This paper describes an approach to the optimal design of high efficiency permanent magnet reluctance motors (PRM) based on the Taguchi method coupled with finite element analysis (FEA) because of the requirements of the impending IE4 Super Premium Efficiency classification. The objectives of the optimal design are to increase the efficiency and to decrease an amount of the permanent magnet of the...
Hybrid Vehicles (HEVs) and Electric Vehicles (EVs) improve the efficiency of a drive and reduce CO2 emissions by regenerative braking and operating the engine under optimum conditions. It is desirable to decrease the motor size and increase the maximum torque to minimize the driving units. For these purposes, motors employing permanent magnets have been commonly used recently. For HEVs and EVs motors,...
Reduction of electrical consumption of a electric vehicle (EV) and electrical appliance is one of solutions for reduction of CO2 gas. Then, we have developed a novel permanent magnet motor for energy saving. In this paper, we propose a novel motor that can change magnetic flux by a new method magnetizing a permanent magnet and clarify the principle and unique characteristics. Furthermore, the results...
