🔍 Key Concepts

• Synchronous motors normally have no inherent starting torque • Purpose of a damper (amortisseur) winding in large AC machines • Difference between excitation and mechanical starting behavior

💭 Think About

• Think about what happens if you connect a synchronous motor directly to the AC supply: how does it get from standstill up to synchronous speed? • What kind of winding is used in an induction motor to create torque at standstill, and how is the damper winding similar? • Which option relates to the motor’s behavior during starting and transients, rather than steady‑state operation at synchronous speed?

✅ Before You Answer

• Verify that synchronous motors cannot start by themselves without some additional feature or external help • Check which option describes a function needed only at startup and during speed changes, not during normal synchronous running • Confirm that excitation is normally supplied by a DC field winding or AVR, not by the damper winding
