A household refrigerator typically uses a single-phase induction motor.
According to the provided references, a single phase induction motor is used in household refrigerators. More specifically, the Capacitor run motor is listed among the types of motors used in compressors, which are a core component of refrigerators.
Understanding the Motor Type
- Single-Phase Induction Motor: This is a common type of electric motor used in residential applications because household power is typically single-phase.
- Capacitor-Run Motor: This is a specific configuration of a single-phase induction motor that uses a capacitor in series with a start winding. This helps provide a starting torque and improves the motor's running efficiency. The reference specifically lists "Capacitor run motor" for "Refrigerators".
The table from the reference highlights the application:
| Single phase motor | Application |
|---|---|
| Split phase motor | Small drill presses, Shop grinders, Small belt-driven conveyors, Washing machine |
| Capacitor run motor | Compressors, Conveyors, Refrigerators, Air conditioners, Ceiling fans |
This indicates that while "single phase induction motor" is the general category, the "Capacitor run motor" is the specific type commonly employed in refrigerators to drive the compressor.
