CHAPTER 1
SYNCHROS
LEARNING OBJECTIVES
Learning objectives are stated at the beginning of each chapter. These learning objectives serve as a
preview of the information you are expected to learn in the chapter. The comprehensive check questions
placed throughout the chapters are based on the objectives. By successfully completing the Nonresident
Training Course (NRTC), you indicate that you have met the objectives and have learned the information.
The learning objectives for this chapter are listed below.
Upon completing this chapter, you will be able to:
1. Define the term "synchro."
2. State the primary purpose of a synchro.
3. Explain the importance of synchros in naval equipment.
4. Name the two general classifications of synchros.
5. Explain the differences between torque and control synchros.
6. Name the seven functional classes of synchros and list all inputs and outputs.
7. Name the two types of synchro identification codes.
8. Interpret all synchro markings and identify the particular codes used.
9. Draw the five standard schematic symbols for synchros and identify all connections.
10. Describe the general construction and physical appearance of synchro rotors and stators.
11. Name the two common types of synchro rotors, giving an application of each.
12. List the different synchro characteristics and give a brief explanation of each.
13. State the advantage of using 400-Hz synchros over 60-Hz synchros.
14. Explain the operation of a basic synchro transmitter and receiver.
15. State the difference between a synchro transmitter and a synchro receiver.
16. List the basic components that compose a torque synchro system.
17. Explain the operation of a simple synchro transmission system.
18. Define the term "correspondence" and explain how it is used in a simple synchro system.
19. Explain the principle behind reversing the S1 and S3 leads on a synchro receiver and how this
action affects receiver operation.
