A wiper motor system has a motor controller (32A) for controlling an output shaft (14A, 14B) of a motor (12A, 12B) based on information received from a rotational position sensor (36A, 36B) and a mechanical resistance sensor (38A, 38B). The motor controller (32A) is capable of changing the instantaneous RPM or output torque of the motor (12A, 12B) based on the rotational position of the wiper arm (16A, 16B) or the amount of mechanical resistance coupled to the output shaft (14A, 14B) of the motor (12A, 12B). A wiper system having two non-mechanically linked motors (12A, 12B) includes a motor controller (32A) to prevent the wiper arms (16A, 16B) coupled to each motor (12A, 12B) from colliding. A linkage coupled to a motor (12A, 12B) converts the rotation of the output shaft (14A, 14B) of the motor (12A, 12B) to a reciprocating motion of a wiper arm (16A, 16B). |
