A-26. The voltages are equal and oppose each other.
A-28. 1 and S3.
A-29. The rotor leads on either the transmitter or the receiver are reversed.
A-30. Differential synchros can handle more signals than regular synchros and also perform addition
and subtraction functions.
A-31. The TDX and the TDR.
A-32. Their application: a TDX has one electrical and one mechanical input with an electrical output.
A-33. The way the differential synchro is connected in a system is the deciding factor on whether the
unit adds or subtracts its inputs.
A-34. When the TDX rotor is on 0º.
A-37. The S1 and S3 leads are reversed between the TX and the TDX, and the R1 and R3 leads are
reversed between the TDX rotor and the TR.
A-38. The R1 and R3 leads between the TDR rotor and the TX to which it is connected.
A-40. A control synchro.
A-41. CX, CT, and CDX.
A-42. The CX and CDX have higher impedance windings.
A-43. The rotor is specially wound, it is never connected to an ac supply, and its output is always
applied to a high-impedance load.
A-44. They are perpendicular to each other.
A-45. The voltage is maximum and in phase with the ac excitation voltage to the CX.
A-46. Error signal.
A-47. When the CX and CT rotors are in correspondence.
A-48. To improve overall synchro system accuracy by reducing stator currents.
A-49. TDXs, CDXs, and Cts.
A-50. Magnetizing current.
A-51. They are delta-connected across the stator windings.
