Synchros Interview Question Answer


1
State the different types of Synchros.


Types of Synchros
  • Control transmitter
  • Control receiver
  • Control transformer
  • Control differential : Control differential transmitter and control differential receiver


2
Which type of stator and rotor construction the control transmitter consists of?


Control transmitter
  • Stator : It has three phase winding similar to that of induction motor.
  • Rotor : It has projecting poles


3
Describe the principle of operation of control transmitter


Principle of control transmitter
  • The control transmitter works on the transformer principle.
  • It consists of three phase stator winding on the stator and single phase rotor winding on the projecting poles.
  • When the rotor winding is energized, it produces alternating flux which induces unbalanced voltage in the stator winding.
