Claims35
A cover for an electric motor including at least one lead wire, said cover comprising an inner face, an outer face, and at least one opening extending therebetween, said opening defined by a perimeter comprising at least one groove extending between said inner face and said outer face.
A can for an electric motor including at least one lead wire, said can comprising an inner face, an outer face, and at least one opening extending therebetween, said opening defined by a perimeter comprising at least one groove extending between said inner face and said outer face, said can configured to couple with an electric motor cover.
An electric motor comprising:
- a housing comprising a cover and a can, said cover fixedly coupled to said can, said housing comprising an inner face, an outer face, and at least one opening extending therebetween, said opening defined by a perimeter comprising at least one groove extending between said inner face and said outer face;
- a stator comprising at least one winding and a bore therethrough, said stator mounted in said housing;
- at least one lead wire electrically coupled with said at least one winding and configured for electrical connection with an electrical power source;
- a rotor shaft extending at least partially through said bore and said housing;
- and
- a rotor core mounted on said rotor shaft, said rotor core comprising at least one magnet.
A method for insulating an electric motor including a cover, a can, and at least one lead wire having insulation surrounding the at least one lead wire, said method comprising:
- inserting each respective lead wire between the cover and the can;
- and
- compressing the insulation between the cover and the can.
A cover for an electric motor including a can and at least one lead wire having insulation surrounding the at least one lead wire, said cover comprising at least one opening having a perimeter comprising at least one groove, said at least one groove configured to receive said at least one lead wire therein such that when said cover is fixedly attached to the can the insulation is compressed between said at least one groove and the can.
A can for an electric motor including a cover and at least one lead wire having insulation surrounding the at least one lead wire, said can comprising at least one opening having a perimeter comprising at least one groove, said at least one groove configured to receive said at least one lead wire therein such that when said can is fixedly attached to the cover the insulation is compressed between said at least one groove and the cover.
