Blocked rotor test on three phase induction motor
During blocked-rotor test on a 3-ø IM, the power input to 3-phase IM has to supply
The diameter of the circle diagram for a 3-ø IM is given by (V1 = stator phase voltage)
The approximate value of efficiency of a 3-phase IM running at a slip 's' is given by
To improve the power factor of a 3-phase IM, the capacitor bank should be connected in delta to make
A 3-phase induction machine runs at super synchronous speed. For self-excitation, the machine
