Which of the following motors is usually used in house-hold refrigerators ?
Correct answer: C. Single phase induction motor (split phase start or induction run motor)
- A. D.C. shunt motor
- B. D.C. series motor
- C. Single phase induction motor (split phase start or induction run motor)
- D. Reluctance motor
- E. Synchronous motor
Explanation
Household refrigerator compressors commonly use single-phase induction motors, especially split-phase or capacitor-start types, because they operate reliably from the domestic AC supply. DC and synchronous motors are not the usual choice for this application.
