“…There are various simulation models dedicated to transient simulations for magnetic bearings. The straightforward simulation model is based on partial differential equations (PDEs) that describe the motion of the rotor, and the magnetic bearing is simulated as a current-controlled device with two parameters: current and position stiffness [ 11 ]. Additionally, this model can take into account the voltage drop across windings.…”

This paper presents the design of and transient time simulations for a four-pole magnetic bearing with permanent magnets. The usage of permanent magnets reduces the consumption of electric energy in comparison to a traditional active magnetic bearing. Permanent magnets are installed in the yoke of the stator core to limit the cross-coupling of the magnetic flux generated by the windings. The first part of this paper presents the design of the magnetic bearing and its finite-element model, while the second part describes the field-circuit indirectly coupled finite-element model for the transient time simulation. The presented simulation model was used to calculate the transient response for the rotor lifting from the starting position, the step change in the rotor position and the change in the rotor position under an external impact force applied along the y-axis.
