Unlike using the straightedge method or dial indicators the Fluke 830 performs the complicated alignment calculations for you, meaning you’ll have the answers you need to quickly align your machine and get your plant up and running fast.

An enhanced user interface provides easy to understand results that don’t require extensive alignment knowledge and the unique “All-in-One” result screen that shows you both coupling results and feet corrections (vertical and horizontal) in real terms making it easy to take corrective action.

Since machine downtime is costly, test repeatability is critical. The Fluke 830 uses a patented single laser precision alignment system that provides accurate and repeatable measurement results so you can be assured you’re addressing misalignment problems properly.

Other useful features:

• Includes a unique “All-in-One” result screen that shows both coupling results and vertical and horizontal feet corrections, making it easy to take corrective action
• Features a dynamic machine tolerance check that provides continuous evaluation of alignment adjustments so you know when your machine is in the acceptable range
• Offers unique extend mode to handle gross misalignment by virtually increasing laser detector size
• Provides auto save and resume capability to ensure your data is there when you need it

Check Alignment in Three Simple Steps

1: SETUP
Step-by-step input of machine dimensions.

2: MEASURE
Rotate the shaft and receive instant measurement verification.

3: DIAGNOSE
Actual correction numbers are given along with a 4-level color severity scale, indicating whether your machine is misaligned.

Handling Gross Misalignment

When machines are well outside of accepted tolerances it can be difficult to get accurate alignment readings. For these misalignments the 830 uses a unique “Extend” mode allowing for better measurement accuracy by automatically increasing the effective sensor measurement area. Increasing the sensor measurement area virtually allows the Fluke 830 to address gross misalignment quickly without the need to performa an initial rough alignment.

Rotating Machinery

50% of damage to rotating machinery is directly related to misalignment – most customers ignore it and just replace the bearings, seals and cou-plings. Precision alignment can provide up to 65% reduction in seal repairs, up to 50% longer bearing life, and up to 10% reduction in energy waste. The 830 is essentially a kit that simpli-fies precision shaft alignment, as it does not require in-depth shaft alignment education to operate. It employs an intuitive guided user interface that walks the mechanic through the steps and performs complicated alignment calculations for your team. This means you’ll have the answers you need to quickly align most (not just a few) of your machines and get your plant up and running fast.

Simply select a test and the step-by-step guided measurements show you where to make voltage and current connections, while the preset measurement profiles ensure you will capture all the data you need for each critical motor-drive section—from the input to the output, the DC bus, and the motor itself.

From basic to advanced measurements, the MDA-500 Series has you covered, and with a built-in report generator you can quickly and easily generate as-found, and as-left reports with confidence.

The MDA-510 and MDA-550 are the ideal portable motor-drive analysis test tools and can help safely locate and troubleshoot typical problems on inverter type motor-drive systems.

• Measure key motor-drive parameters including voltage, current, DC Bus voltage level and AC ripple, voltage and current unbalance and harmonics (MDA-550), voltage modulation, and motor shaft voltage discharges (MDA-550).
• Perform extended harmonics measurements to identify the effects of low and high order harmonics on your electrical power system.
• Conduct guided measurements for motor-drive input, DC bus, drive output, motor input and shaft measurements (MDA-550) with graphical step-by-step voltage and current connection diagrams.
• Use simplified measurement setup with preset measurement profiles to automatically trigger data collection based on the chosen test procedure.
• Create reports quickly and easily that are perfect for documenting troubleshooting and collaborative work with others.
• Measure additional electrical parameters with full 500 MHz oscilloscope, meter and recording capability for complete range of electrical and electronic measurement on industrial systems.

The Fluke MDA-510 and MDA-550 Motor Drive Analyzers use guided test measurements to make analysis easier than ever.

Drive input

Measure input voltage and current to quickly see whether values are within acceptable limits by comparing the variable frequency drive’s (VFD), also known as a variable speed drive (VSD) or adjustable speed drive (ASD), nominal rated voltage to the actual supplied voltage.

Then, check the input current to determine if the current is within the maximum rating and the conductors are suitably sized. You can also check whether the harmonic distortion is within an acceptable level by visually inspecting the waveform shape or by viewing the harmonics spectrum screen (MDA-550) with total harmonic distortion and individual harmonics.

Voltage and current unbalance

Check the voltage unbalance at the input terminals of the frequency speed drive so you can ensure the phase unbalance is not too high (> 6-8 %), and that the phase rotation is correct.

You can also check the current unbalance, as excessive unbalance may indicate a drive rectifier problem.

Extended harmonic measurements

Excessive harmonics are not just a threat to your rotating machines but also to other equipment connected to the electrical power system. The MDA-550 provides the ability to discover the harmonics of the motor-drive but can also discover the possible effects of inverter switching electronics.

The MDA-550 has three harmonic ranges, 1st to 51st Harmonics, 1 to 9 kHz and 9 kHz to 150 kHz giving the ability to detect any harmonic pollution problems.

DC bus

In a motor-drive the conversion of AC to DC inside the drive is critical, having the correct voltage and adequate smoothing with low ripple is required for the best drive performance. High ripple voltage may be an indicator of failed capacitors or incorrect sizing of the connected motor.

The record function of the MDA-500 Series can be used to check DC bus performance dynamically in the operating mode while a load is applied.

Drive output

Check the output of the inverter drive focusing both on voltage to frequency ratio (V/F), and voltage modulation. When high V/F ratio measurements are experienced, the motor may overheat. With low V/F ratios, the connected motor may not be able to provide the required torque at the load to sufficiently run the intended process.

Voltage modulation

Measurements of the Pulse Width Modulated signal are used to check for high voltage peaks which can damage motor winding insulation. The rise time or steepness of impulses is indicated by the dV/dt reading (rate of voltage change over time), this should be compared to the motor’s specified insulation.

The measurements can also be used to measure switching frequency to identify whether there is a potential issue with electronic switching, or with grounding, where the signal floats up and down.

Motor input

Ensuring that voltage is being supplied at the motor input terminals is key, and the selection of cabling from drive to the motor is critical. Incorrect cabling selection can result in both drive and motor damage due to excessive reflected voltage peaks.

Checking that the current present at the terminals is within the motor rating is important as over current condition could cause the motor to run hot, decreasing the life of the stator insulation which can result in the early failure of the motor.

Motor shaft voltage

Voltage pulses from a variable frequency drive can couple from a motor’s stator to its rotor, causing a voltage to appear on the rotor shaft. When this rotor shaft voltage exceeds the insulating capacity of the bearing grease, flashover currents (sparking) can occur, causing pitting and fluting of the motor bearing race, damage that can cause a motor to fail prematurely.

The MDA-550 Series analyzers are supplied with carbon fiber brush probe tips that can easily detect the presence of destructive flashover currents, while the impulse amplitude and count of events will enable you to take action before failure occurs.

The addition of this accessory and capability of the MDA-550 allows you to discover potential damage without investing in expensive permanently installed solutions.

Step-by-step guided measurements ensure you have the data you need, when you need it
