In the field of electric machine design, increasing torque density and efficiency is one of important aims. When machines fail to meet torque density requirements or are simply incapable of matching load torque, gears are commonly used. Gears are used abundantly in industry, because they can change speed and torque according to application requirements. However, mechanical gears have some disadvantages such as acoustic noise, high cost of maintenance, frequently maintenance needed and also low reliability. Consequently, Magnetic Gears (MG) have been proposed as a means of increasing torque density within electromechanical systems, while avoiding problems associated with traditional mechanical gears. Magnetic gears have many advantages in comparison with mechanical gears that will be discussed in following sections. In this thesis, a newly configured magnetic gear will be proposed which has higher torque capability and better efficiency in compared with other magnetic gears. In the first chapter, a brief introduction is given and history of magnetic gear will be explained, also, objectives of using magnetic gears will be discussed. Then background knowledge about gears which can help us to have better understanding about principles of magnetic gears will be presented. In the second chapter, mathematical computation and formulation of flux generation in magnetic gear will be explained. Moreover, equivalent circuit of Magnetically Geared Permanent Magnet Generator (MGPMG) will be explained. In the third chapter, design technics, simulation results of newly configured magnetic gear with new capability and also efficiency analyses will be presented. First of all, analyses which have been done on conventional form are presented. Then, proposed configuration will be introduced, additionally; result of static, steady state and transient analyses will be presented. Lastly, result of efficiency calculations and comparison will be given also in this chapter. In the last chapter, new and recommended ideas which are better to be done in further works is discussed.
