Abstract
Embodiments disclosed herein describe methods for an improved electrical connector system.
Claims20
A permanent magnet motor system, comprising:
- a shaft with a proximal end and a distal end, wherein permanent magnets are positioned on an outer circumference of the shaft;
- a stator positioned around the shaft;
- bearings positioned around a distal end of the shaft, the bearings positioned between the stator and a distalmost end of the shaft;
- a grounding ring positioned adjacent to the bearings;
- a retention nut positioned adjacent to the grounding ring, wherein the grounding ring is configured to provide a preferred current flow path associated with a voltage potential between the stator and the shaft.

A method associated with permanent magnet motor system, comprising:
- positioning permanent magnets on an outer circumference of the shaft between a proximal end of the shaft and a distal end of the shaft;
- positioning a stator around the shaft;
- positioning bearings around a distal end of the shaft, the bearings being positioned between the stator and a distalmost end of the shaft;
- positioning a grounding ring adjacent to the bearings;
- positioning a retention nut adjacent to the grounding ring;
- providing a preferred current flow path associated with a voltage potential between the stator and the shaft to ground through the grounding ring.
