So relay pulls in as Graph of time function in Figure 3. Restarting with increasing AC voltage about 215 volts (as setting). If the main have ripple voltage,this will not works because the motor may be damaged. This is a special feature, it will cut off the load at once, when the AC main is under voltage into setting value. We will also connect the resistor-R5 across pin 6 and pin 3 of IC1, to set circuit in Schmitt trigger form. It may cause IC1, the relay-RY1 works with the error. Pin 3 will be connected to capacitor C3 to reduce the fluctuating voltage to smooth. So this will apply a relay pulls in and connects AC electrical current to the motor or AC load.įigure 2 The schematic of Motor burn out and under-voltage protection We will set this voltage slightly lower than the reference voltage. It will compare voltage between the reference voltage of ZD1- 3.6 volts the Zener diode, and input voltage from pin 3 of IC1 this voltage is divided by resistor-R4 and VR1. There is an op-amp-IC1 as an input voltage comparator. Ideally, block diagram in Figure 1.įigure 1 the block diagram The working of the motor protection circuitįigure 2 is a schematic of this project. Until the voltage is restored to its original condition. And AC-line fall down lower than 10% of normal voltage the relay will cut off the load at once. Can be set to cut no-off in the voltage during the 168-227V.Īs AC main in normal level, the relay will be connect to apply AC line to motor. Relay will not work and the LED is a warning. The principle is simple, it will check for voltage at all times. It will protect the AC motor burn out. Because of under voltage input. Should be careful polarity of the diodes, Zener diodes, electrolytic capacitors types Induction Motor Protection Circuit and working All equipment will be soldered onto the PCB purpose. ZD2: 6.8V 0.5W Zener Diode C1: 470♟ 25V Electrolytic Capacitors C2,C3: 0.1♟ 63V Polyester Capacitor LED: as you like.IC2: LM7812_12V 1A DC voltage regulator.IC1: LM324_ Quad/ 1MHz/ Operational Amplifiers.LED1 display when power or low power over a specified. The two components can be specified by VR1, VR2. The IC2/2 serves to detect the lower voltage. Thus cutting off power from the load instantly. Pressure acts edge IC2/1 High Voltage Detector, High Voltage ICs, if this current work to the Q1 and relay function, it works with. Or input pin of IC1, a loan IC Rex bit computing to 12-volt power supply is fixed to the IC2. Then, through the C1 and C2 to the power filter smoothing. To convert the voltage, alternating current to direct current. It serves to reduce the pressure remaining 12 volts, through a D1-D4 connected to Direct rectifier bridge circuit.
