Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0016] A magnetic assembly for a switch-type Hall sensor, comprising a piece of arc-shaped magnetic steel 2 and two pieces of magnetically permeable blocks 5 . The arc-shaped magnetic steel 2 is located in the middle, and is filled with magnetism in the radial direction; two magnetic blocks 5 are attracted to the two ends of the arc-shaped magnetic steel 2 respectively, and the magnetic block is not magnetized. A tile-shaped structure is formed between the two magnetic blocks 5 and the arc-shaped magnetic steel 2, and the arc-shaped magnetic steel 2 and the two magnetic blocks 5 are attracted together to achieve the use of magnetizing on one arc-shaped magnetic steel 2 Require.

[0017] There are two magnetization methods for the magnetic components of the switch-type Hall sensor. One of the magnetization methods is to make the outer arc...

Abstract

The invention discloses a magnetic component for a switch-type Hall sensor. The magnetic component comprises a magnetized arc magnetic steel which is positioned in the middle, each end of the arc magnetic steel attracts a non-magnetic conductive block, and a tile-shaped structure is formed between the two conductive blocks and the arc magnetic steel. The magnetic component overcomes the defects that two opposite polarities are difficult to be magnetized in the same magnetic steel and the critical surface of the position where the polarities are opposite is out of control. The magnetic component has the advantages that a magnetizing process is easy to control, the cost is low, and the percent of pass and the utilization rate of materials are high.

Description

technical field [0001] The invention relates to a magnetic assembly, in particular to a magnetic assembly applied to a Hall sensor. Background technique [0002] The Hall sensor is a magnetic field sensor made according to the Hall effect. According to the Hall effect, the element made of semiconductor material is called Hall element. Hall element has the advantages of sensitivity to magnetic field, simple structure, small size, wide frequency response, large output voltage change and long service life. Therefore, it is widely used in measurement, automation, computer, etc. And information technology and other fields have been widely used. [0003] Hall elements are generally divided into linear Hall elements and switching Hall elements. Among them, the linear Hall element moves and rotates in a uniform magnetic field, or the magnetic field moves and rotates around a fixed Hall element, and the Hall voltage of linear displacement and angular displacement can be generated, ...
