Testing tool for SSI encoder

Abstract

The invention relates to the SSI encoder field, discloses a testing tool for an SSI encoder. The testing tool comprises a motor, a coupler, upper computer software and an execution unit, wherein the execution unit comprises an STM32H750 single-chip microcomputer, an alarm and an MAX485 communication interface chip; the coupling is connected with the motor shaft extension end through interference fit, and the SSI encoder shaft extension end is fixedly connected with the coupling. The testing tool is high in universality, simple in circuit and low in cost, automatic recording and automatic judgment can be achieved, manpower is saved, the data correctness is improved, and data storage and query are facilitated.

Description

technical field [0001] The invention relates to the field of SSI encoders, in particular to a testing tool for SSI encoders. Background technique [0002] With the continuous development of science and technology, my country's industrial automation industry has achieved long-term development, which has driven the continuous innovation of supporting parts. Among them, the SSI encoder plays a pivotal role in the precise operation of the motor. When working, the motor drives the SSI encoder to rotate at high speed, and the SSI encoder converts the angular displacement or linear displacement into an electrical signal, which is then fed back to the controller. The value detected by the SSI encoder directly affects the operation of the motor. So it is necessary to test the performance of the SSI encoder before installation. [0003] In the traditional SSI encoder test method, it is necessary to manually observe the value displayed in the SSI encoder instrument and the waveform p...
