摘　　要：由于直流电动机具有优良的调速特性,调速平滑、方便,所以,在工业及人们生活中都在广泛地使用直流伺服系统。本文利用最常见的用于电源的PWM电压调节芯片TL494,设计成直流电机调速控制电路。As a result of DC Motor having nicer speed-varying characteristic, the speed- varying of DC motor is smoothness and convenience, therefore the DC servo control system is used abroad in diver- sified occasion. This paper makes use of ordinary power supply chip TL494, which having characteristic of PWM output, DC motor speed-varying control circuit has been designed.

关 键 词：直流调速 TL494 控制电路
