Abstract
An electric motor includes a rotor cup housing having an annular flange extending circumferentially from a sidewall. The motor further includes a stator including a stator core having a winding thereon and a rotor positioned at least partially around the stator. A rotor shaft is positioned at least partially within the stator.
Claims16
A method for fabricating a rotor cup, said method comprising the step of stamping the rotor cup frame and forming an annular flange surrounding an opening of the rotor cup.
A rotor cup assembly for an electric motor, said rotor cup assembly comprising a housing comprising a top, a bottom, a sidewall extending circumferentially from said top and having a first diameter, said sidewall and said top defining a cavity, and an annular flange extending circumferentially from said sidewall and having a first diameter, a second diameter, and a first thickness, said first diameter less than said second diameter.
An electric motor comprising a stator including a stator core having a winding thereon, a rotor positioned at least partially around said stator, a rotor shaft positioned at least partially within said rotor, and a rotor cup, said rotor shaft extending through said rotor cup, said rotor cup comprising:
- a housing comprising a top, a bottom, a sidewall, and an annular flange, said sidewall extending circumferentially from said top and having a first diameter, said annular flange extending circumferentially from said sidewall and having a first diameter, a second diameter, and a first thickness, said first diameter less than said second diameter.
