Abstract

A multi-antipode magnetoelectric encoder dynamic multi-window interval prediction angle subdivision method is used for accurately determining a number of poles corresponding to a multi-antipode angleof the magnetoelectric encoder; the method comprises the following steps: 1, parsing a single antipode and multi-antipode magnetoelectric encoder angle value; 2, building dynamic multi-window according to the multi-antipode magnetoelectric encoder angle value; 3, parsing a pole number corresponding to the multi-antipode angle value of the encoder according to the dynamic multi-window; 4, subdividing the multi-antipode magnetoelectric encoder angle value according to the dynamic multi-window, the single-antipode angle value and the multi-antipode angle value.

Description

technical field [0001] The present invention generally relates to a magnetoelectric encoder, in particular to a method for subdividing the dynamic prediction window angle of a multi-pole magnetoelectric encoder. Background technique [0002] With the accelerated development of industrialization, there are higher requirements for the resolution and accuracy of angular displacement sensors. At present, magnetoelectric encoders and photoelectric encoders are widely used as angular displacement sensors. Photoelectric encoders have high precision, but are bulky and fragile. Relatively speaking, magnetic encoders can work in dusty and oily environments, but the resolution is difficult to improve. In order to improve the precision of the magnetoelectric encoder, scholars have done a lot of research. The commonly used magnetoelectric encoder structure usually includes a stator, a rotor and a sensor, and a permanent magnet is fixed on the rotor to form a magnetic circuit system. ...
