We now consider a motor in which the rotor receives its power not by conduction but by induction and is therefore called an induction motor. A winding that receives its power exclusively by induction ...
We saw in Chapter 6 that the induction motor can only run efficiently at ow slips, i.e. close to the synchronous speed of the rotating field. The best method of speed control must therefore provide ...
The electric whirl is in electrical contact ... These can also run on AC. The induction motor is the one that operates on perhaps the most interesting principle. The rotor is not electrically ...
