This paper introduces a five-axis active-controlled axial-flux self-bearing motor that uses unipolar and four-pole magnetic fields to control radial force tilt moment of the two-pole permanent magnet rotor. The proposed method controls only one-axis by unit rotor stator, therefore two units are necessary for motion control. stators can be placed on double-side single-side In this paper, princip...

The discovery of the superconductivity phenomenon and understanding of electromagnetic properties of high temperature superconducting (HTS) materials allow the optimization and creation of several applications, such as, electrical machines and drives, fault current applications, or superconducting magnetic energy storage, well described in the literature. Electromechanical conversion devices ba...

the direct torque control (dtc) of interior permanent magnet synchronous motor (ipmsm) offers simple structure and fast torque response. the conventional switching table-based dtc (st-dtc) presents some disadvantages like high torque and flux ripple and also variable switching frequency. this paper investigates the improved st-dtc strategies to reduce both torque and flux ripple in dtc of ipmsm...

In this study, the effects of ratio a motor’s axial length to its pole pitch on efficiency, magnetic flux density distribution, torque, torque/weight, and motor volume were investigated in an outer-rotor (hub) brushless direct current motor. The weight electrical machine affects output power, efficiency it is advantageous design electric at appropriate power high with volume. Therefore, aim stu...

This paper presentsan investigation of a 3D-magnetic flux permanent magnet synchronous motor (3D-MF PMSM) used for electric vehicle applications. The investigated 3D-MF PMSM consists an integrated radial-flux and axial-flux structure. It has two air-gaps air-gaps, as well toroidal winding wound stator. structure helps to concentrate all the within maximize torque production. Moreover, there are...
