An induction machine is described as singly excited because

  • A.only its stator is connected to a supply
  • B.it has only one winding in total
  • C.its rotor is excited by a separate direct supply
  • D.it operates only on a single-phase supply

Answer: A

The rotor current is induced by the revolving field rather than supplied, which is what makes the cage rotor possible and the machine so simple. A synchronous machine is doubly excited, with direct current fed to its rotor.
