Abstract :
A motor control IC has been implemented for operating a small DC motor (≪5W) directly from the rectified mains using a Pulse Width Modulation (PWM) scheme. The integrated high voltage feedback loop ensures stabilization of the rotational speed at different mechanical loads in a supply range from 90-500 Vdc. The number of extermal components is reduced to those necessary for easy adjustment of relevant motor parameters such as speed and load compensation (3 resistors and 1 capacitor). This paper focuses on the design aspects of the conversion with high voltage circuits of the motor signas into signals at low voltage.
