Abstracts: Electromechanical energy conversion employing generators and motors play a crucial role in energy production and consumption. Permanent magnet technology represents a new enhanced area that can be used both in generators and motors. Electromechanical power conversion based on permanent magnet technology is inevitably when energy efficient solutions for generating and motoring are considered. The rotor of a typical vertical wind turbine rotates at a speed of 20-300 rpm. In conventional wind power plants the generator is coupled to the turbine via a gear so that it can typically rotate at a speed of 1000 or 1500 rpm. The wind power plant can be simplified by eliminating the gear and by using a low-speed generator, the rotor of which rotates at the same speed as the rotor of the turbine. The hypothesis in this work is that the typical generator-gear solution in the wind power plant can be replaced by a low-speed PM synchronous generator. In this report has been put on the design of Permanent Magnet Synchronous Generator (PMSG) suitable for a small scale Vertical Axis Wind Turbine (VAWT). Literature survey on different topologies of electrical machines with focus on PMSG including Permanent Magnet (PM) configurations, different windings is presented. PMSG is designed and the design will be verified by means of Finite Element Method (FEM) analysis using MAXWELL 14.O software.
