Synchros Flashcards
When a ship turns from hard port to hard starboard or vice verse what is that called?
Rudder Rate
What are the 2 types of damping?
Electrical and Mechanical, electrical is more used
What are the only 2 leads that can be switched for opposite direction?
S1 and S3
When a ship turns from hard port to hard starboard or vice verse what is that called?
Rudder Rate
What are the 2 types of damping?
Electrical and Mechanical, electrical is more used
______ volts is the max voltage induced into any one stator coil
52 volts
If a synchro is reading 180° difference what 2 leads are reversed?
R1 and R2
Synchros are used primarily for the _________ and _________ transmission of information between equipment and stations?
Rapid and accurate
What’s the difference between a torque and a control synchro?
Torque synchros are used for light loads, control are used to move heavy loads.
What are the 2 types of synchros?
Torque and control
On the Synchro schematic symbol what indicates the angular displacement of the rotor?
The position of the arrow
What are the 2 parts of a synchro?
Rotor and stator
What unit of measurement is used when referring to the torque of a synchro transmitter?
Ounce-inches
Never hook a 400 HZ up to a 60 HZ voltage, it will burn out the synchro
No answer, just a reminder!
A synchro resembles a small electrical motor in size and appearance and operates like a _______?
Variable transformer
What principle is a synchro based upon?
Electromagnetic induction
What determines the type of synchro to be used in a system?
The type of load placed on the synchro
Military standard synchros are designed to operate at _____ volts AC and _____ volts DC?
115/26
_____ volts is predominately used on synchros for shipboard use?
115VAC
What is the most accurate way of zeroing out a synchro?
AC voltmeter method
What’s the fastest method of zeroing out synchros, typically on TR because the shaft is free to turn?
Electrical lock method
With a properly zeroed synchro what should you read between S1 and S2 with your voltmeter?
0 volts
How many categories of synchros are there?
Two
Synchro construction can be described as what 2 parts.
Stator and Rotor
What components ma up a single torque synchro system?
A torque transmitter (TX) and a torque receiver (TR)
