Challenge Problems

If a capacitor-start motor draws 10 A during starting and produces a starting torque of 30 Nm, while a split-phase motor draws 5 A and produces 10 Nm, explain how the capacitor impacts the performance and application of each motor.
💡 Hint: Consider how the phase shift translates to torque.
In a design scenario, you have two motors: a split-phase motor rated at 1/3 HP and a capacitor-start motor rated at 1/2 HP. If they both operate at the same efficiency, compare their expected starting torques.
💡 Hint: Evaluate how HP and torque relate.
