Title:
ROTOR AND GENERATOR FOR REDUCING HARMONICS
Document Type and Number:
WIPO Patent Application WO/2014/018915
Kind Code:
A3
Abstract:
A rotor for a generator comprises a stack of laminate plates and conductive end caps on either side thereof. The laminate plates and the end caps have holes near a periphery thereof, and conductive rods are positioned in the holes, and secured to the end caps. The stack, the end caps and the rods are then skewed by a desired angle with respect to a centerline of the rotor. The resulting rotor core may then be mounted to a rotor shaft, and wound, with the windings also being skewed due to skewing of the core. The end caps and rods form a damper cage that aids in reducing harmonics.
