The total stray-load loss of a polyphase induction machine of the squirrel-cage type is given by the formula: WL = WC + WE + WSL1 + WSL2 + WZ + WB + WK (13) where the several items, except Wc, are given by equations 1, 7, 6, 9, 10, and 12. The sum of WE and Wc can be determined separately from the other losses by measuring the input to the stator when balanced polyphase currents are flowing, with the rotor removed, and subtracting from this the I2R losses calculated on the basis of the d-c… CONTINUE READING
