🔍 Key Concepts

• Review how a synchro transmitter and indicator use three-phase (R1, R2, R3) stator leads and two (S1, S2) rotor/slip-ring leads. • Think about what kind of fault would cause erratic or intermittent motion, versus a steady error in angle. • Compare the wiring shown under the transmitter and indicator in part C of the illustration, paying attention to which terminals go to slip rings and which are fixed connections.

💭 Think About

• Is erratic operation more likely to come from a problem with a moving, rotating connection, or from a steady change in supply voltage? • If a three-phase voltage supply were uniformly low or high, how would the indicator behave—erratically, or just weaker/stronger but smooth? • Look at labels R and S in the circuit: which one represents the rotor/slip rings and which one represents the stator connections, and which of those is physically more prone to intermittent contact?

✅ Before You Answer

• Confirm which leads in the diagram are tied to the slip rings (rotor) and which are the fixed stator (three-phase) connections. • Decide whether voltage level issues typically cause intermittent/erratic motion or a consistent, proportional error. • Match the choice that associates intermittent contact with the correct combination of slip rings and stationary connections, based on the diagram.
