this is a motor driver unut circuit.
This unit will handle all high voltage (220/230V AC 50 Hz) and drive the motor.
• High voltage circuitry to trig a 24W 230VAC induction motor into drive mode.
There must be isolation between the low voltage circuitry and high voltage circuitry of the
induction motor.
• The speed of the motor should be determined by the Speed Reference unit
this is the design of the circuit:
I want to know in detail how this circuit functions in order to meet the above requirements. please assist soon.
the second photo attached is what I have interpreted the circuit as. is my interpretation correct and if there is any additional information please let me know. thank you
The above circuit diagram makes use of a zero cross detector circuit which produces an output to the 555 timer. This circuit comprises of operational amplifiers, resistors, and capacitors. It works by producing an output pulse by finding a point supplied by the AC signal which has a zero voltage and can be used as a comparator. The timer then generates an output PWM wave which is used as the input to the MOC8101_BASSO. The timer is operating in the monostable function. The PWM wave allows for the speed control of the motor. This is achieved by controlling the circuit's current by varying the time of each flow at every component. A phase triggering circuit uses the triac to control and apply a chopped AC waveform to the induction motor. The triac is a bi-directional device. The resistor in series controls the voltage supply to the motor. The voltage is triggering for each cycle once the capacitor charges and discharges, thus allowing the gate of the triac activate. The process discontinues when the half-cycle ends only to repeat itself. This allows for the positive and negative pulses in a sinusoidal waveform. It changes the control of AC supply.
