Transient non-linear analysis of a voltage driven reluctance self-oscillating motor

摘要

In this paper a transient analysis of a linear non-switched self-oscillating motor is presented. This kind of electromagnetic device is studied by means of an hybrid Finite Element Method (FEM) Boundary Element Method (BEM) coupled with an external lumped parameter circuit. The magnetic force acting on the moving part of the motor is evaluated using Kelvin's formulae. Several simulations taking into account non-linear properties of the ferromagnetic materials and conductive effects are performed and then compared with experimental results.
