Advanced permanent magnet machine design and construction for wind power generation and traction applications

The paper presents the optimization procedure of permanent magnet electrical machines, presenting important advantages in wind power generation and traction applications. Both "Internal" low remanence permanent magnet and "Peripheral" Neodymium alloy magnet rotor structures have been considered and compared. Design optimization has been performed based on the finite element method and sensitivity analysis techniques. The developed methodology precision has been checked through measurements on a 2 kW electrical machine prototype and the good agreement with the experimental results illustrates the method suitability for permanent magnet machine design.
