Abstract
A windshield wiper assembly including at least one motor having an output shaft and a windshield wiper operatively connected to the output shaft. The motor includes a stator adapted to provide an electromagnetic flux and a rotor assembly supported for rotation about the stator. The rotor assembly includes a back iron that defines an inner circumference and a plurality of magnets disposed in spaced parallel relationship relative to one another about the inner circumference of the back iron and in radially spaced relationship about the stator. The rotor assembly is operatively connected to the output shaft and responsive to electromagnetic flux generated by the stator so as to provide a rotational force to the output shaft to drive the windshield wiper in repeated wiping motion across the windshield.
