Comprehensive evaluation system and evaluation method for motor design

Abstract

The invention belongs to the technical field of motor design evaluation and discloses a comprehensive evaluation system and evaluation method for motor design. The system comprises a data collection module for converting an obtained analog quantity electrical signal into a digital quantity signal and sending the digital quantity signal to a main control module, a rotary speed detection module connected with the data collection module and used for performing real-time detection on a rotary speed of a motor, an electromagnetic information collection module connected with the data collection module and used for performing real-time detection on electromagnetic information of the motor, and a main control module connected with the data collection module, a fuzzy comprehensive evaluation moduleand a display module and used for performing comprehensive evaluation on the motor through the fuzzy comprehensive evaluation module according to motor parameter data collected by the data collectionmodule. The system is high in reliability and high in operability; an evaluation result can reflect motor design engineering practice more objectively and really; the designed motor can be subjectedto comprehensive evaluation more comprehensively, more accurately, more effectively and more reasonably; and relatively good guiding opinions can be provided for designers.

Description

technical field [0001] The invention belongs to the technical field of motor design evaluation, in particular to a comprehensive evaluation system and evaluation method for motor design. Background technique [0002] At present, the safety assessment of in-service motors mostly adopts a single-angle evaluation method, and the conclusion whether the in-service motors can work safely is drawn from the theoretical aspect, and it cannot solve the problem of its safety degree by integrating various factors. The details are as follows: the detection and quantification of defects are inaccurate; the single-angle evaluation method relies too much on field data, and cannot comprehensively consider all the main factors that affect the safety of motors in service, and clarify the interrelationship of each impact, which is inconsistent with the actual situation The result of the evaluation is only a theoretical conclusion on whether it can work safely, and it cannot solve the problem of...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the traditional motor design comprehensive evaluation system adopts a single-angle evaluation method, which cannot comprehensively consider all the main factors that affect the safety of motors in service, and clarify the interrelationships of each impact. The actual situation does not match; at the same time, the acquisition unit only has the motor speed detection circuit and the current and voltage detection unit, which only evaluates the speed performance and current and voltage state of the motor, but does not consider the electromagnetic information and process information of the motor that play an important role in the motor design. collect and evaluate

It can be seen that the traditional motor design comprehensive evaluation system fails to conduct a comprehensive, accurate and reasonable comprehensive evaluation of the designed motor.
