Abstract
The utility model relates to a many rings of encoders based on hall sensor belongs to many rings of encoders. Two bearings of installation in the encoder main part, bearing inner race is connected with the main part, bearing inner race and encoder hub connection, the code wheel is installed at the encoder epaxially, and the PCB board is installed in the main part, its characterized in that: a circular magnet is installed integratively with the encoder axle for producing magnetic field, circular magnet is concentric with the encoder axle, have on the PCB board with the concentric hall sensor who places of circular magnet, one coil data acquisition unit is located the PCB board. The advantage is novel structure, with a rotary magnet, many rings of tally functions of a hall sensor realization, combines one coil data acquisition unit to realize the function of many rings of encoders, and the counting principle is simple, has realized the synchronization of one coil and many number of turnss certificate, has improved the reliable line of system, has reduced the complexity.
Description
Technical field
This utility model belongs to a kind of encoder.
Background technology
Multi-turn absolute value encoder enables to the measurement scope of individual pen absolute value encoder and strengthens so that the function measuring individual pen position of rotation extends to measure rectilinear movement distance.The number of turns counting mode of encoder is various, mainly based on gear structure.Owing to gear structure, while adding encoder own wt, the accuracy of counting also depends on gear part and the corresponding machining accuracy separating code-disc, and the labyrinth that gear structure brings also brings the problem that product reliability is low.
Summary of the invention
This utility model provides a kind of encoder based on Hall element, to solve the problem that structure is complicated, reliability is low using gear structure counting mode to exist.
This utility model adopts the technical scheme that: install two bearings in encoder main body, bearing outer ring is connected with main body, bearing inner race is connected with encoder axle, code-disc is arranged on encoder axle, pcb board is installed in main body, and integrally mounted with encoder axle for producing the circular magnet in magnetic field, described circular magnet is concentric with encoder axle, having the Hall element placed concentric with circular magnet on pcb board, individual pen data acquisition unit is positioned on pcb board.
Within circular magnet described in the utility model is installed on encoder axle or is arranged on encoder axle.
The utility model has the advantages that novel structure, multi-turn tally function is realized with one block of rotary magnet, a Hall element, the function of encoder is realized in conjunction with individual pen data acquisition unit, counting principle is simple, achieve the synchronization of individual pen and multi-revolution data, improve the reliable rows of system, reduce complexity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of this utility model circular magnet.
