Abstract
An analytical approach to calculate the stray load losses of cage induction machines at sinusoidal supply is compared with input-output measurements according to IEC 61972, which complies with the new standard IEC 60034-2, 4.0 ed. under preparation. The analytical approach allows the calculation of losses in the stator winding due to current displacement, due to harmonic rotor and inter-bar currents, due to tooth flux pulsations and eddy currents in the rotor surface, at any given slip, load and saturation level. Calculation and measurements are compared for 4-pole TEFC standard induction motors 1.1 kW, 11 kW, 75 kW and 110 kW.
