9 Oct 2017 Introduction to Electric Motor. System Diagnostics. • The reliability and energy consumption of electric motors and the systems they drive has a direct financial impact to industrial and commercial enterprises. • We will discuss the financial justification for a motor testing program, a general discussion of
Abstract- Amongst many types of electrical motors, induction motors still enjoy the same popularity as they did a century ago. Several factors which include robustness, low cost and low maintenance have made them popular for industrial applications when compared to dc and other ac motors. Another aspect in induction

david.mcfate@iotech.com. Induction Motor Testing and Evaluation. Summary. As energy costs rise, more emphasis is being placed on determining the health of large inductive motors. Motor Current Monitoring and Analysis (MCSA) is a straight forward tool to diagnosing problems with large inductive motors. This technique
If the motor is more than 5 HP, it is usually serviced. Troubleshooting three-phase motors. The extent of troubleshooting a. 3o motor is dependent upon the motor's application. If the motor is used in an application that is critical to the operation or pro- duction, testing is usually limited to checking the voltage at the motor.
All types. • Check the appearance of the motor. Check for body damage or damage to the cooling fan blade or shaft. • Manually rotate the shaft to check the bearing condition. Check for free & smooth rotation. • Note the motor data from the motor NAME PLATE . • Earth Continuity: Use your ohmmeter to verify the resistance

Reverse side of card (at right) is used to record the test data. Figure 3–Typical scale on the Megger insulation tester. HoW To InTERPRET RESISTAnCE REAdInGS. As previously mentioned, insulation resistance readings should be considered relative. They can be quite different for one motor or machine tested three.
Static or insulation testing: is performed with the motor disconnected from the power supply. It is typically performed from the motor control cabinet, and should be carried out in a specific test sequence: Winding resistance test: will highlight dead shorts, loose connections and open circuits. Such tests must be performed.
