Summary on Grant Application Form |

This research will investigate the concept of parallel-airgap serial-flux magnetic bearings which develop their bearing forces as a result of the magnetic shear stress acting at each one of a number of airgaps. There is no theoretical maximum to how much static force can be produced between two components by a magnetic field in a given volume. The practical limitations have to do with mechanical constraints such as stiffness strength and dimensional stability of the thin layers of material acting to bend lines of magnetic flux as they pass through. This research will probe the engineering of such bearings by attempting to achieve balanced magnetic and mechanical designs in order to approach the practical limits.Since all rotating electrical machines effectively develop torque as a result of magnetic shear strees in the airgap, the present research will draw heavily on established methods for the design of high torque-density machines (high output coefficient) and transpose as much as possible into the design of parallel-airgap serial-flux magnetic bearings. Mechanical analysis of the dynamics and stability of the thin layers will complement the magnetic analysis of the fields to arrive at near optimal geometries and parameters for high load capacity. Prototypes will be designed, built and tested.
