STAR-DELTA STARTER EXPLAINED | CONTROL + POWER CIRCUIT STEP BY STEP

UNDERSTAND STAR-DELTA IN ONE SHOT! In this video, we explain the Star-Delta starter power circuit and control circuit in a simple, practical, and easy-to-follow way. You will learn how a 3-phase motor starts in STAR and changes to DELTA, and how the complete sequence works using: ✅ KM1 – Main Contactor ✅ KM2 – Star Contactor ✅ KM3 – Delta Contactor ✅ Timer ✅ Overload Relay ✅ START and STOP Push Buttons ✅ Holding Circuit ✅ Electrical Interlocking ✅ Motor terminals U1, V1, W1, U2, V2, W2 ✅ STAR starting and DELTA running sequence We also explain why KM1 remains energized, how the timer changes from STAR to DELTA, and how electrical interlocking prevents KM2 and KM3 from operating at the same time. This lesson is ideal for electrical students, electricians, technicians, apprentices, and anyone learning industrial motor control. 👍 If this video helps you, please LIKE, SUBSCRIBE, and leave your questions or suggestions in the comments below. ⚡ Budget Power Electrical Solutions Learn Electrical Systems Step by Step. #StarDelta #StarDeltaStarter #MotorControl #ControlCircuit #PowerCircuit #ElectricalEngineering #Electrician #ThreePhaseMotor #MotorStarter #ElectricalTraining
