Now in the below diagrams three phase motor will rotate in two directions viz forward and reverse. A star delta starter is the most commonly used method for the starting of a 3 phase induction motorin star delta starting an induction motor is connected in through a star connection throughout the starting period.

Delta motor connection diagram. For star delta staterthe motor connection must have 6 cables from control panel and 6 terminals at induction motor u1u2v1v2w1w3to wiring the motor connection for star delta starterthe important thing that we must fully understand is about the basic of star delta magic triangle. Star delta starter wiring diagram this post is about the main wiring connection of three phase motor with star delta starter and control wiring diagram of star delta starter. Wye start delta run motor wiring diagram ms3 mega wiring diagram on hyosung wiring diagram wire center u2022 rh daniablub co wye start delta run wiring diagram air pressor delta and wye. For three phase motor we use the direct online starter but mostly for small three phase motor. Assortment of wye start delta run motor wiring diagram. The phasor diagram is shown below.
Hence in delta connection line voltage is equal to phase voltage. Then once the motor reaches the required speed the motor is connected in through a delta connection. Three phase motor connection stardelta y δ 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. As in the balanced system the three phase current i 12 i 23 and i 31 are equal in magnitude but are displaced from one another by 120 electrical. Relation between phase current and line current in delta connection. But high load 3 phase motor we use the star delta starter for motor.
