Fluke MDA-550 Motor Drive Analyzer Makes Analysis Easier Than Ever with Guided Test Measurements
Drive Input
By measuring the input voltage and current, and then comparing the nominal voltage rating of the drive to the actual voltage supplied, it is possible to quickly see if the values are within acceptable limits. Then, check the input current to determine if the current is within the maximum rating and if the wire gauge is appropriate. You can also check to see if the harmonic distortion is within acceptable levels by visually inspecting the waveform shape or by viewing the Harmonic Spectrum screen, which displays both total harmonic distortion and individual harmonics.
Voltage and current imbalance
Check the voltage imbalance on the input terminals to ensure that the phase imbalance is not too high (>6-8%) and that the phase rotation is correct. You can also check for current imbalance, as excessive imbalance may indicate a problem with the drive rectifier.
Extended Harmonic Measurement
Excessive harmonics are not only a threat to the safety of rotating machines, but also to other equipment connected to the electrical system. the MDA-550 is able to detect harmonics in motor drives, but also the possible effects of inverter switching electronics. the MDA-550 has three harmonic ranges, from the 1st to the 51st harmonic, from 1 to 9 kHz, and from 9 kHz to 150 kHz, and is able to detect any harmonic contamination problem.

DC Bus
In a motor drive, the AC-DC conversion within the drive is critical, and for optimum drive performance it is essential that the voltage is correct, adequately filtered, and that ripple levels are kept low. High ripple voltages indicate a faulty capacitor or incorrect specification of the connected motor. The logging function can be used to dynamically check the performance of the DC bus in load-on operating mode.
drive output
When checking the drive output, focus on measuring the voltage-to-frequency (V/F) ratio and voltage modulation. When the V/F ratio measures high, the motor may be overheating. When the V/F ratio is low, the connected motor may not be able to provide the required torque on the load and thus not be able to adequately run the intended process.
voltage modulation
The measured value of the pulse width modulation signal is used to check for high voltage spikes that may cause damage to the insulation of the motor windings. The rise time or steepness of the pulse is indicated by the dV/dt reading (rate of change of voltage over time), which should be compared to the specified insulation value of the motor. These measurements can also be used to determine the switching frequency to determine if there is a potential problem with the electronic switching or grounding when the signal goes up and down.
Motor Input
Ensuring access to voltage for the motor input terminals is critical, as is proper selection of wiring between the drive and motor. Incorrect wiring choices can result in damage to the drive and motor due to excessive voltage spikes. It is important to check that the current at the terminals is within the motor's ratings, as high currents can cause the motor to overheat and therefore shorten the life of the stator insulation, leading to premature motor failure.
Motor shaft voltage
Voltage pulses from the variable speed drive may couple from the motor stator to the rotor, resulting in voltage across the rotor shaft. When this rotor shaft voltage exceeds the insulating capacity of the bearing grease, flashover currents (sparks) can occur, resulting in pitting and grooving of the motor's bearing races, which can lead to premature failure of the motor. the MDA-550 comes with a carbon fiber brush probe that easily detects the presence of damaging flashover currents, and pulse amplitude measurement and event counting features that allow you to take action before a failure occurs. faults before they occur. Adding this accessory allows you to detect potential damage without having to invest in an expensive, permanently installed solution.
Step-by-step guided measurements ensure you have the data you need when you need it.
The MDA-550 is designed to help you quickly and easily detect and troubleshoot a wide range of common problems with three-phase and single-phase motor inverter drive systems. With on-screen information and a step-by-step setup wizard, you can easily configure the analyzer and get the drive measurements you need to make better maintenance decisions quickly. From power inputs to installed motors, the measurements provided by the MDA-550 allow you to troubleshoot motor drives as quickly as possible.
