In any motor, when we do Blocked Rotor Test, what actually happens? Is it that the full power is consumed in core loss? Is the current that flows through the armature is rated current? In fact what sort of physical phenomena occurs when the rotor is blocked ?
E(a)=kΦω .....E(a) being the induced voltage
right? so when the rotor is blocked, ω=0 i.e. E(a)=0......so the current flow will be maximum in the armature. Is this maximum current called the rated current in a motor ? then the induced torque will be maximum as
ζ (ind)=k*Φ*I(a)
see, I cant make anything out of it?
