Speed control for 3-phase AC motors

Speed control for 3-phase AC motors
Three-phase motors, particularly asynchronous types, are very reliable and consequently popular prime movers. A drawback of these engines is, however, their fixed speed of rotation which depends on the frequency of the applied voltage. This article describes means of varying that frequency and thus controlling the speed of the motor over a wide range.
