The need
In the process of designing a new motor/generator;
Method of Finite Element Analysis is used
The disadvantage - Computing time
Alternate option – Nonlinear Magnetic Analysis on an equivalent magnetic circuit of the whole machine
Because of Magnetic Saturation in Stator teeth, the analysis becomes Nonlinear.
The procedure
The permeance values of the saturable permeance
tips are calculated by referring to the permeability on
The analysis is capable of calculating the flux distribution and Torque characteristics in the presence of magnetic saturation.
