Technology for measuring magnetic properties under stress using piezoelectric device
Fujitsu Laboratories today announced the development of technology for measuring the magnetic properties of materials when force (stress) is applied. This will be vital to enabling more advanced large-scale simulations of the kinds of magnetic fields found in the motors of electric vehicles (EV). EV engines, which have numerous operating conditions, such as their rotational speed, need to be prototyped and tested repeatedly under these different conditions. Computer simulations could help make the design process more efficient and increase motor performance, but the simulations need to be able to accurately model energy losses arising from the magnetic fields of different materials, which can change considerably when stress is applied. This creates a need for a technology that can accurately measure the effects of stress.
