“…The model's complex magnetic circuit was analysed for an overall view of the saturation levels in various parts of the motor, and to extract the motor's characteristics. An advantage of 3D-FEA is that various components of flux density can be calculated highly accurately [32][33][34][35][36][37][38][39][40]. The design was simulated on commercial ANSYS 13.0 software [41].…”

Abstract-This paper presents the design, analysis, and prototyping of a novel axial-flux permanent-magnet (AFPM) motor capable of auto-starting. The preliminary design is a slot-less double-sided solid-rotor line-start AFPM motor with 4 poles for high torque density and stable rotation. One spaced raised ring was added to the inner radii of the rotor disc for smooth line-start motor. The design allows the motor to operate at both starting and synchronous speeds. The basic equations for the solid ring of the rotor of the proposed axial-flux permanent-magnet motor are presented. Nonsymmetry of the designed motor led to its 3D time-stepping finite element analysis (FEA) via ANSYS 13.0, which evaluated the design parameters and predicted the transient performance. The designed motor was fabricated and tested, the experimental results showing good agreement with FEA simulation results. The prototype motor showed high starting torque and good synchronization.

“…The generator under investigation is a low and variable speed machine with a large pole pair number. Such a machine has concentrated windings and therefore the third spatial harmonic component is not negligible [2][3][4]. This component is generated by the third harmonic of the windings specific electric loading.…”

Abstract:In this paper the MTPA, MTPF, constant torque and constant flux control trajectories are presented. These trajectories are calculated for a 6-phase asymmetric insettype SMPMSM generator with the assumption of a certain level of 3rd harmonic current injection. This injection technique increases the generator performance due to the cooperation of the fundamental and 3rd harmonic. The presented trajectories are used for fast control of the generator working in the gearless wind turbine system.

“…So, the so-called one-airgap topology is deduced as shown in Figure 12(c). When the number of ferromagnetic pole-pieces is integer multiple of the number of stator teeth, a particular one-airgap MGPM machine can be obtained and has been analyzed [50,51], which is actually similar to the PM vernier machine [52,53]. Compared with the three-airgap topology, the operation of the two-airgap and oneairgap topologies relies on the flux modulation, namely the number of pole-pairs of stator armature winding should be equal to the number of pole-pairs of the modulated harmonic rather than the PM pole-pairs on the outer rotor.…”

Abstract-With the advent of magnetic gears, researchers have developed a new breed of permanent-magnet machines. These magnetic-geared permanent-magnet machines artfully incorporate the concept of magnetic gearing into the permanent-magnet machines, leading to achieve low-speed high-torque direct-drive operation. In this paper, a quantitative comparison of three viable magnetic-geared permanent-magnet machines is firstly performed, hence revealing their key features, merits, demerits and applications.Initially, the development of the magnetic gears, including the converted topologies and field-modulated topologies, is reviewed. Then, three viable magnetic-geared permanent-magnet machines are identified and discussed. Consequently, the corresponding performances are analyzed and quantitatively compared. The results and discussions form an important foundation for research in low-speed high-torque direct-drive systems.
