“…References [2,3] reported that by integrating a magnetic gear with a PM machine, the resultant magnetic geared machine can be used as generators in low-speed renewable energy power generation applications. References [4,5] reported in some studies that permanent magnet (PM) machines with a double-stator topology achieved greater performance characteristics than conventional single-stator permanent magnet machines. The research on magnetic geared double-stator PM machines has steadily increased recently in the last 10 years, although very few studies have been conducted on this class of MG machines.…”

Abstract-This paper presents the power density evaluation and power mapping performance of a novel magnetic geared double-stator permanent magnet generator (DSPMG) which is proposed to address problems of mechanical geared generators for low-speed power generation applications. The operating principle is based on three PM rotors consisting of prime permanent-magnet (PM) poles in the middle rotor and field PM poles in the inner and outer rotors respectively. To evaluate the power density performance, a 2-D finite-element method (FEM) is used to predict the performance of the generator, and a demonstrator prototype is fabricated and evaluated experimentally. The power density characteristics of the proposed generator are analyzed and reported. The measured results agree closely with the simulated ones to verify the validity of the magnetic geared generator design. Finally, a measurable comparison is conducted with other published prototype magnetic gear machines to demonstrate its benefits of higher power density and smaller volume size.

“…A three-phase double-stator cup-shaped rotor for wind power generation with optimal pole-to-slot ratio produces low torque ripple [14]. A three-phase generator with a permanent magnet mounted on both the inner and outer surfaces is proposed in [15]. It reduces the length of the magnetic path that saves the iron yoke material resulting in increased power output.…”

Abstract-The improvement in the power density in the double stator configurations is feasible with increase in the electrical loading of the electrical machines. This type of newer configuration is finding significant applications in improvising energy generation, more commonly for renewable energy generation. Various double stator configurations with non-arc permanent magnet machines for power density are modelled and analyzed in this paper. Finite Element Method (FEM) is used to simulate for the generation capability including the electromagnetics parameters such as flux linkage and open circuit voltage. A new slotted rotor structure is evolved based on the magnetic flux flow control inside the machine. The proposed structure is then fabricated in the laboratory and tested for operating characteristics with load circuit. The proposed machine produces a maximum power of 600 W at speed of 2000 rpm with 75% of maximum efficiency with the micro-hydro generation unit.

“…In [3,4], both the thrust density and power factor of the PMV motors has been improved by employing spoke magnets. In recent years, Vernier PM motor is attracting more and more attention due to their simple mechanical structure, high torque density, sinusoidal back electromotive force (EMF) waveform, and low pulsation ripple [5][6][7][8][9][10][11].…”

Abstract. In this paper, a novel linear permanent magnet vernier (LPMV) motor is proposed. The advantages of the proposed motor are high force density, high efficiency, simple structure, and low cost. Firstly, the structure and the operation principle of the proposed motor which adopts 12-slots-11-pair-poles structure are descried. Based on the air-gap permeance function, the components of air-gap flux density is discussed. Secondly, the validation of LPMV is analyzed by finite element method (FEM), and the basic electromagnetic performance such as air-gap flux density, back-EMF, detent force and thrust waveform are analyzed in detail. Finally, the relationship between the thrust force characteristics and the design parameters are analyzed to provide useful information to the designers of LPMV.
