Is It Possible to Check if Your Motors are Defect Free?

YES, it’s possible to check if the windings, insulation, rotor, stator, power supply, and connectors are free of defects.

MAYBE, THEY SHOULD HAVE.

A study conducted in 1985 by the Electric Power Research Institute (EPRI) in association with GE found that motors failed 41% due to bearings failures, but 47% of the time due to rotor and stator failures.

1985 EPRI/GE Study EL 4263-286 Volume 1 Project 17

You Don’t Have to be Part of the Statistics

Motor Circuit Analysis (MCA) test the motor when it is off-line, thus making it Safe and a Convenient method to test you motor’s health. Motor Circuit Analysis (MCA) is a de-engergised test method to access the health of the motors in your plant.

This method can be initiated from the Motor Control Centre (MCC) or directly at the motor, itself. The advantages of testing from the Motor Control Centre (MCC) is that the entire electrical portion of the motor system, including the Connections and Cables between the test point and the motor is evaluated.

How Does It Work

The electrical portion of the 3 phase motor system is made up of the basic motor circuit, which is nothing more than 3 simple RCl circuits (resistive, capacitive, inductive). Each basic circuit represents one phase of the three-phase motor system. Each phase of the motor system is identical, each basic circuit should respond the same way to an applied signal.

Diagnostic with regards to failures can start as indicated in the below image, between turns in the same coil, between coils in the same phase, and phase to phase. Motor Circuit Analysis provides a Complete view of the motor in just minutes.

Typical Test Sequence

Traditional Megohmmeter – IS NOT ENOUGH

Megohmmeter insulation testing will only detect faults to ground. Only a portion of the Motor electrical winding failure begin as ground faults, they will go undetected using this method, alone. Moreover surge testing requires the application of high voltages, which can be destructive when testing a motor, making it unsuitable for troubleshooting and true Predictive Maintenance Testing.

Megohmmeter Vs. Digital Multimeter

Therefore,  when  testing  Three-phase  equipment  such  as  motorsgenerators,  or  transformers,  the  response  of  each  phase  is  compared  to  the  other  two.

Phase  resistance  is  evaluated  to  determine  connection  issues;  Inductance  is  evaluated  for  possible  rotor  problems;  Impedance  and  inductance  matching  are  used  to  detect  contamination  or  over-heating  of  the  windings;  Insulation  to  ground  tests  detect  conductor  to  ground  issues

Motor Circuit Analysis Is the Way Forward

Apllications

Industrial IoT for Motor Analysis (Mechanical & Electrical)

MCMMotors drive the industry and provide convenience in our everyday life. These motors are used in various areas of industry all over the world. However, if motors are not maintained properly they can fail. Failure will interrupt production, productivity, affect revenue, energy efficiency, product quality and could result in safety hazards. This invariably could influence increases in cost.

The Internet of Things (IoT) Motor Diagnosis System accurately diagnose the state of equipment in real time and automatically notifies you of the problem and solution.

The IoT Motor Diagnosis System analyzes the voltage and current signal supplied to the motor. To do this you only need to connect a sensor between the motor and the motor distribution board. The diagnosis system analyses the current state of the motor and makes estimations of the motor health. The system runs a comparison analysis between the measured data from the motor and that of the line motor database. It picks up on even the slightest difference and analyses it carefully to diagnose the abnormalities. The system then gives a dense notice of the possible failure in real time.

The system has a periodic notification function which evaluates the performance of the motor and periodically informs you of possible maintenance risks and estimated time to replace parts. The system is installed in the Motor Control Panel and the diagnostic results are analyzed automatically. The IoT Motor Diagnosis System is easy to use even if you’re not an expert. It can conveniently be managed remotely over a network as well.

The IoT Motor Diagnosis System detects both electrical faults and mechanical faults of various types of industrial equipment, driven by a three-phase AC electric motor. Additionally, the system is also capable of detecting abnormalities of the connecting cable and terminal blocks, changes in the load and supply. Hence the system allows you to see in real time whether the motor is performing at its optimum.

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 consumption which could impact on electricity use.

The IoT Motor Diagnosis System has a built-in high-performance power quality measurement function for electrical signal analysis. It is an integrated solution that saves energy.

Correctly timed maintenance and repair actions, initiated by the diagnosis system allows a motor to last longer at the lowest cost without suffering from quality problems, accidents or sudden motor failures.

If you take advantage of the IoT Motor Diagnosis System you can experience a more efficient and safer plant environment with a smaller impact on your maintenance budget.

Watch how easy it is to implement the IoT Motor Diagnosis System!
