Abstract

The invention discloses a multipole combined-type magnetic encoder which comprises a multipole combined-type magnetic grid and a signal processor, wherein the multipole combined-type magnetic grid is arranged in a shell and used for synchronously rotating along with a motor shaft, and three different magnetic fields are respectively generated on the multipole combined-type magnetic grid; and the signal processor is arranged in the shell and used for detecting a magnetic signal generated on the multipole combined-type magnetic grid, then converting the magnetic signal into high-resolution incremental-type A, B, Z electric signals and low-resolution absolute-type U, V, W electric signals and outputting . The multipole combined-type magnetic encoder has the advantages of high speed, small size and high resolution.

Description

technical field

[0001] The invention relates to the technical field of encoders, in particular to a multi-pole composite magnetic encoder. Background technique

[0002] With the development of motion control system, the transformation of DC motor to AC motor and the transformation of analog control to digital control are inseparable from encoders. The technical level of encoders directly affects the performance of motion control systems. As a kind of angular displacement sensor that converts the rotational angular position and angular velocity into electrical signals, there are many types, which can be divided into two categories: analog type and digital type according to the form of output electrical signal. Analog sensors include synchros, tachogenerators, etc., and digital sensors include optical encoders, magnetic encoders, etc.

[0003] At present, digital photoelectric encoders are widely used in industrial production, the technology is very mature, and the accuracy a...
