Why the more traditional methods are not anymore enough

The traditional methods of calculating electrical machines and the intensive use of prototypes to proceed with “trial and error” methods, do not allow to get to the end of a design process with sufficient details to understand the most important problems of the device.

The importance of
dedicated support

FLUX© is supported by a team of experts working in Spin Magnetic Applications: for each type of electromechanical device, we have a dedicated group that is able to follow you throughout your product design with FLUX.

How to get the best with advanced instruments
