induces a large voltage – hence  large currents flow within the             rotor,                          22

The difference between thesynchronous speed and rotor        speed can be                      25
expressed as a percentage ofsynchronous speed, known as         the slip.                       26

s = slip, Ns = synchronousspeed (rpm), N = rotor speed            (rpm)                       29
• At no-load, the slip is nearly        zero (<0.1%).                           30
