Electrical Rotating Machine Stator Core Design Characteristics, Failure and Testing
Learn how to evaluate stator core conditions by learning its characteristics, failure modes and diagnostic techniques.
These 2 half-days Online Virtual instructor-led Training (VILT) waste no time but focus directly on the overview of the stator core design, different components, construction and characteristics. This will follow by the theoretical explanation and representation of the stator core current flows. Description of the different stator core’s failure modes with explanation and representation of the failure process. Aspects considered will include : Back of core burning, Burning at core bars, Surface anomalies, Damage at core ends, Effects of leakage flux and flux fringing, Catastrophic failure at core clamping and tooth supports and Overheating will also be discuss.Excitation circuit design, Core Testing Types & Comparison: The second session, attendees will learn how to evaluate and design the excitation circuit. Required for the stator core tests. The instructor will show the types of core testing which is available to determine the condition of the stator core on big rotating machines which are:
- Power Flux Test (The test is more expensive compared to the ELCID test, but the diagnostic data collection and interpretation is easier) and
- Electromagnetic Core Imperfection detection (EL CID test) Test (which do not require external power source and no risk of damaging the stator core).
The instructor will further explain the testing principle, excitation requirement, measuring techniques and data interpretation. For each core testing types, advantages and disadvantages will be described during the explanation and comparisons are conducted in the case studies.
