Resolver type angle sensor

Abstract

The invention relates to a resolver type angle sensor which comprises a rotating shaft, a magnet and a detector. A detection circuit is arranged in the detector, and the axes of the rotating shaft, the magnet and the detector are located on the same straight line. An MLX90316 chip is arranged in the detection circuit, and the MLX90316 chip converts the change of the magnetic field into angle information. The sensor has the advantages of being low in cost and high in anti-interference performance.

Description

technical field [0001] The invention relates to the field of an anti-interference angle sensor, in particular to a rotary angle sensor. Background technique [0002] Angle sensors are widely used in automobiles, machinery, aviation, aerospace, navigation, industrial automation and other fields. It is mainly divided into two types: contact type and non-contact type. As the contact type angle sensor increases with the use time, there will be disadvantages such as mechanical wear, reduced accuracy, frequent maintenance or even replacement of new equipment, which not only increases the production cost but also increases the production cost. It is easy to make the quality of the device under test not guaranteed, and the non-contact angle sensor overcomes these shortcomings. Commonly used non-contact angle sensors are photoelectric and magnetoelectric. Although the precision of the photoelectric type is higher than that of the magnetoelectric type, it has strict environmental re...

Problems solved by technology

Although the precision of the photoelectric type is higher than that of the magnetoelectric type, it has strict requirements on the environment and poor shock resistance, so it is not suitable for industrial places with complex environments.
