Cogging Torque Computation and Mesh for Non-radial Electrical Motors in Flux®

Download PDF

All electrical motor designers know that the computation of cogging torque is a tricky task, particularly in 3D. Indeed, the amplitude of this variable is almost the same as numerical noise. In most cases, conventional mesh methodology is not sufficient and specific methodology must be used. At CEDRAT, thanks to its experience, the application team has developed methodologies to successfully compute
cogging torque in most cases. This article presents a specific mesh methodology to compute cogging torque for 3D non-radial electrical motors.
