Synchro Transmitter Receiver Trainer (VPL-CL-STR)
DESCRIPTION
A Synchro Transmitter Receiver (STR) Trainer is an electromagnetic transducer commonly used to convert an angular position of a shaft into an electric signal. It is usually called a synchro transmitter. Its construction is similar to that of a three phase alternator. It consists of Sator, Rotor, Synchro Transmitter and Synchro Receiver.
- General Details
A Synchro Transmitter Receiver (STR) Trainer is an electromagnetic transducer commonly used to convert an angular position of a shaft into an electric signal. Its construction is similar to that of a three phase alternator. The stator (stationary member) is of laminated silicon steel and is slotted to accommodate a balanced three phase winding which is usually of concentric coil type (three identical coils are placed in the stator with their axis 120 degrees apart) and is Y connected. The rotor is a dumb bell construction and wound with a concentric coil. The system set up is made up of synchro transmitter and synchro receiver on a single rigid base provided with suitable switches and anodised angular plates. The system also contains a step down transformer for providing excitation to the rotors. Suitable test points for rotor (R1 and R2) and stator (S1, S2 and S3) for both Tx and Rx are provided.
