This video explains how to identify all six leads (U1-U2, V1-V2, W1-W2) of a three-phase induction motor using only a digital multimeter (VOM) and a 9-volt battery — step by step with clear technical visuals. When the original wire labels are faded or missing, this method allows you to correctly find each coil pair, determine the start and end of every winding, and connect the motor safely in Star (Y) or Delta (Δ) configuration. 🔍 What You’ll Learn How to use a multimeter to locate three coil pairs through resistance testing. How to use a 9-V battery to determine coil polarity (start & end). The difference between Star (Y) and Delta (Δ) wiring. Common measurement mistakes and how to avoid them. Key safety tips when testing and labeling industrial motor leads. 🧰 Tools Required Digital multimeter (VOM) 9-V battery Marker or colored wire labels Notebook and pen 👩‍🔧 Who This Is For Technicians, students, and engineers in mechatronics, electrical maintenance, and industrial automation who want practical, hands-on motor testing knowledge. 🙌 Call to Action If this video helps you, Like, Subscribe, and Share to support Hexabot, and comment which technical topic you’d like next! 🔖 Hashtags #hexabot #motor #3phasemotor #mechatronics #automation #maintenance #multimeter #electricalengineering #industrialtraining
