brushes situated around a circumference of a support frame for supplying current to the at least one slip ring;
- and
- at least one electric actuator for oscillating the positions of the plurality of brushes with respect to the at least one slip ring.
An assembly for transferring current, the assembly comprising:
- at least one conductive slip ring;
- a plurality of electrically conductive brushes for supplying current to the at least one slip ring;
- and
- at least one electric actuator mechanically coupled to the support frame for oscillating the position of the brushes with respect to the at least one slip ring, wherein the at least one electric actuator is at least one induction motor or at least one voice coil actuator.
A method for transferring current comprising using at least one electric actuator for oscillating the position of at least one electrically conductive brush with respect to at least one electrically conductive slip ring while the at least one electrically conductive brush supplies current to the at least one slip ring.
