Hybrid excitation is a technology that combines the advantages of field windings and permanent magnets for inducing magnetic flux. This article studies benefits hybrid provides an outlook on their possible applications, such as wind power generators electric vehicle motors. Compared to magnet-based machines, gives variable flux while still using advantage portion also looks into some different ...

Abstract—This paper presents a several diagnostic methods designed to electrical machines especially for permanent magnets (PM) machines. Those machines are commonly used in small wind and water systems and vehicles drives. Those methods are preferred by the author in periodic diagnostic of electrical machines. The special attention should be paid to diagnostic method of turn-to-turn insulation...

While electrical machine designers typically go to great lengths choose the optimal number of stator slots based on electromagnetic performance, often thermal aspects this selection are overlooked. This article investigates multi-domain impacts related slot selection, combining both and aspects. Taking an existing 42-kW 4-pole, 12-slot with Halbach-array surface-PM rotor, used within a more-ele...
