![]() ![]() The Q1, Q2, Q3 contactors must be chosen according with rated power of your motor. When overload occur circuit breaker opens Q1 so the motor is stopped. In a similar manner things take place if we want to change the direction of rotation, thereby pressing Reverse button contactor Q3 is connected so the motor is rotating counterclockwise, this is possible only by activating previously the Stop button. By pressing Forward push button the Q2 coil contactor is energized the motor will be connected for clockwise run and maintains itself after the button Reverse by means of auxiliary switch Q2, the Stop button and the auxiliary contact of Q3, which serves as interlock, thus avoiding simultaneous connection of Q2 and Q3 contactors. Operating mode: Same as for direct on line starting instead of fuses and thermal relay you can use a motor circuit breaker with thermal and magnetic trips, a simple but at least as effective component. According to this connection diagram, you will connect with the component in this way.Motor protection with MCB with thermal and magnetic trips I have shown the connection diagram above. You can use magnetic contactors instead of relays to drive the AC motor forward and reverse, or you can use relays of higher amperes. ![]() You can run the AC motor forward and reverse through this simple circuit. ![]() You can take the power supply and take it according to the voltage of the motor you want to run forward and reverse. Here I have shown how to operate a 5v motor using a 5v relay. Now we will look at the circuit diagram for moving the motor forward and reverse. Let’s find out what components will be needed to create a simple motor forward and reverse circuit. Through this post, I will show you how to easily create a circuit that can move a motor forward and reverse. , DC motor forward and reverse controller, speed control drive board, serial port control, upper computer process. Again AC motor may require this circuit to run forward and reverse. This circuit is required for DC motor to run forward and reverse. This circuit is required to drive a motor forward and reverse. Motor forward reverse control circuit can be made very easily. ![]()
