Final answer:
Split phase motors are classified into Resistance Split-Phase Motor, Capacitor-Start Motor, Capacitor-Start Capacitor-Run Motor, and Permanent-Split Capacitor (PSC) Motor, each using different methods to create phase shift between windings necessary for their operation.
Step-by-step explanation:
Split phase motors are a type of single-phase induction motor distinguished by the use of two separate windings to start and run the motor. These motors have various classifications based on how the windings are utilized during the motor's operation. Four common classifications of split phase motors include:
- Resistance Split-Phase Motor
- Capacitor-Start Motor
- Capacitor-Start Capacitor-Run Motor
- Permanent-Split Capacitor (PSC) Motor
Each type has a different method of creating the necessary phase shift between the start and run windings, which is essential for the motor's operation. For example, Resistance Split-Phase Motors use a non-polarized starting winding with a higher resistance to create the phase shift, while Capacitor-Start Motors use a starting capacitor in series with the starting winding. Capacitor-Start Capacitor-Run Motors utilize both a start and run capacitor for improved efficiency, and Permanent-Split Capacitor (PSC) Motors use a run capacitor that remains in the circuit during both start and run modes, providing a quiet and reliable performance.
