Working principle of swing coil

One, pendulum coil introduction

Also known as a wobbler, a wobbler coil is an electromagnetic component, usually made of a magnetic material with a wire around it. It is usually used to control switches and shield signals in circuits.

Two, the oscillator coil working principle

The pendulum is a device that uses the oscillation generated by electromagnetic induction, and its principle is to generate a periodic electromotive force through the change of the magnetic field, so as to drive the oscillation. When an electric current passes through a wire, a magnetic field is generated around it. When a wire is wound around a magnetic material, the magnetic field is caught and concentrated in the center of the material. When the pendulum coil is working, it will flow electricity into the coil, generating a magnetic field, so that the magnetic flux is generated inside the coil, resulting in a torque. At this time, the coil has the power to turn the rocker arm to complete the switch control and other functions.

Three, the use of pendulum coil precautions

1. Be careful not to exceed the rated current and rated voltage of the coil during use, otherwise it will cause the coil to overheat or burn out.

2. In the process of use, pay attention to the protection of the coil to avoid interference by external strong magnetic field, so as not to have adverse effects on the coil.

3. Pay attention to the contact problem of the coil when using the shaker coil, if the contact is poor, it will affect the working effect of the coil.

Four. Conclusion

Pendulum coil is a widely used electromagnetic component, according to its working principle, we can better understand the working process and use of the coil. In practical applications, it is necessary to pay attention to the rated current and voltage of the coil, protect the coil from external strong magnetic field interference, and pay attention to the contact problem of the coil.
