EXPERIMENTAL SECTION

EXPERIMENT-1

AIM

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

EQUIPMENT REQUIRED

Synchro Transmitter / Receiver Trainer kit.

☞Patch chords

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.

EXPERIMENT-2

AIM

To study the Rotor position of Synchro transmitter and Receiver

EQUIPMENT REQUIRED

Synchro Transmitter / Reciever module

☞Patch Chords

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.
