Optimal Winding Arrangements of a Bearingless Switched Reluctance Motor
IEEE Transactions on Power Electronics, 2008Winding arrangements of a bearingless switched reluctance motor strongly influence the operation state of its power converters so much as the rotation and levitation of the motor. This paper proposes some optimal winding arrangements, which suit for a three-phase half-bridge converter or a three-phase four-leg converter. First, the optimal main winding

New Design of the Bearingless Switched Reluctance Motor
2021 13th International Symposium on Linear Drives for Industry Applications (LDIA), 2021To obtain large levitation force density, a novel four degrees of freedom (4-DOF) bearingless switched reluctance motor (BSRM) with axial torque fluxes is proposed. Furthermore, independent torque magnetic circuit and levitation magnetic circuit designs are adopted to obtain self-decoupling of levitation force and torque.

Optimal design of a bearingless switched reluctance motor
2009 International Conference on Applied Superconductivity and Electromagnetic Devices, 2009This paper presents a method of optimizing number of turns of the main and radial force winding for a bearingless switched reluctance motor (BSRM) with 12/8 teeth configuration based on its mathematical model. The radial force and torque of BSRM are analyzed on condition of different combinations of the magnetomotive force of two kinds of windings. The

Stator Vibration Analysis of Bearingless Switched Reluctance Motors
2010 International Conference on Electrical and Control Engineering, 2010Radial magnetic force acts on the motor stator cause large vibration and acoustic noise, that have limit the application of switched reluctance motors (SRMs). They can be aggravated when there is unbalanced force due to rotor eccentricity. This paper analyzed the function of bearingless technique in compensating the unbalanced magnetic attraction force;

Levitation performance analysis for bearingless switched reluctance motor
2015 18th International Conference on Electrical Machines and Systems (ICEMS), 2015The performance of a bearingless motor is determined by the levitation characteristic. This paper shows the levitation performance analysis of a kind of bearingless switched reluctance motor (BLSRM), which separate the levitation control from the torque control. Firstly, the structure and operation principle of the BLSRM are introduced briefly.
