The use of wind turbines is increasing at very high rates in many countries around the world. Studies to evaluate the impact of connecting these new generation units to the existing power systems must be done. This paper proposes a wind energy conversion system for a grid connected permanent magnet synchronous generator (PMSG) and power electronic converter system. The model includes a PMSG mod...

In this paper a description and operating principles of a consequent-pole permanent-magnet machine are presented. In addition, a sizing analysis, finite-element analysis, and experimental results for a prototype machine are addressed. Due to its particular configuration, this machine allows for a wide range of control of the air-gap flux with minimum field ampere-turn requirements and without b...

There is a market for small, efficient and costeffective wind generators for mini-grid and remote power systems. Direct-drive permanent magnet generators have become very attractive for this application. This paper describes the improvements achieved in an outer-rotor direct-drive permanent magnet generator by using finite element analysis and optimisation techniques. The starting torque of the...

Abstract—This paper investigates the thermal issue of permanent magnet synchronous generator which is frequently used in direct drive gearless small-scale wind turbine applications. Permanent Magnet Synchronous Generator (PMSG) is designed with 2.5 kW continuous and 6 kW peak power. Then considering generator geometry, mechanical design of wind turbine is performed. Thermal analysis and optimiz...

This paper presents the design optimization of axial flux surface mounted Permanent Magnet Brushless DC motor based on genetic algorithm for an electrical vehicle application. The rating of the motor calculated form vehicle dynamics is 250 W, 150 rpm. The axial flux surface mounted Permanent Magnet Brushless DC (PMBLDC) motor was designed to fit in the rim of the wheel. There are several design...
