[show abstract] [hide abstract]
ABSTRACT: The multiphase Halbach array permanent-magnet machines are very good candidates for special applications such as marine and military applications due to the fault tolerance capability, high output torque, and high acceleration features. In this paper, an optimal design of a five-phase Halbach permanent-magnet machine for high efficiency, high torque, and high acceleration is investigated. A Genetic Algorithm method is used to optimize the design variables based on the analytical model of the motor, which is dependent only on motor geometrical and materials data. In this method, first the main machine design objectives such as efficiency, acceleration, and output power are optimized separately and then a multiobjective optimization considering all objectives simultaneously is given. The detailed finite-element analysis results are carried out to evaluate and verify the performance of the designed machine.IEEE Transactions on Magnetics 07/2011; · 1.36 Impact Factor -
Conference Proceeding: Design and Dynamic Simulation of Five Phase Interior Permanent Magnet Machine for Series Hybrid Electric Vehicles
[show abstract] [hide abstract]
ABSTRACT: Dynamic behavior analysis of electric motors are required in order to accurately evaluate the performance, energy consumption and pollution level of hybrid electric vehicles. Due to high torque to inertia ratio, high reliability, high efficiency and power density, five phase interior permanent magnet machines (IPMs) are good candidate for hybrid electric vehicles. In this paper dynamic performance of a five phase IPM machine for series hybrid electric vehicles application is discussed. For this purpose a high torque density five phase IPM machine with low torque pulsation is designed. The mathematical model of the proposed IPM motor is given. A vector control strategy based on the space vector pulse width modulation (SVPWM) technique is provided to control the machine over a wide speed range. Finally the system is simulated for different operating modes of a typical drive cycle. Extensive simulation results show the accurate performance of the proposed machine.Green Technologies Conference, 2010 IEEE; 05/2010
