Document Type and Number:
Japanese Patent JP2013524767
Kind Code:
A
Abstract:
In one embodiment, a rotor for an induction motor comprises a punching assembly, a plurality of conductive bars, and an end-ring. The plurality of conductive bars may be substantially parallel to an axis of the rotor and connected to the punching assembly at a periphery of the punching assembly. Each conductive bar includes an end connected to the end-ring. The end-ring comprises a punching side having a surface facing the punching assembly and a housing side having a surface opposite the punching surface. The end-ring may be thicker on the punching side than the housing side. In this manner, the peak end ring stresses may be reduced at higher speeds and the mean time between failures of the rotor may be increased. Alternatively, the threshold speed may be increased and the top-speed of the off-highway vehicle may be increased for a given expected mean time between failures of the rotor.
