Electrical Engineering · Single Phase Induction Motors
Compared to a split-phase induction motor, how does a capacitor-run motor achieve higher efficiency and better running performance?
- 1By increasing the number of stator poles
- 2By using heavier gauge copper windings
- 3By maintaining a phase angle closer to 90° between main and auxiliary winding currents during operation✓
- 4By disconnecting the auxiliary winding after reaching full speed
Correct answer
By maintaining a phase angle closer to 90° between main and auxiliary winding currents during operation
