A 3-phase slip ring motor has____________?
Correct answer: B. wound rotor
- A. double cage rotor
- B. wound rotor
- C. short-circuited rotor
- D. any of the above
Explanation
A slip-ring motor uses a wound rotor whose three-phase winding is connected to slip rings and external resistance. Double-cage and permanently short-circuited rotors belong to squirrel-cage motor constructions.
