Abstract

The invention provides a monitoring method and a monitoring system of a motor. The monitoring system comprises the motor, a data acquisition device and a control device, wherein the data acquisition device is respectively connected with the motor and the control device. Firstly, the motor running time acquired by the data acquisition device in the whole working process from starting to a continuous stable running state and motor running parameters corresponding to the running time are adopted to draw real-time oscillograms of the running parameters; then the real-time oscillograms and running parameter values constantly corresponding to standard oscillograms and the like during normal motor running are compared to obtain variation tendency of the real-time oscillograms. Due to the fact that the running parameters correspondingly change before motor faults occur, the motor faults can be anticipated according to the variation tendency of the real-time oscillograms, and workers can take corresponding protective measures in advance.

Description

technical field [0001] The invention relates to the technical field of motors, and more specifically, to a monitoring method and a monitoring system for a motor. Background technique [0002] With the development and wide application of motors, the maintenance and maintenance of motors is becoming more and more important. At present, the current operating parameters of the motor are generally detected by the intelligent protector, and statistics are made on the past operating parameters and fault conditions of the motor, and then the operator takes corresponding protection measures according to the fault type, thereby reducing downtime and maintenance of lines and equipment Time, improve the reliability of the whole system work. [0003] However, the prior art can only take corresponding protective measures after the motor fails, and cannot prevent the motor from failing. Contents of the invention [0004] In view of this, the present invention provides a motor monitorin...
