IIoT platform for motor quality analysis

June 2018 Maintenance, Test & Measurement, Calibration

Motors drive industry and provide convenience in everyday life. However, if they are not maintained they can fail, which will interrupt production, affect revenue, energy efficiency and product quality, and could also result in safety hazards. This invariably causes an increase in the cost of production.

The IIoT Motor Diagnostic System accurately diagnoses the state of equipment in real time and automatically notifies users of problems as well as solutions. It analyses the voltage and current signals supplied to the motor. To do this, users need only connect a sensor between the motor and the distribution board. The diagnostic system analyses the current state of the motor and makes estimations about its health. The system runs a comparison analysis between the measured data from the motor and that of the line motor database. It picks up even slight differences and analyses them to diagnose abnormalities and then gives advance notice in real-time of possible impending failure.

The system has a periodic notification function that evaluates the performance of the motor at set intervals and informs of possible maintenance risks and estimated time to replace parts. It is installed in the motor control panel and results are analysed automatically. It is easy to use and can conveniently be managed remotely as well. The IoT Motor Diagnostic System detects both electrical and mechanical faults of various types in industrial equipment, driven by three-phase electric motors.

Additionally, it is also capable of detecting abnormalities of the connecting cable and terminal blocks, as well as changes in the load and supply. Hence the system allows users to observe in real-time whether the motor is performing optimally.

Motors that consume the most power in the industrial field often run at low efficiency during long-term operations. If the efficiency of such motors is managed properly it can save a considerable amount of energy. The IoT Motor Diagnostic System has a built-in power quality measurement function for electrical signal analysis as an integrated solution that saves energy.

Correctly timed maintenance and repair actions, initiated by the diagnostic system, allows motors to last longer at the lowest cost, without suffering from quality problems or unexpected failures.
