Title Multi-parameter test method for ultrasonic motors
Abstract
Before officially put into operation and entering the market,the output speed range, torque range, repeat accuracy , noise, life and other parameters of ultrasonic motor must be measured and demarcated.Otherwise,it is easily to make the ultrasonic motor not working properly,or even damage to the user’s equipment.Therefore, the parameters of ultrasonic motor must be measured and demarcated, this article has designed a complete ultrasonic motor parameter test system.
The test system consists of ultrasonic motor speed tests, corner test, repeat positioning accuracy of the test, positive test, torque test, and other subsystems,use photoelectric encoders, photoelectric door and grating disk as sensor.First, design the multi-parameter test system’s hardware for ultrasonic motor, by comparing the advantages and disadvantages of various types of hardware, determine the hardware required to use in this test system, and install and fix part of the hardware.Then using LabVIEW programming language to write test software of the test system, the test software is mainly used to capture waveform signals that photoelectric encoder and the other sensors outputted, including the data processing and analysis, the results show and other content. Finally, get the error evaluation of the measured data, and analyze the reasons for the error, and propose appropriate measures to reduce the error.
