Abstract: The opening and closing of elevator is a velocity conversion process which needs velocity modulation on driving motor of elevator door system. This paper presents a frequency conversion velocity modulation control system based on MCU(87C196MC) with high performance. Specialized integrated circuit IR2130 for driving MOSFET is adopted as power driver. Analyse the method which controls the running of elevator door-motor based
PWM technique. Combine AC frequency converter and drive controller of door-motor system as one unit by adopting MCU and specialized integrated circuit. Get an elevator control system which is reliable, flexible, low cost and small in size.
