# Lab Experiment for Synchro Transmitter and Receiver

## AIM

To measure the Stator output voltage with respect to rotor position and plot the graph.

## PROCEDURE

• Connect Digital Voltmeter across the any two Stator output of Synchro transmitter.
• Connect Synchro transmitter stator outputs to corresponding Stator terminals of Synchro receiver.
• Power ‘ON’ the all ON/OFF Switches
• Verify the Stator output voltage of 0V at 0 degree, if it is not make 0V at 0 degree toadjust the pointer of both transmitter and Receiver.
• Adjust the transmitter rotor position Step by Step.
• Now note down the output voltage for various rotor position in the table 1.
• Repeat the Same procedure for other pair of Synchro transmitter coils.

## Table-1

 SL. NO Synchro transmitter Rotor Position (degree) Stator Output (V)

## MOTOR GRAPH

The following table is used to Synchro transmitter Stator Output Voltage for variousRotor position.

 SL . No Rotor Position (degree) Stator Output (V) 1 2 3 4 5 0° and 180° 0° to 90° 90° to 180° 180° to 270° 270° to 360° 0V 0V to 40V 40V to 0V 0V to 40V 40V to 0V

## RESULT

Thus the Synchro transmitter Stator output voltage with respect to rotor position was studied and the graph was plotted.

## AIM

To study the Rotor position of Synchro transmitter and Receiver

## PROCEDURE

• Connect Digital Voltmeter across to the any two Stator output of Synchro transmitter.
• Connect Synchro transmitter stator outputs to corresponding Stator terminals of Synchro receiver.
• Power ‘ON’ the all ON/OFF Switches
• Verify the Stator output voltage 0V at 0 degree, if it is not make 0V at 0 degree toadjust the pointer of both transmitter and Receiver.
• Adjust the transmitter rotor position step by step by using knob
• Now note down the rotor position of transmitter and receiver in the table-2.

## Table-2

 SL.No Synchro transmitter Rotor Position (degree) Synchro Receiver Rotor Position (degree) Error = Rotor position (Transmitter - Receive

## RESULT

Thus the Rotor Position of Synchro. transmitter and Receiver was Studied.
