LOSSES AND THE POWER FLOW DIAGRAM
Induction motors have been described as rotating transformers. The input is a three-phase system of voltages and currents. The secondary windings of the motor (the rotor) are shorted out. Figure 6.11 illustrates the relationship between the input electric power and the output mechanical power. The stator copper losses are I 2R in the stator windings. The core losses include the hysteresis and eddy currents losses.
