Have you ever seen a three-phase motor change direction when the phases are swapped? It can be confusing, but it's actually quite simple when you understand how induction motors work. In this video, we'll look at the principle of rotating magnetic fields and explore why 3-phase motors reverse rotation when the phases are swapped. ================================================================ 00:00 Why do three-phase motors change direction by swapping phases? 00:51 How does a three-phase motor construction 02:06 Understanding the three-phase waveform and current flow 03:20 Magnetic field direction 05:05 The rotating magnetic field 05:41 Squirrel cage 06:27 The answer! ================================================================ Checkout the Scame Phase Rotation socket - and easy way to quickly swap phases 📺 👉   • The Secret Device Hidden Inside This Indus...   ================================ 🔦 More electrical Q&A videos from eFIXX 👉 https://www.efixx.co.uk/electricians-... ================================ 🆕 FREE CPD Learn about new applications, regulations and best practices with our FREE CPD modules. - New modules are released monthly, covering everything from surge protection to lighting. 👉http://hub.efixx.co.uk/CPD​ ================================ 📍SUBSCRIBE TO THE CHANNEL eFIXX helps electricians, electrical contractors, building services engineers, and electrical apprentices.
