This study presents design, analysis and real time dynamic torque control of a single-rotor and single-stator axial flux (AF) eddy current brake (ECB). Design of the AF-ECB is accomplished based on magnetic equivalent circuit (MEC) modelling. Influence of the key design parameters on braking torque including permeability and resistivity of the disc material is also investigated. Braking torque profile...
This work presents the design and control of an 8-slot radial flux magnetic bearing. Design of magnetic bearing is carried out with coupled magnetic equivalent circuit model and finite element analysis (FEA). The magnetic design is verified with 2D FEA and good agreement between the two is obtained. Designed magnetic bearing is assembled into a system and fuzzy logic control is applied to the magnetic...
This study is about minimization of cogging torque in an axial flux permanent magnet (AFPM) motor with integer number of slots per pole per phase with the focus on pole shifting or grouping. The analyses of cogging torque component are presented and compared with other cogging torque minimization methods and a reference AFPM motor with standard fan-shaped magnets. It is shown that magnet grouping...
