Description

Stepping motor of encoder

Technical Field

The utility model relates to an intelligence transmission technical field specifically is an encoder step motor.

Background

When step motor is after the circular telegram, the drive plate is to step motor signals, step motor's output shaft can rotate and drive other structure work, but current step motor can't make the judgement to the actual rotation condition of output shaft and compensate, for example, when stepping motor rotates 100 steps as required, can't judge whether step motor actually rotates 100 steps, lack the feedback device to step motor promptly to the error rate that can't judge step motor work is how much to make step motor's precision high inadequately.

Therefore, the utility model provides an encoder step motor.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough to prior art exists, the utility model aims at providing an encoder step motor, with the problem that proposes in solving above-mentioned background, the utility model discloses an at step motor's output installation axis of rotation, install the response magnetite in all sides of axis of rotation, at step motor side-mounting drive plate, through electric wire installation high accuracy detection chip between response magnetite and drive plate, step motor just carries out the problem of work according to the instruction that the drive plate sent before can solving, realize the mistake to step motor actual behavior, and feed back it to the drive plate, compensate step motor, reach servo motor's effect, and this step motor is small, be applicable to the intelligent transmission field of high accuracy requirement.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1 and fig. 2, the present invention provides a technical solution: the utility model provides an encoder step motor, includes shell 1, the built-in step motor 2 that is equipped with of shell 1, the output of this step motor 2 is fixed with axis of rotation 3, and response magnetite 4 has been installed to the week side of axis of rotation 3, and step motor 2 one side is installed and is equipped with drive plate 6 corresponding with step motor 2, and has the high accuracy to detect the chip through the connection of electric lines between the input port of response magnetite 4 and drive plate 6.

This embodiment, set up induction magnet 4 into annular structure, and axis of rotation 3 and annular structure are coaxial, have installed backshell 5 in 1 one side of shell, and drive plate 6 is located backshell 5, and through the bolt fastening between shell 1, backshell 5 and the step motor 2, when step motor 2 drives 3 rotations rounds of axis of rotation, high accuracy detection chip detects 1024 or 4096 signals through induction magnet 4, through the connection of electric lines between the delivery outlet of step motor 2 and drive plate 6.

When step motor 2 during operation, at first set for step motor 2's behavior through drive plate 6, if set for step motor 2 and rotate to 100 steps, step motor 2's output rotates, thereby drive axis of rotation 3, response magnetite 4 detects the number of turns of rotating, every time axis of rotation 3 rotates the round, high accuracy detects the chip and detects 1024 or 4096 signals through response magnetite 4, then will transmit it for drive plate 6, if step motor 2's rotation number does not reach 100 steps, drive plate 6 judges the signal that high accuracy detected the chip and carried, then drive plate 6 control step motor 2 carries out compensation work.
