The housing includes first and second housing components directly engaging one another along a housing interface. The housing at least in part defines a sealed chamber. The shaft is at least in part received in the chamber. The bearing rotatably supports the shaft. The bearing plate is enclosed within the housing. The bearing plate supports the bearing within the housing. The seal is disposed along the housing interface. The bearing plate is spaced inwardly from the housing interface and the seal. ## Claims ### Claim 1 A motor comprising: a housing comprising a first housing component and a second housing component directly engaging each other along a housing interface, said housing defining a sealed chamber; a shaft at least in part received in said sealed chamber; a bearing rotatably supporting said shaft; a bearing plate enclosed within said housing, said bearing plate supporting said bearing within said housing; and a seal disposed along the housing interface; said bearing plate being spaced inwardly from the housing interface and said seal, said bearing plate being coupled to said second housing component, said first housing component including a lip circumscribing said bearing plate, said lip defining a planar first engagement surface, said second housing component including a planar second engagement surface abutting said first engagement surface along the housing interface, said bearing plate defining a planar mounting surface abutting said second engagement surface along a bearing plate interface. ### Claim 2 (depends on 1) The motor in accordance with claim 1, said lip engaging said second housing component along the housing interface. ### Claim 3 (depends on 2) The motor in accordance with claim 2, said lip including a radially innermost perimetrical surface, said bearing plate including a radially outermost perimetrical surface spaced from said radially innermost perimetrical surface of said lip such that a perimetrical gap is formed therebetween. ### Claim 4 (depends on 1) The motor in accordance with claim 1, said second housing component including a positioning peg, said bearing plate including a positioning hole corresponding to said positioning peg, said bearing plate being coupled to said second housing component such that said positioning peg is received in said positioning hole. ### Claim 5 (depends on 1) The motor in accordance with claim 1, said second housing component including a groove defined along the housing interface opposite said lip, said groove at least partially receiving said seal therein. ### Claim 6 (depends on 5) The motor in accordance with claim 5, said bearing plate spaced inwardly from said lip, defining a gap therebetween. ### Claim 7 (depends on 5) The motor in accordance with claim 5, said seal and said groove being perimetrically continuous. ### Claim 8 A motor housing comprising: a first housing component; a second housing component coupled to said first housing component along a housing interface, said first and second housing components defining a sealed chamber; a seal disposed along said housing interface; and a bearing plate coupled to at least one of said first and second housing components, said bearing plate being configured to support a bearing within the sealed chamber, said bearing plate being spaced inwardly from the housing interface and said seal, said first housing component including a lip circumscribing said bearing plate, said second housing component including a groove defined along the housing interface opposite said lip, said groove at least partially receiving said seal therein, said bearing plate spaced inwardly from said lip so as to define a gap therebetween. ### Claim 9 (depends on 8) The motor housing in accordance with claim 8, said bearing plate being coupled to said second housing component. ### Claim 10 (depends on 9) The motor housing in accordance with claim 9, said lip engaging said second housing component along the housing interface. ### Claim 11 (depends on 10) The motor housing in accordance with claim 10, said lip including a radially innermost perimetrical surface, said bearing plate including a radially outermost perimetrical surface spaced from said radially innermost perimetrical surface of said lip such that a perimetrical gap is formed therebetween. ### Claim 12 (depends on 9) The motor in accordance with claim 9, said lip defining a planar first engagement surface, said second housing component including a planar second engagement surface abutting said first engagement surface along the housing interface. ### Claim 13 (depends on 12) The motor housing in accordance with claim 12, said bearing plate defining a planar mounting surface abutting said second engagement surface along a bearing plate interface. ### Claim 14 (depends on 8) The motor housing in accordance with claim 8, said second housing component including a positioning peg, said bearing plate including a positioning hole corresponding to said positioning peg, said bearing plate being coupled to said second housing component such that said positioning peg is received in said positioning hole. ### Claim 15 (depends on 8) The motor housing in accordance with claim 8, said seal and said groove being perimetrically continuous. ### Claim 16 A motor housing comprising: a first housing component; a second housing component coupled to said first housing component along a housing interface, said first and second housing components defining a sealed chamber; a seal disposed along said housing interface; and a bearing plate coupled to at least one of said first and second housing components, said bearing plate being configured to support a bearing within the sealed chamber, said bearing plate being spaced inwardly from the housing interface and said seal, said bearing plate being coupled to said second housing component, said first housing component including a lip circumscribing said bearing plate, said lip defining a planar first engagement surface, said second housing component including a planar second engagement surface abutting said first engagement surface along the housing interface, said bearing plate defining a planar mounting surface abutting said second engagement surface along a bearing plate interface. ### Claim 17 (depends on 16) The motor housing in accordance with claim 16, said second housing component including a positioning peg, said bearing plate including a positioning hole corresponding to said positioning peg, said bearing plate being coupled to said second housing component such that said positioning peg is received in said positioning hole. ### Claim 18 (depends on 16) The motor housing in accordance with claim 16, said lip engaging said second housing component along the housing interface. ### Claim 19 (depends on 18) The motor housing in accordance with claim 18, said lip including a radially innermost perimetrical surface, said bearing plate including a radially outermost perimetrical surface spaced from said radially innermost perimetrical surface of said lip such that a perimetrical gap is formed therebetween. ### Claim 20 (depends on 16) The motor housing in accordance with claim 16, said second housing component including a groove, said groove at least partially receiving said seal therein, said seal and said groove being perimetrically continuous.
