Challenge Problems
Push your limits with challenges.
Question 1
A single-phase washing machine motor uses the split-phase method. If the main winding requires a current of 5 A to start, what will happen if only the auxiliary winding is energized?
💡 Hint: Think about the function of both windings in achieving torque.
Question 2
If a capacitor-start motor is designed for a starting torque of 15 N·m, what criteria must the capacitor meet to ensure effective operation?
💡 Hint: Consider the role of the capacitor in modifying the phase difference.
