Variation of direct and quadrature axis inductances of single-sided linear reluctance motor

The paper describes the variation of the direct and quadrature axis inductance, the moving force and power factor of a single-sided linear reluctance motor (LRM) in dependency on different combination of direct and quadrature axis excitation. The magnetic conditions in the motor were analysed by the finite element method. The moving force was calculated by the virtual work method. Calculation results of moving forces at constant direct axis current components show a linear response of moving force in dependency on quadrature axis current component.
