Claims8
An electric motor structure comprising:
- an electric motor having a housing and an endcap coupled to an end of the housing, the endcap including a bearing pocket constructed and arranged to cover a distal end of a bearing structure, and
- a heat shield coupled directly to the motor so as to surround and cover the bearing pocket, the heat shield being spaced from the bearing pocket and being directly adjacent to a portion of the bearing pocket covering the distal end of the bearing structure,
- wherein the housing includes a plurality of tabs and the endcap includes slots with each slot receiving an associated tab.
An electric motor structure comprising:
- an electric motor having a housing and an endcap coupled to an end of the housing, the endcap including a bearing pocket constructed and arranged to cover a distal end of a bearing structure, and
- a heat shield having a planar peripheral portion and a bowl-shaped portion extending from the planar peripheral portion, at least a portion of the planar peripheral portion being coupled directly to the motor so that the heat shield surrounds and covers the bearing pocket, with the bowl-shaped portion being spaced from the bearing pocket and being directly adjacent to a portion of the bearing pocket covering the distal end of the bearing structure,
- wherein the housing includes a plurality of tabs and the endcap includes slots with each slot receiving an associated tab.
