Zusammenfassung:	In a preferred embodiment of the present invention, a safety power window system detects a ripple current in an output current signal of a motor, calculates the number of revolutions of the motor using an instantaneous variation amount of the detected ripple current signal, and controls drive of the motor based on the calculated number of revolutions. 본 발명의 바람직한 일 실시예에서, 세이프티 파워윈도우 시스템은 모터의 출력 전류 신호 에서 리플 전류를 검출하고, 검출된 리플 전류 신호의 순간 변화량값을 이용하여 모터의 회전수를 계산하며, 계산된 회전수를 기초로 모터의 구동을 제어하는 특징이 있다.
