SEO Keywords Quick exam-smart one-liners — Transformer (No-load, Turn ratio, Tricks) 1) No-load current (I0) is small and mostly magnetizing current — think of it as "keeping the core awake"; it flows when secondary is open. 2) Turn ratio (a) = N1/N2. Remember: a>1 = step-down, a<1 = step-up for voltages when using Nprimary:Nsecondary. 3) Open-circuit test measures core loss and magnetizing current — apply rated voltage to primary and leave secondary open (very common AE/JE question). 4) ...

3 Phase AC MOTOR Table of Contents Introduction — What is a 3-phase AC motor? Key concepts and Why it matters in AE/JE exams Important one-liners (30+) Related posts you may like Join our channels & Donate Ads & Keywords Important One-liner Tricks & Short Notes (most asked in AE/JE) 1 Synchronous speed (Ns) in RPM = (120 × f) / P — quick trick: double frequency -> double speed, halve poles -> double speed. 2 Slip (s) = (Ns − N) / Ns — for induction motors slip is small (typically 1–6%) at rated load; memorize typical ranges for exam questions. 3 Induced EMF in an AC motor is proportional to flux × speed; reduce speed → reduce EMF (used in V/f control explanation). 4 Full-load torque ∝ (Power) / (speed) — for same power, lower speed yields higher torque; useful for gearbox selection examples. 5 Locked-rotor current (sta...

AC motor definition An AC motor converts alternating current electrical power into mechanical torque using rotating magnetic fields — remember: "Alternating creates rotation". 2. Synchronous speed (Ns) Ns (rpm) = 120 × f / P. Quick trick: double frequency or halve poles doubles speed — used often in speed selection problems. ...
