Product Introduction

The Musktool-Fluke MDA 550 Motor-Drive Analyzer saves time and eliminates the hassle of setting up complex measurements, while simplifying motor-drive troubleshooting. 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-550 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-550 is the ideal portable motor-drive analysis test tool 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, voltage modulation, and motor shaft voltage discharges.

  • 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 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.
