AI Article Synopsis
- The paper discusses a four-pole magnetic bearing designed with permanent magnets, which helps reduce electric energy consumption compared to traditional active magnetic bearings.
- The first section focuses on the bearing's design and its finite-element model, while the second section explains the simulation model used for transient time analysis.
- The simulations calculate how the rotor responds to lifting from its starting position, sudden position changes, and external forces applied along the axis.
Article Abstract
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 -axis.
