By DAKYO Brayima; AZZOUZI Jaouad; BARAKAT Georges [View]
[Download]

Abstract: This paper presents a multiobjective optimization of the design of a 10 kW / 130 rpm axial flux permanent magnet synchronous generator (AFPMSG) dedicated to wind energy application. Firstly, a coupled electromagnetic, thermal and mechanical models used in the design procedure of the AFPMSG are presented. Secondly, the developed genetic algorithm (GA) approach is presented in three parts: the basic principles of the GAs, the constrained to the unconstrained optimization conversion and the multiobjective optimization method. Thirdly, an analysis of the multiobjective optimization method robustness is performed and applied in the case of 10 kW / 130 rpm AFPMSG. According to the obtained results, the presented GA approach is a fast and an efficient technique to solve the resolution of the design multi objective optimization problems.

   Design Optimization of Interior Permanent Magnet (IPM) Motors With Maximized Torque Output in the Entire Speed Range
By ZARKO Damir; LIPO Thomas A.; BAN Drago [View]
[Download]

Abstract: A multiobjective optimization procedure for the design of interior PM motors based on Differential Evolution algorithm is presented. A comparative analysis has been carried out for the optimized 5 kW, 50 kW and 200 kW IPM motors with two and three layers of cavities in the rotor to show design trade-offs between goals to minimize the motor volume while maximizing the power output in the field weakening regime with the back emf constraint as the main limiting factor in the design. The finite element method has been used to calculate the motor parameters during the optimization process. The effectiveness of the proposed design methodology has been shown on a 1.65 kW IPM motor with two layers of cavities in the rotor for which a prototype has been built and tested.

   Initial Rotor Position Estimation of Half-Wave Rectified Brushless Synchronous Motor
By HIGUCHI Tsuyoshi; ABE Takashi; OYAMA Jun [View]
[Download]

Abstract: The goal of this research is to realize a complete position and speed sensorless system using a "Half -Wave Rectified Brushless Synchronous Motor" we proposed as a novel AC servo motor. This paper proposes an initial rotor position estimation method using the bias frequency component of a Half-Wave Rectified Brushless Excitation. This technique is verified by simulations and experiments.
