The high performance personal computers (PCs) made possible an impressive development in the domain of the electric machines mathematical models. The circuit-field models become more sophisticated and are used more frequently in computing the electric machines characteristics. In the paper a personal point of view concerning the state of the art and the trends in this domain is presented.

This paper is about the thermal diagnosis and control of electric machines or transformer using a Thermal image camera, color sensor, a microcontroller and a PLC. A color sensor is developed which respond to the colors of thermographic images and when overheating or Hot spot occurs it automatically give alarm signal or it can be used to switch off the electric machines or transformer.

axial flux permanent magnet (afpm) machines are attractive candidates for electric vehicles (evs) applications due to their axial compact structure, high efficiency, high power and torque density. this paper presents general design characteristics of afpm machines. moreover, torque density of the machine which is selected as main objective function, is enhanced by using genetic algorithm (ga) a...

Axial flux permanent magnet (AFPM) generators for small-scale wind turbine applications have proven to be a useful design due to their reliability and ease of construction. Their stators have been realized using concentrate coils of enameled copper wires embedded in an epoxy-resin composite mixture. A static setting, opposed to a dynamic machine environment, is utilized to study the steady stat...
