Given the fact that operation of electrical machines generates various loss components finally become heat, developing advanced thermal management technologies is essential to control temperature increases and guarantee safe operations. Meanwhile, armature winding can stand larger currents when are equipped with cooling systems, which directly improves torque/power densities. This paper aims pr...

This article presents a new vibration diagnostic method designed to (PM) machines with permanent magnets. Those devices are commonly used in small wind and water systems or vehicles drives. The author’s method is very innovative and unique. Specific structural properties of PM machines are used in this method electromotive force (EMF) generated due to vibrations. There was analysed number of pu...
