Electric Motor Analysis Course (2-day)
Electric Motor Analysis Course (2-day). The course presents in detail the non-destructive diagnostic methods of electric rotating machines, from the examination of mechanical vibrations to the analysis of electrical parameters with modern tools. It individually examines the most common mechanical and electrical faults of asynchronous, synchronous, and DC motors. During the practical demonstrations, participants receive assistance in handling the tools necessary for investigating electrical phenomena and in mastering professional techniques.
