The phase difference of coils between a low and an earth currently used when automatically stopping a motor is 180 degrees, and coils in a section which does not come in contact with brushes divide a force in a clockwise and a counterclockwise direction to stop the motor. The present invention uses brushes (high-earth, low-high) with a phase difference different from 180 degrees in a closed loop to stop a motor. An N value of a counter electromotive force can be lowered if a high brush in a relatively small angle in comparison to a brush stopping method of a phase difference of 180 degrees which is stopped by a large force is used for automatic stopping. A wiper motor can be relatively smoothly stopped in comparison to a conventional method where the wiper motor is abruptly stopped.

    현재 자동정지 시 사용되는 로우(Low)와 어스(earth) 사이에 코일(coil) 위상차는 180도 이며 브러시와 접촉되지 않는 구간의 코일들은 시계방향 반시계방향 두가지로 힘이 나뉘어 모터를 정지시킨다. 본 발명은 180도 위상차가 아닌 다른 브러시들(High - Earth, Low - High)을 폐루프로 사용하여 모터를 정지시킨다. 큰 힘으로 정지되는 180도 위상차의 브러 정지방법과 달리 상대적으로 작은 각도에 있는 하이 브러시를 자동정지로 사용할 경우 역기전력의 N 값을 낮출 수 있다. 이는 갑작스럽게 정지되는 기존 방법과 달리 상대적으로 부드럽게 와이퍼 모터를 정지시킬 수 있다.
