Abstract: Disclosed is an aircraft windshield wiper system, having: a wiper arm (110); a reversible motor (130) that drives the wiper arm, the motor including: a stator (155a); a rotor (155b) configured to rotate relative to the stator; a forward shaft segment (140b) that is driven by the rotor and being rotationally connected to the wiper arm; an aft shaft segment that is driven by the rotor, the aft shaft segment including a forward end and an aft end; a ball nut that translates along the aft shaft segment from rotation of the aft shaft segment (140c); a forward stop at a forward end of the aft shaft segment, configured to stop forward translational motion of the ball nut along the aft shaft segment; and an aft stop at an aft end of the aft shaft segment, configured to stop aft translational motion of the ball nut along the aft shaft segment.

Abstract: A windshield wiper system (WWS) (10) includes a brushless direct current (BLDC) motor (20) with a motor output shaft gear (22), a gear train (30) and an internally cut sector gear (40). The gear train (30) includes a first gear (31), which has a first diameter (D1) and engages with the motor output shaft gear (22), and a second gear (32), which has a second diameter (D2) that is shorter than the first diameter (D1) and rotates with the first gear (31). The internally cut sector gear (40) is coupled with an output shaft (50) and formed to define an internal geared groove (41) that engages with the second gear (32).
