by

Parameters do we get From no Load Test and Blocked Rotor Test on 3 Phase Induction Motor and Flow

Q. What data /parameters do we get from no load test and blocked rotor test on 3 phase I.M. and flow ?

No load test : 

We get from no load test

  1. No load current and its components 
  2. Magnetising circuit constants
  3. Iron loss 

Blocked rotor test on 3 phase Induction Motor: 

Blocked rotor test we get 

  1. Copper loss 
  2. Z01,  R01  and  X01
  3. We can plot equivalent circuit and circle diagram to find complete performance of motor.
