Abstract
A rotor mount assembly, located between a rotor shaft and a plurality of magnetic elements, resiliently damps vibrations induced from the plurality of magnetic elements. The rotor mount assembly includes a first resilient ring, a second resilient ring, and a laminated spacer. The laminated spacer includes laminates from a stator core center punch. Both resilient rings include an inner metal insert which, in one embodiment, comprises laminates.
Claims24
a method of constructing a rotor mount assembly to facilitate damping vibration of a rotor shaft, said method comprising the steps of:
- coupling a first resilient ring on the rotor shaft;
- coupling a second resilient ring on the rotor shaft;
- attaching a laminated spacer to the first resilient ring and the second resilient ring;
- and
- attaching a plurality of magnetic elements to the spacer.
A rotor mount assembly configured to damp vibrations at a rotor shaft of an electric motor having a plurality of magnetic elements, said assembly comprising:
- a first resilient ring;
- a second resilient ring;
- and
- a laminated spacer, said rotor mount assembly positioned between said rotor shaft and said plurality of magnetic elements.
A motor comprising:
- a motor housing comprising a pair of end shields and a shell, said end shields connected to said shell and at least one of said end shields comprising an opening, said shell comprising an opening;
- a stator assembly positioned within said motor housing and comprising a stator core and a stator bore extending therethrough, said stator core comprising a plurality of stator windings;
- and
- a rotor assembly positioned within said stator bore, said rotor assembly comprising a rotor mounting assembly, a plurality of magnetic elements attached to said rotor mounting assembly, and a rotor shaft extending through said rotor mounting assembly, said end shield opening, and said shell opening, said rotor mount assembly comprising a first resilient ring, a second resilient ring and a laminated spacer, said rotor mount assembly positioned between said rotor shaft and said plurality of magnetic elements and configured to damp vibrations induced from said plurality of magnetic elements.
