Abstract
PURPOSE: To drive this motor in the desired number of revolution even to the variation of line voltage, by obtaining pulse signals proportional to the number of revolution of the motor, and by controlling the application or interruption of power to the motor on the basis of the length of the pulse period.
CONSTITUTION: When the number of revolution of a direct current motor M is speed controlled so that the number of revolution each become to fixed speed 4500, 2000, 1000, 200 r p m, an AND circuit 22 emits output signals SP2 that are each frequency divided into 1/5, 1/2, 1, 1 to speed pulse signals from a pulse generator 16 if a rotary switch 14 is set to a termianl corresponding to the desired set number of revolution. Meanwhile, a subsraction counter 24 also operates so that the value of 335, 300, 1500 each be subtracted on the basis of clock pulses in response to the functioning of the AND circuit. Thus, whether or not the subtraction counter 24 finishes the subtraction of value each preset until the counter 24 receives the next signals SP2 is discriminated by the output signals of an OR circuit 26, and the speed of the motor M is controlled by the conditions of the output signals.
