Patent ID: 7171718

Claim:
A windshield wiper assembly comprising: at least one motor having an output shaft and a windshield wiper operatively connected to said output shaft such that said windshield wiper may be driven in repeated wiping motion across the surface of the windshield; said motor including a stator adapted to provide an electromagnetic flux and a rotor assembly supported for rotation about said stator, said rotor assembly including a back iron defining an inner circumference, a rotor cap operatively coupled to said back iron and an annular magnet mounted to said inner circumference of said back iron so as to be disposed in radially spaced annular relationship about said stator, said motor further including a planetary gear set including a sun gear operatively supported by said rotor cap for rotation with said rotor assembly, said rotor assembly operatively connected to said output shaft through said rotor cap and said sun gear and responsive to the electromagnetic flux generated by said stator so as to provide a rotational force to said output shaft to drive said windshield wiper in repeated wiping motion across the windshield.
