Abstract
PURPOSE:To obtain an electrically braking mechanism having high reliability with minimum additional components by controlling the comparing operation by a half- wave DC signal wherein the revolution speed of the motor and a set value is compared the time of braking. CONSTITUTION:When switches 15, 24 are shifted to contacts 15A, 24A sides respectively, half-wave DC current through diode D23 is smoothed at a capacitor (C) 19 and stabilized at a resistor (R)16 and a zener diode ZD17, and is applied to a comparison amplifier 6. The amplifier 6 receives a voltage generated at a rate generator 4 and a set voltage set by a setting potentiometer 5 and charges the C20 through the D18 with a current responsive to the difference therebetween. An oscillator circuit 21 is reset by a synchronizer circuit of R7. ZD8, D13 and D14 in every cycle of the power supply, and produces a gate pulse to the SCR3 while being controlled by the voltage at the C20. Accordingly, the SCR3 is controlled at its arc by the pulse from the circuit 31 to control the motor 1 through the diode bridge 2 to retain the set revolution speed by the potentiometer 5.
