In three-phase squirrel-cage induction motors____________?
Correct answer: B. rotor conductors are short-circuited through end rings
- A. rotor conductor ends are short-circuited through slip rings
- B. rotor conductors are short-circuited through end rings
- C. rotor conductors are kept open
- D. rotor conductors are connected to insulation
Explanation
In a squirrel-cage rotor, conducting bars are permanently joined at both ends by end rings, forming a closed electrical path. Slip rings are used in wound-rotor motors, not squirrel-cage motors.
