Embodiment Construction

[0018] The present invention will be further explained below in conjunction with specific embodiments, but the present invention is not limited thereto.

[0019] Such as Figure 1-5 As shown, the present invention provides a split encoder with an automatic calibration function, including: an encoder read head 101, a detection magnetic block, a calibration button 105 and a cable 104, the encoder read head 101 and the detection magnetic block It is a separate body and is used to output analog voltage signals. The calibration button 105 is located at one end of the upper surface of the encoder read head 101 and is used to calibrate the gain, phase, offset and other parameter values ​​of the analog signal output by the reluctance. The cable 104 is located at the other end of the upper surface of the encoder read head 101, and is used to transmit the calibrated pulse signal, wherein the detection magnetic block is set on the drive shaft of the motor, wherein the encoder read head 1...

Abstract

The invention discloses a split type encoder with an automatic calibration function. The split type encoder comprises an encoder reading head, a detection magnetic block, a calibration key and a cable; the encoder reading head and the detection magnetic block are split and used for outputting an analog voltage signal; the calibration key is positioned at one end of the upper surface of the encoderreading head; and the cable is positioned at the other end of the upper surface of the encoder reading head. The split type encoder with the automatic calibration function is higher in output signalprecision, not prone to code loss, high in reliability, low in installation precision requirement, small in occupied space, convenient to install and detach, not limited to the size of a motor shaft,capable of achieving higher rotating speed and reducing the load of the motor shaft, small in heating value, not prone to damage, easy to operate, high in reliability, does not need to be calibrated before leaving a factory and is easy for batch production.

Description

technical field [0001] The invention relates to the field of encoders, and in particular provides a split encoder with an automatic calibration function. Background technique [0002] An encoder (encoder) is a device that compiles and converts signals (such as bit streams) or data into signal forms that can be used for communication, transmission and storage; in practical applications, encoders often encounter motor shafts with infinite size or require When the speed is very high, the advantage of the split encoder is great. The split encoder is fixed by separating from the gear or magnetic ring, and installed on the motor shaft through the gear or magnetic ring. The size can be infinite, and the split encoder It occupies a small space and is very convenient to install and disassemble. [0003] However, the existing split encoders have very high requirements on the installation position. It is necessary to completely align the split encoder with the gear or the magnetic rin...
