Embodiment 1

[0016] The absolute multi-turn magnetic encoder includes a housing 1 , a main shaft 8 , a metal code disc 12 , a magnetic sensor and a data processing unit 6 . The metal code disc 12 is fixed on the main shaft 8 through the sleeve 9, and rotates with the main shaft 8. The magnetic steel 13, the magnetic sensor 10, and the magnetic sensor 11 are respectively installed on the printed circuit board 2 and the printed circuit board 4 on both sides of the metal code disc 12. The number of them is determined by the number of slotted circles of the metal code disc 12. The printed circuit board 2 and the printed circuit board 4 are fixed together with the housing by the snap ring 3 and the snap ring 5. They do not rotate with the main shaft and are used to detect the metal code. The position where the disk has been rotated; the data processing unit 6 is installed on the back cover 7, and the data processing unit 6 is connected with the magnetic sensitive element 10 and the magnetic sens...

Abstract

The invention relates to an absolutely multi-turn magnetism coder. The metal coding disc is distortion round disk shape. And four arcs are set on the radial direction, two opposite side of the same radius has tow arcs, and the third arc is between the next one side, and the fourth arc is set on another side. The coder is simple structure, few components, long useful life, high reliability, etc.

Description

technical field [0001] The present invention relates to magnetic encoders. Background technique [0002] An encoder is a displacement sensor that converts physical quantities such as rotational angular position, angular displacement, and angular velocity into electrical signals. With the development of factory automation, the change of DC motors to AC motors and the transition from analog control to digital control, the encoder has shown its superiority, and its demand has skyrocketed. According to different measurement methods, encoders are divided into incremental and absolute. The absolute encoder has the advantages of being able to detect the absolute position at any time, strong anti-interference ability, and the accumulated error caused by noise is zero, and its application demand is increasing year by year. Especially the absolute multi-turn encoder has a wide measurement range and can accurately record the rotation of the measured shaft even if the power is off. It...
