Hi
im using a microcontroller for On and Off AC (230V) motor (its a fuel pump actually ) , the AC motor control through a AC contactor ( contactor connect through 5v relay and 5v relay interface to microcontroller through optocoupler for additional protection) , but when the motor ON and OFF...
Hi everyone,
Does anyone know how to do this and paste a link or name of legit, academic, source ? I only know the back-EMF constant from my motor but I need the rotor flux. Please any help would be greatly appreciated.
If a 100 KVA star-connected 400 V three-phase, 60 Hz synchronous generator with armature resistance 0.35Ω/phase and 3.5Ω reactance and leakage resistance given is 1Ω/phase. Calculate at rated load and unity power factor at
i) No load e.m.f
ii) Internal e.m.f.
iii) percentage of regulation at...
