Marine - Shipboard Synchro's, Torqsyns & Servo Motors

Description:

Synchros, Torqsyns and Servo Motors are used extensively throughout the ship in Transmission and Servo Systems to transmit ship’s parameter data to remote locations as required.

Synchro

Synchros as identified by the Armed Forces, are electromagnetic devices which have certain characteristics and are used primarily for the transfer of angular data. Synchros are in effect transformers whose primary-to- secondary coupling may be varied by physically changing the relative orientation of the two windings. Aboard ship, radar antennas, gun turrets, sonar projectors, rudder and other devices whose positions are variable can have their position data transmitted by synchro to remote control and observation points.


Torqsyn

A torqsyn’s function and application are similar to a Synchro. The torqsyn incorporates a high efficiency continuous rotation DC torque motor and a synchro control transformer mounted on a single shaft, with all necessary electronics in a compact case.

AC Servo Motor

AC servo motors are used primarily to move light loads. Most of the AC servo motors are of the two phase or split phase induction type. Fundamentally these motors are constant speed devices although their speeds can be varied within limits by varying the amplitude of the voltage to one of the stator windings.

DC Servo Motor

The control characteristics of DC servo motors are superior to those of AC servo motors. The DC servo motor is designed to control heavy loads at variable speeds.


Types:

Military Standard Synchro types are shown below:

FUNCTIONAL CLASSIFICATION ABBREVIATION INPUT OUTPUT

Torque Transmitter

TX

Mechanical input to rotor (rotor energized from AC source.)

Electrical output from stator representing angular position of rotor to TDX, TDR, or TR.

Control Transmitter

CX

Same as TX

Same as TX except it is supplied to CDX or CT.

Torque Differential
Transmitter

TDX

Mechanical input to rotor, electrical input to stator from TX or another TDX.

Electrical output from rotor representing algebraic sum or difference between rotor angle and angle represented by electrical input to TR, TDR, or another TDX.

Control Differential
Tranmitter

CDX

Same as TDX except electrical input is from CX or another CDX

Same as TDX except output to CT or another CDX.

Torque Receiver

TR

Electrical input to stator from TX or TDX (Rotor eneregized from AC source.)

Mechanical output from rotor note: rotor has mechanical inertia damper.

Torque Differential
Receiver

TDR

Electrical input to stator from TX or TDX, another electrical input to rotor from TX or TDX.)

Mechanical output from rotor representing algebraic sum or difference between angles represented by electrical inputs. Has inertia damper.

Control Transformer

CT

Electrical input stator from CX or CDX, mechanical input to rotor.

Electrical output from rotor proportional to the size of the angle between rotor position and angle represented by electrical input to stator. Called error signal.
