text: We saw in Chapter 5 that when the induction motor is running at its normal speed, the rotating magnetic field that produces the currents and torque on the rotor also induced balanced 3-phase induced e.m.f's in the stator windings, the magnitude of the e.m.f's being not a great deal less than the voltage of the utility supply.
