Analytical computation method of transverse flux permanent magnet excited machines via nodal analysis

This paper is about an analytical computation method for a transverse flux permanent magnet excited machine. The analytical computation method makes use of a magnetic equivalent circuit with lumped elements considering saturation. The magnetic values of the magnetic equivalent circuit are solved via nodal analysis. Having the entire magnetic equivalent circuit of one pole pair of the transverse flux permanent magnet excited machine electromagnetically solved, the resulting torque can be computed by applying virtual displacement. The calculation is based on the derivation of the air gap´s permeance. Although the analytical calculation method includes the calculation for all positions of the rotor with different currents, it merely lasts few seconds. These results will be compared with the results of a finite element analysis simulation.
