Abstract

The invention discloses a system for testing automatically electric machine performances and a method for working, which are based on virtual instruments and characterized in that the invention is composed of a parameter presetting portion, a data collecting portion, a data displaying portion of a microcomputer data managing module which contains testing software. Working methods of the invention are that parameter presetting, data collection, signal adjustment, data comparison, and results display. Superiorities of the invention lie in that starting, stopping, and automatic collection and testing of data can be finished automatically, data processing and parameter calculation can be proceeded automatically, whole testing process can be controlled by a computer procedure, testing functions of each testing project can be changed through changing the computer procedure, data is collected in a fast speed, simultaneity of testing data can be guaranteed, errors due to manual reading can be avoided, testing accuracy is high, repeatability is good, time and labor can be saved greatly, testing efficiency can be increased greatly, and reliability is high.

Description

(1) Technical field: [0001] The invention belongs to the field of virtual technology, in particular to a virtual instrument-based automatic motor performance testing system and a working method thereof. (two) background technology: [0002] The motor is the most important machine to realize electromechanical energy conversion or change the characteristics of electrical energy. In recent years, with the rapid development of the national economy, the demand for motors in all walks of life is increasing, and higher indicators are put forward for the performance and quality of motor products. Whether the selection of the test system is reasonable or not is directly related to the performance of the forming motor. How to use a suitable test system to accurately test the relevant performance of various motors, analyze the data of the test process, and then determine the pros and cons of the product performance, so as to improve the relevant The production process has become a hot...
