The main purpose of this rapport is to design a generator with a high efficiency for a low speed appliance. The process of the design will be clearly described and results and simulations are discussed throughout. Software such as JMAG is used in order to simulate the system and attain values for further calculations. The project results in determined dimensions and a method of heat removal which results in attaining a suitable operation temperature. This generator can also be applied in micro wind and hydrology power plant.
