“…In contrast with Equation (9), it can be discovered that there are two other types of MMF except the positive-rotating component in Equation (27), as described in the Part II and Part III. Similar with the fault of one phase open-circuit, the generating currents of the MMF depicted in the Part I, Part II, and Part III of Equation (27) …”

“…In order to increase the power density, many compound-structure PMSMs integrated by two machines have been proposed [25][26][27][28][29], but they are three-phase PM motors, which lack fault-tolerant capability. To combine the advantages of multiphase PM motors and compound-structure PM motors, a novel five-phase dual-rotor PMSM (DRPMSM) is proposed in this paper, which contains two rotors and one stator, as shown in Figure 1.…”

This paper presents a novel five-phase permanent magnet synchronous motor (PMSM), which contains dual rotors and a single stator, equivalent to two five-phase motors working together. Thus, this kind of motor has the potential of good fault tolerant capability and high torque density, which makes it appropriate for use in electric vehicles. In view of the different connection types, the inside and outside stator windings can be driven in series or parallel, which results in the different performances of the magnetomotive force (MMF) and torque under open-circuit fault conditions. By decomposing the MMF, the reason that torque ripple increases after open-circuit faults is explained, and the relationship between MMF and torque is revealed. Then, the current control strategy is applied to adjust the open-circuit faults, and the electromagnetic analysis and MMF harmonics analysis are performed to interpret the phenomenon that the torque ripple is still larger than in the normal situation. The investigations are verified by finite element analysis results.

“…After P e * and P i * have been obtained, they are compared with their measured values, P e and P i , as defined by (2). Two PI controllers then drive the errors to zero by regulating the duty cycles, which are compared with triangle waveforms to produce the PWM gate signals for the IGBTs of the two boost converters.…”

this paper presents a wind turbine concept based on a dual-stator-single-rotor (or sandwich-typed) PMSG and a novel converter. First, the structure of the sandwich-typed PMSG is explained. Then, according to the principle of the PMSG, a novel converter topology is proposed. Finally, a detailed direct drive wind turbine model based on the converter and the PMSG is built in the Matlab/Simulink. Thorough simulation results under different wind conditions verify the effectiveness of the generator+converter combination and the typical functionalities of the wind turbine.

“…Among the interesting combinations, those characterized by a number of slots per pole and per phase equal to 2/5 have been widely considered in the literature (Bianchi et al, 2007;El-Refaie and Jahns, 2006;Ben Hamadou et al, 2009). For instance, machines with 12 slots and 10 poles have been investigated considering two major arrangements of the rotor poles, such that: surface-mounted permanent magnet (SPM) topology, and interior permanent magnet (IPM) topology.…”

Purpose -The purpose of this paper is to investigate the magnetic forces generated by a 12 slot/10 pole concentrated winding PM machines, considering a comparative study between two topologies: a surface mounted permanent magnet (SPM) machine and an interior PM (IPM) machine. Design/methodology/approach -Following a description of the main characteristics of the concentrated winding permanent magnet machines (CWPMMs) under comparison, an investigation of the magnetic forces developed by both machines under study is carried out using finite element analysis (FEA). Findings -A 2D FEA-based investigation has highlighted that the SPM machine develops higher magnetic forces than the IPM one. However, and following a 3D FEA, it has been found that the distribution of the magnetic forces along the air gap of the SPM machine is almost homogenous while it is concentrated in two opposite positions in the air gap of the IPM machine. Research limitations/implications -This work has treated almost all features of the machines under comparison, except the power losses. These should be investigated with emphasis on the PM eddy current losses is so far as the harmonic content of the armature air gap MMF is high. Practical implications -The list of the selection criteria of CWPMMs should be extended to the magnetic force cancellation in order to fulfill the requirements of many applications such as the automotive ones. Originality/value -The paper proposes a combined electromagnetic-mechanical approach to investigate the magnetic forces generated by CWPMMs using 2D and 3D FEA.
