CALCULATION OF PULSATING LOSSES IN THE AIR‐GAP OF SYNCHRONOUS RELUCTANCE MOTOR USING FINITE ELEMENT METHOD

This paper presents the calculation of pulsating losses in the air‐gap at laminated stator and rotor pole surface of the synchronous reluctance motor (SRM). The calculation is based on change of magnetic flux density in the air‐gap due to the permeance variation on both stator and rotor inner surfaces. These changes are calculated using finite element method. The equation for calculation of the pulsating losses is carried out using reduced Helmholtz's differential equation and the 1st Maxwell equation. Finally, the values measured and calculated are compared to each other.
