Abstract:
A brushless DC motor includes a stator formed of a lamstack including a plurality of stacked laminations. The stator includes a plurality of radially extending core members and a circumferential wall. An intersection of each of the plurality of radially extending core members with the circumferential wall defines a flux null location, and a portion of the lamstack defines a first opening located at one of the flux null locations. The brushless DC motor includes a printed circuit board including a second opening and a grounding member including a first section received in the first opening of the stator and a second section received in the second opening of the printed circuit board to create a grounding path.
