Power circuit and control circuit pdf
WebThis type of AC motor speed control gives a fully variable and linear control because the voltage can be adjusted from zero to the full applied voltage as shown. Phase Control This basic phase triggering circuit uses the triac in series … WebAs the circuit exists right now, the motor will run either forward or backward once the corresponding pushbutton switch is pressed, and will continue to run as long as there is power. To stop either circuit (forward or backward), we require some means for the operator to interrupt power to the motor contactors. We’ll call this new switch, Stop:
