Abstract:
1. An electric induction motor assembly comprising: a rotor assembly rotatable about an axis; a stator assembly spaced radially from the rotor assembly; said stator assembly comprising a plurality of axially stacked stator laminations, each of said stator laminations presenting a punched-to-size radially inner periphery, said rotor assembly including an exposed bar rotor assembly, said exposed bar rotor assembly comprising a plurality of axially stacked rotor laminations, each of said rotor laminations presenting a punched-to-size radially outer periphery, each of said stator laminations and rotor laminations presenting an axial thickness of less than 0.024 inches, said stator assembly and said rotor assembly cooperatively defining an air gap extending radially between the radially inner periphery of the stator assembly and the radially outer periphery of the rotor assembly, said air gap presenting a radial dimension of less than 0.012 inches.
