🔍 Key Concepts

• Synchronous motor starting methods and why a synchronous motor cannot start by itself • Role of a damper (amortisseur) winding / squirrel cage on the rotor of synchronous machines • Difference between field excitation (DC) and induction-type currents in a squirrel cage

💭 Think About

• Think about what happens if you simply energize the stator of a synchronous motor with the rotor at standstill. Can it pull into synchronous speed on its own? Why or why not? • Which choice describes an induction motor behavior, and how is that related to a squirrel cage? • Which options describe functions that are associated with the DC field winding versus functions associated with damping or starting?

✅ Before You Answer

• Identify which option is clearly related to induction motor action rather than DC field excitation • Eliminate any option that describes something that mainly happens at synchronous speed rather than during the run-up from standstill • Make sure you separate the job of the DC field winding from the job of the squirrel cage / damper winding on the rotor
