Abstract :
[en] The sliding-surface and moving-band techniques are introduced in frequency-domain finite element formulations to model the solid-body motion of the rotors in an cylindrical machine. Both techniques are compared concerning their feasibility and computational efficiency. A frequency-domain model of a capacitor motor is equipped with a sliding surface and compared to a transient model with moving band. This example illustrates the advantages of frequency-domain simulation over transient simulation for the simulation of steady-state working conditions of electrical machines.
