1. Explain why a starting method is needed in motors taking the equivalent circuit of a DC motor into consideration. 2. Why are induction motors preferred over DC motors in the industry? 3. What is the main difference between a synchronous machine and an induction machine? 4. What is the advantage of slotting? 5. If the slip of an induction machine is 0, would it be operating as a motor or as a generator? Explain 6. Explain why the power factor of an induction motor changes when the slip changes.
