Electronic Motor Diagnostics

From Flir Systems Incorporated
 

 
This paper will review electric motor diagnostic applications, including motor circuit analysis and motor current signature analysis. In particular, the paper will focus on how the data is used, what capabilities are available, and how the technologies work with infrared analysis. Several case studies showing how these technologies work together will be included. Electric motor diagnostics (EMD) is a term for test methods and instruments designed for electric motor electrical and mechanical non-destructive analysis. These instruments are used for all motor system related analysis from the generator and prime mover, through the transmission and distribution system, to the electric motor and driven load. These technologies, for the purpose of this paper, will include motor circuit analysis (MCA), a de-energized test method; and electrical signature analysis (ESA), a more advanced method of motor current signature analysis (MCSA). One of the more complex systems to test is the AC salient pole alternator, which we will refer to as a generator for the purposes of this paper.
