“…the free space between the rotor and the stator, can not be as small as that in conventional machines. Otherwise, higher-than-accepted losses will be induced in the rotor, including eddy current losses in the electromagnetic (EM) shield and the cryostat wall [12], [13], and also AC losses in the HTS field winding [14].…”

High-temperature superconducting (HTS) generators are being considered as a competitive candidate in large direct-drive (DD) wind turbines because of their features of being lightweight and compact. Normally a large air gap is inevitable in partially HTS generators, sacrificing the torque producing capability. In this paper, multi-phase armature windings for HTS generators are investigated to reduce the air gap length in HTS generators while not compromising generators' performance. Therefore, the torque density of HTS generators can be improved without any added costs. Five different multi-phase armature winding schemes are studied in the paper. Their performance regarding torque production and rotor losses in a 10 MW DD HTS generator are examined. The findings show that employing multi-phase armature windings can reduce the mechanical air gap without generating extra eddy current losses in the rotor, and the torque production can be improved by up to 9.1%. In addition, the alternating magnetic field reaching the HTS field winding are also reduced by using multi-phase armature windings, resulting in lower AC losses and cooling costs.

“…IMs are widely applied in EVs [1]- [7] because of their simple structure, convenient manufacturing, reliable operation, and low cost. The stator current contains some harmonic components because of the air gap magnetic field distortion, deadtime effect, and the non-linear characteristics of inverters.…”

In order to solve the problem of torque ripple caused by current harmonic of induction motors (IMs) in electric vehicles (EVs) drive system, this paper presents a novel control method in the feedback channel based on morphological filters (MFs) to suppress the current harmonics. First, an analytical model of current harmonics is established, and the current harmonic composition to be filtered in the feedback channel of motor control systems is provided. Second, on the basis of filtering requirements on the feedback channel and the basic idea of mathematical morphology, a hybrid digital MF is designed. The MF is subsequently added on the current loop to suppress the current harmonic components. The shape, width and height of the structural elements of the filter are optimized by parameters comparison methods to improve the performance of the filter in harmonic suppression. Finally, compared with the method based on Butterworth Filter and without filters, simulation and experimental results verify the feasibility and effectiveness of the proposed method for suppressing harmonics.

“…Owing to simple structure and high efficiency, switched reluctance motor is suitable for a lot of industrial applications. Due to low critical speed and increased frictional resistance, traditional mechanical bearing limits further increase of the critical speed of motor [1][2][3][4]. The emergence of magnetic bearing technology overcomes the shortcomings of mechanical bearing [5][6][7][8][9][10].…”

In order to solve the strong coupling problem of a traditional bearingless switched reluctance motor (BSRM), this paper proposes a new type of hybrid excitation double stator BSRM (HEDSBSRM). The new motor can realize self-decoupling between torque and suspension force. In addition, the two degrees of freedom suspension force can also be decoupled. First, the topology of the motor is proposed, and the generation mechanism of suspension force and torque are expounded. Second, the torque winding structure is optimized. The multi-objective sensitivity optimization design method is used to screen out the key structural parameters that have the greatest influence on the average suspension force, average torque, and core loss. Then, the optimal structural parameters are obtained by the control variable method. Finally, based on the optimized motor, the finite element method (FEM) is used to analyze the electromagnetic characteristics including the suspension force, torque, and coupling of the motor. The simulation results verify the correctness of the proposed design method and analysis of motor performance.
