“…PMSGs are commonly used in various industrial applications such as wind turbines, 10,11 hydraulic power generation systems, 12 and electric vehicles. 13,14 In spite of all their advantages, one of the biggest disadvantages of permanent magnet machines is the occurrence of cogging torque. The torque which is produced by the interaction between the rotor magnetic field and stator slots, when phase current is zero, is called cogging torque.…”

Background: A number of generator types are used as energy converters in wind turbines. Despite the advantages of PMSG such as high-power density, high efficiency and low speed, the effect of the cogging torque occurring in PMSG must be reduced. Aim: The aim of this study is cogging torque optimization of internal rotor, surface mounted, PMSGs used in wind turbines with high number of slots and poles (84/14). Materials and methods: The performance and cogging torque characteristic of the generator have been studied by the finite element analysis (FEA) method. Results: While the cogging torque value of the initial generator 580 mNm, with changing skew it is optimized to 277.04 mNm, with changing pole arc offset it is tuned to 550 mNm. With a notch on the magnet and teeth it is minimized to 417.25 mNm and 383.9 mNm, respectively. Finally, increasing the ratio of slot opening to slot pitch, undermine the value of cogging torque. Conclusions: The obtained results illustrate that any improvement in cogging torque characteristic using the applied methods accordingly compromises other merits such as flux density, output power, labor and cost.

“…Compared to the internal combustion engine vehicles, electric vehicles contribute significantly to the energy saving and environmental protection, and on account of these benefits, they constitute today's direction for the automotive industry [1]. With growing concerns on environment protection and energy conservation, electric vehicles have gained increasing attention [1][2][3]. Different from the internal combustion vehicles, electric vehicle have an electric motor embedded in the powertrain.…”

<p>This paper discusses about design and analysis of double stator slotted rotor (DSSR) BLDC motor for electric bicycle application. Usually single stator (SS) BLDC motor is used in an electric bicycle. This type of motor has low performance and need to be charged regularly. The objective of this research is to design and analysis DSSR motor that have high torque. At starts, design specification for the electric bicycle is calculated. Next, design process for DSSR is carried out by using the desired parameter. Lastly, analysis for double stator slotted rotor is simulated using FEM. Result for average back emf, average inductance, inner stator flux density, outer stator flux density, average torque and estimate torque constant is obtained. Result for average torque from FEM archieve the requirement of motor torque for DSSR design where the maximum average torque is 16.2 Nm. This research will give benefit to mankind and society in term of environment protection and energy consumption.</p>

“…Double-stator permanent magnet synchronous motors (DSPMSMs) which with high torque density have attracted much attention as described in [1][2][3], but they are three-phase permanent magnet(PM) motors, whose fault-tolerant capability is not sufficient. Fault-tolerant PM motors also have gained more and more attention [4][5][6], but most of them are with single stator and single rotor, whose structures limit the power density further increasing.…”

This paper presents a novel five-phase doublestator permanent-magnet synchronous motor (DSPMSM). The motor is compacted with DSPMSM and fault-tolerant motor, so that the motor not only inherits the merits of double-stator which with high torque density and high utilization rate of the space, but also achieves fault tolerance. A new structure of the rotor is proposed for the DSPMSM. The DSPMSM proposed in the paper poses with high air-gap flux density, torque density and fault-tolerant capacity. Control strategies and electromagnetic torque characteristics of the DSPMSM with completely loss of one and two phases are described. The fault-tolerant performance of the DSPMSM is analyzed by finite element method.
