Patent ID: 7259487

Claim:
An electric machine comprising: a stator assembly having a stator core and a coil supported by the stator core, the stator core defining a first bore; a rotor assembly having a shaft, a rotor supported by the shaft for rotation with the shaft relative to the stator core, and first and second bearings secured to the shaft on opposite sides of the rotor; a first bearing housing that receives the first bearing and defines a second bore which aligns with the first bore; a second bearing housing that receives the second bearing and defines a third bore which aligns with the first and second bores; a first fastener received in the second, first, and third bores to secure the first and second bearing housings to the stator assembly with the first and second bearings received at least partially within the first and second bearing housings, respectively; a circuit board; a second fastener that secures the circuit board to the second bearing housing, the second fastener being spaced from the first fastener; and wherein the stator core includes a C-frame portion that is formed of non-grain-oriented electric steel that defines a rotor opening and an I-bar portion that is formed of grain-oriented electric steel.
