Abstract
PURPOSE: To perform the speed control of an indution machine by an inexpensive means, by sensing the frequency of the terminal voltage of the induction motor and inputting the result to an signal-speed-control amplifier.
CONSTITUTION: When a load is applied to an induction machine 6, the number of rotation of the induction machine 6 is decreased, and the frequency of the terminal voltage of the induction machine 6 is also decreased. The frequency is sensed by a frequency sensor 19 through a transformer 8, and the output signal of the sensor 19 and the signal from speed setting adjuster 18 are compared and amplified in a speed control amplifier 17. A triggering signal is applied to the thyristors in the first power converter 2 through a current control amplifier 15, a phase control circuit 14, and a triggering circuit 13 so that the frequency of the terminal voltage of the induction machine 6 becomes a specified value.
