FORWARD AND REVERSE MOTOR STARTER WITH TIMER DIAGRAM PDFPdf last forward stop reverse 3 phase wiring diagram. Now in the below diagrams three phase motor will rotate in two directions viz forward and reverse. forward reverse 3 phase ac motor control star delta wiring diagram. Three phase motor connection stardelta y d reverse and forward with timer power control diagram as we have already shared the starting method of three phase motor by star delta starter with timer circuit power and control circuits.īut we have controlled the direction of rotation of.įigure 2 forwardreverse motor wiring diagram. So this time i want share my simple star delta circuit diagram completed with power and control line circuiti hope it can be as basic reference for. Now in the below diagrams three phase motor will rotate in two directions viz fo. Star delta forward reverse wiring diagram pdf. The Q1, Q2, Q3 contactors must be chosen according with rated power of your motor.In this tutorial we will show the star delta y d 3 phase induction ac motor starting method by automatic star delta starter with timer with schematic power control and wiring diagram as well as how star delta starter works and their applications with advantages and disadvantages. To reverse the motor, you have to connect the motor and supply phase in such a condition. When overload occur circuit breaker opens Q1 so the motor is stopped. Forward & Reverse Direction of Induction Motor wpadcamp1 Example: You have a motor (motor terminal U, V, W) which is connected with the phase sequence (Supply phase R, Y, B) of R-U, Y-V, B-W in a forward direction. 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.
