How an Induction Motor Works by Equations (and Physics)
www.brown.educurrent to be driven into the rotor windings from any direct connection. (A direct connection would require brushes, a commutator and more power supply connections, raising cost and decreasing reliability. This is why induction motors are more popular.) Instead the rotor is wound with shorted turns in which the environmental field induces a ...
