Core loss testing has become essential in ensuring quality electric motor and generator repairs. The stator lamination is tested to determine the watts loss per pound of steel magnetic core iron. When electric motor & generator windings fail, they often damage the stator lamination. This causes hot spots to develop leading to premature winding failures. If your company has had an electric motor or generator repaired only to have the machine run hot and burn up after a short operating time, the most likely cause was a damaged stator lamination core. This problem will no longer be a cause of concern when this test is performed.
