Figure 1-7A.—Typical stator.
Figure 1-7B.—Stator lamination.
Now, refer to figure 1-4 for a view of a completed synchro assembly. The rotor has been placed in
the stator assembly, and a terminal board has been added to provide a point at which internal and external
connections can be made.
Q-9. What are the two major components of a synchro?
Q-10. Which of the two main types of rotors can have either a single winding or three Y-connected
windings?
Q-11. How does the stator receive its voltage?
Q-12. Where are the external connections made on standard synchros?
SYNCHRO CHARACTERISTICS
Synchro characteristics play a very important part in synchro troubleshooting and maintenance. By
closely observing these characteristics, you can generally tell if a synchro or synchro system is working
properly. Low torque, overheating, and improper operating voltages are just a few of the abnormal
