N2 - In this paper the rotor geometry of a DC-biased Vernier Reluctance Machine (VerRM) operated in DC-biased modes is optimised to minimise noise and vibration. A baseline case is used and then optimised considering both shaping and windows structures. This is evaluated for its electromagnetic and mechanical characteristics and vibration behaviour, using the Largest Force Harmonic (LFH) as a proxy. A Design of Experiments (DoE) is then performed to identify the contribution of geometrical parameters to the LFH, torque and torque ripple produced. Optimisation is performed via ANSYS to determine the optimal geometry values for DC-biased VerRM. The optimum conditions are then extensively investigated in the torque, force and vibration domains to identify the contributions.
