What are the two major components of a synchro?
2 Answers
A synchro is an electrical device used for converting angular position into an electrical signal, often utilized in systems for remote control, telemetry, and feedback mechanisms. The two major components of a synchro are:
### 1. **Rotor**
The rotor is the rotating part of the synchro. It consists of a coil wound around a core, which is usually made of ferromagnetic material. The rotor is mounted on a shaft that rotates according to the angular position being measured or controlled. When the rotor turns, it generates a varying magnetic field that interacts with the stator coils. The rotor is typically excited by an AC voltage, which induces a voltage in the stator windings based on the rotor's position.
### 2. **Stator**
The stator is the stationary part of the synchro and consists of multiple coils (usually three or more) arranged around the rotor. Each coil in the stator is connected to a different phase of the output signal. The stator's purpose is to detect the varying magnetic field produced by the rotor and convert it into an electrical signal. The voltages induced in the stator coils are proportional to the angular displacement of the rotor.
### Function and Operation
- **Operation Principle**: When an AC voltage is applied to the rotor, it creates a rotating magnetic field. As the rotor turns, this magnetic field varies in a sinusoidal manner, inducing voltages in the stator coils. The voltages generated in the stator coils are dependent on the rotor's angular position, and their relative magnitudes can be used to determine the exact position of the rotor.
- **Applications**: Synchros are commonly used in applications requiring precise position feedback, such as in aircraft navigation systems, radar systems, and other control systems where accurate angular measurement is crucial.
In summary, the rotor and stator are the two primary components of a synchro, working together to convert rotational position into an electrical signal that can be used for various control and measurement applications.
