Abstract

The invention discloses a motor health state monitor, which includes a data acquisition unit, a data processing unit, a storage unit, a display unit and a transmission unit; the data acquisition unit includes a vibration temperature integrated sensor for measuring the vibration and bearing temperature of the motor; The data processing unit samples and processes the data collected by the data acquisition unit; the storage unit stores the total value of vibration, vibration spectrum, total envelope value, envelope spectrum and bearing temperature obtained through the processing of the data processing unit; the display unit stores the collected , the processed vibration total value, envelope total value, and bearing temperature are displayed; the transmission unit transmits the stored data to the outside world in a wireless manner, and adopts automatic timing transmission or manual transmission. The present invention can simultaneously monitor motor vibration, bearing temperature, The damage state of the bearing components, multi-parameters comprehensively express the health state of the motor.

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...
