Industrial maintenance professionals have used electrical motor test equipment for decades. SKF Electric Motor Condition Monitoring (EMCM) delivers some of the most innovative, cost-effective solutions to help organiza- tions around the world manage the condition of the electric motors and machinery they depend upon. Why motors often fail prematurely Proven static-state and dynamic-state Degraded insulation and worn or failed bearings are the motor test solutions from SKF leading causes of motor failure. There are two main types of SKF electrical motor test equipment enables detection of insulation in a motor: winding (also known as turn-to-turn) developing electric motor problems that vibration-only insulation, and ground-wall insulation. condition monitoring tools do not reveal. SKF static motor Dielectric strength of insulation is the ability to protect one testing analyzers perform tests on motors while in a static, or electrified wire from arcing to another wire, or to ground powered-down state.
