magnetic encoder working principle

The basic principle of the magnetic encoder is detecting rotational movements as a magnetic field changesand considering them into electrical signals. And this magnetic tech is available in two types: off-axis and on-axis. Similarly, several benefits are available with this magnetic encoder that helps in various devices. The magnetic technology available in these sensors is more beneficial. The absence of contact helps to avoid wear, which improves the need fora new replacement of products. Heavy-duty applications that need high speed, robustness, and a different operating temperature rangeare the best option for this magnetic encoder.

Principle of magnetic encoders

The basic principle of the magnetic encoder starts from the rotation of the shaft. If the motor shaft rotates,the magnetic field of the natural magnet available at the tip of the shaft will also rotate. The magnetic field will be in revolution with excellent and stable strength at the rotation access. Then the hall element present in the system will detect the change in the magnetic field and convert them all into an electrical signal. The hall element present in this encoder is the magnetic sensor which detects only the magnetic field in a particular direction.

Though the magnetic field is in rotation, the encoder needs two hall elements to detect the magnetic field change on both the x-axis and y-axis. Then in the following process, the electric signal with the hall element will change them into angle information. The AD converter will convert all those details into digital data. So, these points deal with the basic principle and working process of magnetic encoders. All these points about the magnetic encoder will help understand this product’s working process.

Applications of magnetic encoders

Though the magnetic encoder works with a magnetic field, it will not have any damage while working in an environment that contains various kinds of dust, oil, and water. So, people can use these magnetic encoders in multiple machines that work in different locations with different issues. Due to its magnetic tech can work with all kinds of devices and industries,and it also helps users improve their work. The best example is the industrial sewing machine,which deals with various types of lint and engine oil,and it is also suitable for a device that works with splashing oil and water. Nowadays, many people started to use magnetic encoders instead of optical encoders due to their accuracy in working.

Conclusion

All these points about magnetic encoders will help the users understand the basic working principle of magnetic encoders. It also helps to know about the features and applications available with the encoders. So, people who need to understand the basic concepts of the magnetic encoder and its features should use this article to understand them. The devices that work with magnetic encoders help the users to get accurate results with remarkable features.
