Stability Analysis of a Levitated Micro-Motor

Research output: Contribution to journalArticle (Academic Journal)peer-review


Finite element modelling is used to investigate and optimise the radial stiffness of a levitated disc thereby improving its radial stability. The disc is to be used as a bearing for high-speed micro-machines such as micro-motors and micro-turbine generators. Particle Swarm Optimisation is used to find the optimal geometry and excitation which yield the best radial stiffness while maintaining strong and uniform axial support.
