IET Electric Power Applications, Volume 15, Issue 4, Page 441-452, April 2021., 2021 Abstract In this work, the electromagnetic torque and the unbalanced magnetic force (UMF) in eccentric consequent pole PM (CPPM) machines are investigated. For this investigation, in the first part of the paper, an exact analytical model is provided for the CPPM machine by solving the Poisson equation in the eccentric and salient air gap.

Control System Design for 16/6/8 Double‐Stator Bearingless Switched Reluctance Motor
Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 The 16/6/8 double‐stator bearingless switched reluctance motor (DSBSRM) is used as the object of study in this paper. To solve the problem of torque and levitation force ripples in this motor, a control system direct force control (DFC) and direct instantaneous torque control (DITC) based on the torque sharing function (TSF) are proposed.

Design of novel bearingless switched reluctance motor
IET Electric Power Applications, 2012 This study presents a novel bearingless switched reluctance motor (SRM) with decoupled torque and suspending stator poles. Different from the conventional bearingless SRM, the suspending poles of the proposed bearingless SRM are separated from the phase torque poles.
