In the field of speed control for both D.C. and Induction motors the voltage control method using thyristors has been extensively used with its advantage in improving the efficiency and performance of variable speed driving equipment. To be added to this will be a frequency control method for brushless A. C. motors which employs thyristors and features freedom from maintenance.
The article describes the present status and future prospects of motor speed control systems.
