Patent ID: 7105965

Claim:
An electric motor, comprising: a rotating cylindrical shaft ( 5 ); a frame ( 3 ) supported by the shaft ( 5 ) via roller bearings ( 10 , 11 ) and comprising, as a single continuous piece, an outer portion and an inner support member ( 3 a ); an attachment ( 6 ) connected to the frame and extending away from the shaft to a vehicle frame part, the attachment keeping the frame stationary; a stator ( 1 ) integral with the frame ( 3 ) and radially interior to the frame; a rotor ( 2 ) mounted interior to the stator and the outer portion of the frame; a projecting part of the rotor ( 2 c ) projecting, in both an axial direction and a radial direction, outside the stator ( 1 ), the rotor and the projecting part being a single continuous piece; a vehicle hub ( 4 ) fixed to the projecting part of the rotor and rotationally integral with the rotor, wherein, the support member ( 3 a ) is supported via the rolling bearings ( 10 , 11 ) on the shaft, the rotor is radially intermediate the inner, support member and the outer portion of the frame; and distance rings ( 17 ) located axially between the hub and a closest one of the rolling bearings ( 10 ), the distance rings clamping the hub.
