Abstract:
A windshield wiper system (WWS) is provided and includes a brushless direct current (BLDC) motor with a motor output shaft gear, a gear train and an internally cut sector gear. The gear train includes a first gear, which has a first diameter and engages with the motor output shaft gear, and a second gear, which has a second diameter that is shorter than the first diameter and rotates with the first gear. The internally cut sector gear is coupled with an output shaft and formed to define an internal geared groove that engages with the second gear.
