Monitor of state of health of motor

Abstract

The invention discloses a monitor of the state of health of a motor. The monitor comprises a data acquisition unit, a data processing unit, a storage unit, a display unit and a transmission unit, thedata acquisition unit comprises a vibration temperature integrated sensor and used for measuring vibration of the motor and a bearing temperature, the data processing unit samples and processes data acquired by the data acquisition unit, the storage unit stores a vibration total value, a vibration frequency spectrum, an enveloping total value, an enveloping frequency spectrum and the bearing temperature obtained by processing of the data processing unit, the display unit displays the vibration total value, the enveloping total value and the bearing temperature obtained through acquisition andprocessing, and the transmission unit transmits the stored data to the outside in a wireless manner by employing automatic timed transmission or manual transmission. According to the motor, the vibration of the motor, the bearing temperature, and the damage state of bearing parts can be simultaneously monitored, and the state of health of the motor is expressed in a comprehensive manner through multiple parameters.

Description

technical field [0001] The invention relates to the field of motors, in particular to a motor health status monitor which expresses the health status of the motor by monitoring the vibration, bearing temperature and damage status of the bearing parts of the motor. Background technique [0002] The operating state parameters of the motor can be divided into two categories, one is the electrical state parameters, such as resistance, capacitance, current, voltage, power, power factor, etc., and the other is the mechanical state parameters, such as the vibration of the motor, bearing temperature, Damaged state of bearing parts and other mechanical states. The former represents the function index of the motor, and the latter represents the health index of the motor. The invention relates to the monitoring of motor health indicators. [0003] At present, the monitoring of motor health indicators in enterprises can only rely on hand-held instruments to obtain data such as motor v...

AI Technical Summary

Problems solved by technology

[0003] At present, the monitoring of motor health indicators in enterprises can only rely on hand-held instruments to obtain data such as motor vibration, bearing temperature, and bearing component damage. This method is affected by many factors such as human factors, technical level, and measurement conditions. It often fails to respond to the health status of the motor in a timely and accurate manner, causing motor failures and accidents to occur from time to time, bringing unnecessary losses to the enterprise and even affecting the normal production of the enterprise.
