Blocked Rotor Test

As discussed in the previous post Blocked Rotor Test of Induction Motor, the rotor is prevented from rotating and then a small voltage is applied to the stator sufficient to pass the rated current through the stator winding and then leakage impedance of Induction Motor is calculated. The question may arise that why don’t we … Read more

As the name of the test specifies, in Blocked Rotor Test, rotor of Induction Motor is blocked by external means so that it cannot rotate. The Blocked Rotor Test of Induction Motor is similar to the short circuit test of a transformer. As in Transformer short circuit test, we apply a voltage which can circulate … Read more
