The focus of this work consists in analyzing water flow inside a water cooling electric motor frame. Aiming of work is in the comparison of load losses and the avoidance of hot spots in two types water cooled frames. Total losses of electrical machine were considered as thermal load. Electrical motor is new designed electrically excited synchronous machine for automotive industry. For the development of this work computational fluid dynamics (CFD) was used.

The paper discuses an important construction aspects of resonant wireless power transfer (WPT) system for small portable devices. It focuses mainly on key electrical parameters of the systems resonant linkage and its proper construction shape. All presented theoretical presumptions are consequently verified by detailed measurement.

The paper deals with a study of new synchronous machine for use in hybrid vehicle. The synchronous machine is projected as permanent magnet synchronous motor with outer rotor embedded into rear rim of a bus. The main target of the study is design of an air self-cooled hub-wheel PMSM from electromagnetic point of view and using finite element analysis of electromagnetic field and thermal distribution. The analysis of losses in permanent magnets is also mentioned.

The paper deals with design of an electrically excited automotive synchronous motor and follow-up finite element method analyses. The machine is designed for water cooling of outer cover and enclosed inner air cooling circuit. The paper deals with complete design and analyses of the machine - calculation of losses, ventilation and cooling conditions.
