The equivalent circuit of a single-phase induction motor represents the machine as

  • A.two three-phase-like circuits in series, one per revolving field component
  • B.a single three-phase circuit with the slip halved throughout the whole of its length
  • C.a transformer with no rotor branch of any kind included
  • D.a purely resistive circuit with no reactance included at all

Answer: A

Each half-amplitude field gets its own rotor branch, one at slip \( s \) and one at slip \( 2 - s \), and the two are placed in series with the stator impedance. The difference between the two torques is the useful output.
