Simulation Drives Electric Machine Design via Advanced Numerical Methods - Article

The design of electrical machines for use in electric and hybrid electric vehicles (EV/HEV) is very much dependent on fl uctuation of cost of materials due to market pressures. Electric machines that use interior permanent magnets rely on rare earth metals that can vary drastically in price over a relatively short period of time. This unpredictability forces design engineers to look at alternative machine designs, such as three-phase induction motors, which are susceptible to fl uctuation in the price of copper.
