What is Universal Motor What are the Best Speed

Continuous speed control of a universal motor running on DC is very easily accomplished using a thyristor circuit. A thyristor supplies the motor during the positive mains half cycle. Both the thyristor and its control are connected in such a way that the motor back-EMF compensates the motor load variations to adjust the speed.
