Keep your motor-testing options open
This paper presents current methods of electrical test and trend analysis of the operational health of electric motors in the context of successful predictive maintenance programs.
The benefits and features of these various types of test equipment and motor testing methodologies are conveyed in the context of motor/machine systems, which accounts for conditions that can impact the health of a motor but can be external to the motor itself. This paper outlines the concepts of static motor testing, or testing on a motor that is not running, as well as dynamic motor monitoring, which involves performing analysis on motors while they are in service, or operating within their application environment. It also covers an emerging type of online dynamic monitoring involving a permanently-installed networked motor analyzer that enables maintenance professionals to monitor motor system conditions from any Web-accessible computer.
