Here are some tips that you can do to care for heavy equipment:

1 Pay attention to the cleanliness of the oil

In caring for heavy equipment and excavators, the most important thing to pay attention to is to pay attention to the cleanliness of the oil. Dirty oil will make the engine heat quickly and affect the performance of the excavator.

2. Pay attention to oil level

Do not let the oil level be below the standard. It will make the machine work not smoothly and not function properly, such as jamming some parts and even wear and tear of engine components.

3. Air filter

Replace the air filter to maintain the machine so that the incoming air is always clean and not mixed with dust because a dirty air filter will make the diesel tank combustion incomplete.

4. Make sure the fuel is tightly close

Always check the fuel filter cap, so that the results from diesel deposits do not meet the filter. Sometimes this is often overlooked and makes heavy equipment work harder.

Always pay attention to the maintenance of your heavy equipment to reduce the risk of damage at a greater cost and increase the safety of employees.

3-Phase motors use 3 electric currents to provide power to the internal electrical components, such as the stator, rotor, windings and cabling. When a motor has a problem operating, the components must be analyzed to determine the exact location of the issue to be resolved.

Understanding the Basics of 3-Phase Motor Operation
At the heart of a three-phase motor lies the intricate interplay between the stator and rotor components.

The stator, composed of three windings, creates a rotating magnetic field when supplied with three-phase alternating current. This rotating field induces a current in the rotor, which in turn generates its own magnetic field. The interaction between these magnetic fields produces the torque that drives the motor’s rotation.

The speed of a three-phase motor is determined by the frequency of the supply voltage and the number of poles in the motor’s design. By adjusting the frequency, operators can precisely control the motor’s speed, enabling fine-tuned control over industrial processes.

Three-phase motors offer several advantages over their single-phase counterparts, including higher efficiency, greater starting torque, and more balanced power distribution. These characteristics make them the preferred choice for a vast array of industrial applications, from pumps and compressors to conveyor belts and cranes.

3-Phase Motor Fault Finding Steps
Diagnosing and resolving issues with 3-phase motors can be a complex task, but with the right tools and techniques, you can efficiently identify and address the root causes of common faults that lead to motor failure.

Visual Examination
First, carefully examine the physical condition of the motor, its connections, and the surrounding environment, we can often uncover obvious issues that may be contributing to the problem.

Analysis of Internal Electrical Components
If there are no obvious damages or issues with the motor and its cabling, the next step is to use specialized testing equipment to measure parameters such as winding resistance, insulation resistance, and current draw. These measurements will provide valuable insights into the motor’s internal health and help us pinpoint any electrical faults.

Mechanical Analysis
Finally, the third phase of our fault finding process involves dynamic testing, where the motor’s performance is observed under load. By monitoring the motor’s speed, vibration, and other operational parameters, we can identify any mechanical issues that may be impacting its efficiency and reliability.

Electric Motor Analysis Tools & Technologies
When it comes to maintaining and troubleshooting 3-phase motors, having the right tools and knowledge is crucial.

Multimeters
One of the most common instruments used to diagnose motors is a multimeter.

Multimeters allow you to measure crucial electrical parameters such as voltage, current, and resistance across the motor’s windings.

However, the measurements of these parameters often overlook faults that can be found with other instruments that measure impedance, inductance, phase angle and current frequency.

Meghommeters
Another common tool used in motor analysis is the megohmmeter.

A megohmmeter is an electric meter that measures very high resistance values by sending a high voltage signal into the object being tested.

Megohmmeters provide a quick and easy way to determine the condition of the insulation on wire, generators, and motor windings.

However, megohmmeter insulation testing only detects faults to ground. Because only a portion of motor electrical winding failures begin as ground faults, many motor faults will go undetected using this method alone.

Surge Testing
A surge test subjects the system to voltage spikes on top of the nominal voltage input to determine weaknesses in insulation.

Surge testing should be avoided for motor analysis because it can be destructive to the internal windings.

Motor Circuit Analysis (MCA)
Motor Circuit Analysis (MCA) is a non-destructive, deenergized test method to assess the health of a motor.

Initiated from the Motor Control Center (MCC) or directly at the motor itself, this process evaluates the entire electrical portion of the motor system, including the connections and cables between the test point and motor.

Electrical Signature Analysis (ESA)
Electrical Signature Analysis (ESA), which encompasses both Motor Voltage Signature Analysis (MVSA) and Motor Current Signature Analysis (MCSA), is an energized test method where voltage and current waveforms are captured while the motor system is running.

Energized testing provides valuable information for AC induction and DC motors, generators, wound rotor motors, synchronous motors, machine tool motors and more.

Preventive Maintenance to Avoid 3-Phase Motor Failures
Proper preventive maintenance is crucial for avoiding costly 3-phase motor failures. By implementing a proactive approach, you can extend the lifespan of your motors and minimize unplanned downtime.

Condition Monitoring
One of the key steps in preventive maintenance is regular inspections. Closely monitor your 3-phase motors for signs of wear, such as bearing issues, insulation degradation, and imbalances.

Scheduled assessments of rotating machinery with Motor Circuit Analysis should be conducted to monitor conditions over time. Finding and resolving early stage faults before motor failure can be imperative to a business’ production.

Environment
Equally important is maintaining optimal operating conditions. Ensure your motors are not overloaded, properly ventilated, and running at the correct voltage and frequency. Neglecting these factors can significantly contribute to premature motor breakdowns.

Predictive Maintenance
Additionally, implementing a comprehensive predictive maintenance program, including electrical signature analysis, vibration analysis and thermography, provides valuable data to identify potential issues before they arise. This data-driven approach empowers businesses to make informed decisions and schedule maintenance proactively.

Conclusion
Because a motor’s intricate components are shielded within, 3-phase fault finding is a tricky but possible task with the right approach and the right tools.

Don’t let 3-phase motor problems catch you off guard. Invest in the right tools and techniques, and you’ll be able to keep your critical equipment running smoothly for years to come.

Testing At The Motor Junction Box
As with many motors a simple way to test the six lead motor involves going directly to the motor junction box. After confirming that all Lock Out / Tag Out requirements have been complied with and the motor leads have been checked for the presence of voltage, the motor junction box can safely be opened.
If the motor leads from the controller and the internal motor wires are labeled, make note of that connection. If they are not marked then mark them with colored tape or other identification so that they can be properly reconnected when testing is complete. Disconnect the motor leads from the starter from the internal motor wires, or from the terminals in the box.

The internal motor wires or terminals should be numbered, one through six. As a check, you should be able to test for electrical continuity between terminals/wires 1-4, 2-5, and 3-6. These are your phase wires (A, B, C, or 1, 2, 3).

ATIV
To test the motor with an AT IV you can connect the instrument to terminals/wires 1-4 for phase 1, terminals/wires 2-5 for phase 2, and terminals/wires 3-6 for phase 3. All three windings should have the INS/grd test performed individually.

AT33IND or AT5
To test the motor in the WYE configuration you must short together terminals/wires number 4, 5, and 6. The wires can either be bolted together or significantly sized shorting jumpers used.

The tester(s) can then be connected to terminals/wire numbers 1, 2, and 3. Only one INS/grd test is necessary in this configuration.

Testing At The Motor Controller
There are many different ways to test six lead motor from the motor control depending on the size of the cables and the configuration of the control cabinet. In the cabinet pictured below, using an:

ATIV
At the bottom of the RUN and DELTA contactors do a normal test between 1-4, 2-5, and 3-6. Again, each winding should have the INS/grd test done separately.

AT33IND and AT5
The 4, 5, and 6 leads need to be shorted together. This can either be done with jumpers at the bottom of the DELTA or WYE contactors or the WYE contactor can be somehow forced. With this shorting accomplished the instrument can be connected to cables 1, 2, and 3 at the bottom of the RUN contactor.

A di-electric material is a material which is a poor conductor of electricity but an efficient supporter of an electrostatic field. When an electrical insulating material is subjected to an electrostatic field, opposing electric charges in di-electric material form di-poles.Figure of dipoles in dissipation factor.

A capacitor is an electrical device that stores an electrical charge by placing a dielectric material between to conductive plates. The Ground Wall Insulation (GWI) system between the motor windings and the motor frame create a natural capacitor. The traditional method of testing the GWI is to measure the value of the resistance to ground.

This is a very valuable measurement for identifying weaknesses in the insulation but fails to defi ne the overall condition of the entire GWI system.

The Dissipation Factor provides additional information regarding the overall condition of the GWI.

In the simplest form when a dielectric material is subjected to a DC fi eld the diploes in dielectric are displaced and aligned such that the negative end of the dipole is attracted toward the positive plate and the positive end of the dipole is attracted toward the negative plate.

Some of the current that flows from the source to the conductive plates will align the dipoles and create losses in the form of heat and some of the current will leak across the dielectric. These currents are resistive and expend energy, this is resistive current IR. The remainder of the
current is stored on the plates current and will be stored discharged back into system, this current is capacitive current IC.

When subjected to an AC field these dipoles will periodically displace as the polarity of the electrostatic field changes from positive to negative. This displacement of the dipoles creates heat and expends energy.

Simplistically speaking, the currents that displace the dipoles and leaks across the dielectric is resistive IR, the current that is stored to hold the dipoles in alignment is capacitive IC.
Aligned dipole forms from dissipation factor.

Dissipation Factor is the ratio of the resistive current IR to the capacitive current IC, this testing is widely used on electrical equipment such as electric motors, transformers, circuit breakers, generators, and cabling which is used to determine the capacitive properties of the insulation material of the windings and conductors. When the GWI degrades over time it becomes more resistive causing the amount of IR to increase. Contamination of the insulation changes the dielectric constant of the GWI again causing the AC current to become more resistive and less capacitive, this also causes the dissipation factor to increase. The Dissipation Factor of new, clean insulation is usually 3 to 5%, a DF greater than 6% indicates a change in the condition of the equipment’s insulation.

When moisture or contaminants are present in the GWI or even the insulation surrounding the windings, this causes a change in the chemical makeup of the dielectric material used as the equipment’s insulation. These changes result in a change in the DF and capacitance to ground.

An increase in the Dissipation Factor indicates a change in the overall condition of insulation, comparing DF and capacitance to ground helps determine the condition of insulation systems over time. Measuring Dissipation Factor at too high or too low temperature can result in unbalanced results and introduce errors while calculating.

IEEE standard 286-2000 recommends testing at or around ambient temperature of 77 degrees Fahrenheit or 25 degree Celsius.

Electrical Signature Analysis (ESA) is a predictive maintenance (PdM) technology that uses the motor’s supply voltage and operating current to identify existing and developing faults in the entire motor system. These measurements act as transducers and any disruptions in the motor system cause the motor supply current to vary (or modulate). By analyzing these modulations, it is possible to identify the source of these motor system disruptions. Energized motor testing using ESA will provide valuable information for AC induction and DC motors, generators, wound rotor motors, synchronous motors, and machine tool motors used for PdM testing, commissioning, and troubleshooting.

Current and voltage waveforms are collected using the portable, hand-held, battery operated ALL-TEST PRO On-Line II (ATPOL II) ESA instrument, and then via a Fast Fourier analysis, the technician is able to evaluate both the electrical and mechanical condition of the motor system.

Motor system faults (whether related to incoming power, motor electrical or motor mechanical, mechanical coupling or the driven load) all will have unique signatures when using ESA techniques (see Figure 1). Therefore, with information about the motor and motor system, relevant fault frequencies are identified, and the entire system can be evaluated.

Numerous indications of performance are revealed within the time and frequency domains that provide the required information to determine the ‘health’ of the motor and the impact of the delivered load. This permits actually ‘seeing’ the true running speed, motor slip frequency, gear mesh frequency, drive train components, and gear rotational speeds.

Fast Fourier Transforms (FFT) are used to create both a high and low frequency spectra. The peaks in these spectra correspond to the rotational speeds of the different components in the machine. For example, in the case of a fan driven by an electric motor through a belt, the peaks correspond to the motor speed, pole passing frequency, fan speed, and belt speed. If a gear box is used instead of a belt drive, then spectral peaks will appear at the rotational speed of the gears and gear meshing frequencies.

Performing Electrical Signature Analysis
Nameplate data is not required during the data collection process, but automatic analysis can be performed by entering motor nameplate voltage, running speed, rated power and full load current during the analysis process. Common mechanical system faults between the motor and load due to wear and application include belt or direct drive misalignment, belt or insert wear, belt tension issues, and sheave wear. The load can have numerous types of faults depending upon the type of load. The most common are worn parts (i.e. seals), broken components (gears, fan, impeller blades, etc.), and bearings.

The ESA software allows the technician to enter information about the mechanical system (see Figure 2), and then relevant frequencies are automatically calculated (the software provides cursors for locating these frequencies within the spectra). Driven equipment analysis includes belted, geared, and bladed equipment. Please note that mechanical system information is not required for motor electrical and mechanical analysis and is only relevant when there is a need to analyze the mechanical load.

Figure 2. Electrical Signature Analysis software automates the calculations and provides frequency cursors

As an example, let’s look at the low frequency data from a Dust Collector Fan 1 that is driven by a 150-kilowatt, 400-volt, 260-amp, 1485 RPM induction motor (see Figure 3). Notice the Peak labeled BLT – this is the belt frequency, or speed of the belt. There are multiples of the BLT, which are shown in both spectra. The lower spectra show the Line Frequency Peak and that there are sidebands on either side of the Line Frequency that are at the BLT frequency. The fact that belt frequencies are present, especially at 4.3 Amps, is significant. Side bands are evaluated by the fact that they are present. Also, multiples of the belt frequency- therefore, I suspect some issue(s) with this collector. However, the technician that collected this data and performed the initial analysis choose to monitor this machine versus perform further inspection or testing.

Figure 3. This dust collector fan is driven by a 150-kilowatt, 400-volt, 260-amp, 1485 RPM Induction Motor.

A sister machine, Dust Collector Fan 2, was also tested. In Figure 4, notice that the motor load is lower than Fan 1 (194A vs. 220A), yet the BLT peak is at 8.3A; whereas, Fan 1 had a peak of only 4.3A. From this initial test, we cannot conclude that this is a serious problem, but instead this is a warning flag that something is different about this machine compared to the first.

As this data was taken during the Detection Phase of the PdM work process, the next step is to start the Analysis phase. As part of the Analysis phase, the technician made a quick visual inspection of both machines and noted that the belt with Fan 2 has excessive belt movement compared to Fan 1. The next step is to do some additional work which may include taking additional data with ESA or bringing in other instruments as part of the Analysis Phase.

Conclusion
The electric motor makes an excellent transducer when using Electrical Signature Analysis, as you can evaluate incoming power, the electrical and mechanical condition of the motor, and the driven load. When it comes to power quality, controls, stator and rotor condition, air gaps, bearings, alignment, and load, a developing fault can be detected and trended for Predictive Maintenance purposes – but you must fi rst have the right equipment to perform Electrical Signature Analysis.

This application story is part one of a three part series about using ESA for assessing the condition of motor driven mechanical systems.
