WebFor Watt calculation formula: P(W) = V(V) x I(A) in watt. P(MW) = V(V) x I(A) /100000 in megawatt. For Calculating DC motor output power, we need to multiple above formulae with motor efficiency. Note: The voltage V (V) to be measured between the armature terminals and DC current I (A) will be the armature current. WebRotor Copper Loss - (Measured in Watt) - The rotor copper loss is the value that you get while subtracting the stator copper loss from the total measured loss. Slip - Slip in Induction Motor is the relative speed between the rotating magnetic flux and rotor expressed in terms of per unit synchronous speed. It is a dimensionless quantity. Rotor Input Power - …
