TL;DR: In this article , the shape of polar anisotropic magnetizer with a magnetic flux concentration structure is proposed to reduce the range of the dead zone, and the results were analyzed through finite element analysis and the final model was selected by analyzing the inner and outer teeth thickness of the teeth of the magnetizer as design variables.

TL;DR: In this paper , a method for interpolating inductance among important factors for motor torque control is proposed, and the validity of the proposed flux-torque control is verified based on the actual data obtained from the finite element analysis (FEA) and actual manufactured motor shape.

TL;DR: In this article , a method to reduce the bearing force ripple and torque ripple of an integrated magnetic bearing motor through parameters for a Halbach array and permanent magnet tapering was proposed, and the average bearing force and torque were maximized and the ripple was minimized through the rotor parameters.

TL;DR: In this article , an integrated magnetic bearing structure can be designed that secures the space inside the rotor core as a space for inserting the magnetic bearing, where the bearing magnetic flux for controlling the rotor position is affected by the magnetic field of the permanent magnet and the rotating magnetic force of the phase winding of the stator.

TL;DR: In this article, a 4-layer hybrid winding (concentrated + distributed winding) layout was proposed to make the operating range of the traction motor, which is used for HEV and EV, widening and redesigning the permanent magnet's location.
