Abstract

PURPOSE: To realize an extremely-simple system which eliminates the need to pay attention to the amplification degree, phase compensation, mechanical rigidity, back crash, etc. of elements constituting the system, by using an ON/OFF position control system.
CONSTITUTION: Output signal 11 from synchro-control transformer 9 is supplied to ON/OFF control circuit 22 and synchronous demodulating circuit 13 converts the AC voltage into a DC voltage. Output signal 23 of synchronous demodulating circuit 13 is supplied to over-drive circuit 24, output signal 25 of which is supplied to relay circuit 28 via relay driving circuit 26 to determine the rotatory direction of induction motor 29. Output signal 23, on the other hand, is supplied to absolute-value circuit 30, whose output signal 31 is applied to comparing circuit 32 to detect whether it is above or below a certain level, and output signal 33 of the comparing circuit is supplied to relay circuit 28 via relay driving circuit 34 to turn ON-OFF the main circuit of induction motor 29.
