An easier way to troubleshoot

It can be problematic to begin testing as there is usually a lack of, or incomplete, work history for the equipment. This includes documentation of specific tests and measurements performed previously, work completed or the condition of individual components after maintenance.

The new Fluke MDA-550-III Motor Drive Analyzer is designed to make motor drive testing more efficient and insightful with the capability to document the process at each step along the way. These reports can be stored and compared against subsequent tests to get a complete picture of motor drive maintenance history.

Capture and document to isolate motor drive train problem

Getting to the root cause of a motor drive system failure or performing a routine preventive maintenance check is best done with a set of standard tests and measurements at key points within the system.

The Fluke Motor Drive Analyzers guide you through the key tests and automate many of the needed calculations so you can have confidence in the results. Plus, you can save data to a report at any test points for easy documentation.

How to prevent electrical damage on bearings?

Simple setup
Signal display of discharges
Events – number of discharges/sec
Tip: Do periodic checks as bearing lubrication, load and other factors can influence the rate and occurrence of discharge events
Fast voltage discharges across the bearing surfaces can cause fluting or electrical erosion on the bearings. Motor Shaft Voltage is the answer. Measuring a fast turning motor shaft can be troublesome and risky.

The Fluke MDA-550-III shaft voltage probe provides a safe and easy way to make electrical connections to motor shafts. This unique function accounts for the rate of occurrence and amplitude of damage.
