Abstract
A direct drive windshield wiper assembly including at least one brushless DC motor providing a drive torque through an output that is rotatable about the longitudinal axis of the motor and a windshield wiper that is driven by the motor about the longitudinal axis in a repeated wiping motion across the surface of a windshield. The motor including a planetary gear set having an output shaft, the gear set being coaxially disposed relative to the rotational output and the longitudinal axis of the motor and operatively interconnecting the drive torque and the windshield wiper, the gear set further operable to reduce the speed of the rotational output of the motor to the windshield wiper through the output shaft of the gear set.
