“…A micro wind energy system consisting of a small wind turbine coupled with a single-phase, single-stage, 8-pole AFPMG has been presented and the power density parameter of the AFPMG has been improved [4]. The AFPMGs have been fabricated by using magnets from redundant materials like hard disks and the performance of the AFPMGs has also been evaluated [10]. An AFPMG having a single-stator single-rotor topology with a coreless stator disc has been proposed [11].…”

Presently, axial flux permanent magnet machines are becoming popular and are being deployed actively for low speed applications. This paper presents an improved model of a multistage axial flux permanent magnet generator (AFPMG). The multistage AFPMG consists of multiple stator and rotor discs. There are three identical 1-phase stator discs and four in-phase rotor discs in the proposed multistage AFPMG. In this research, 4 case studies were analyzed on the design of the multistage AFPMG. First, a phase shift model (PSM) positions the three 1-phase stator discs to behave as a 3-phase generator. Actually, the PSM computes phases for three stator discs in order to establish phase shift of 120• between each two phases. The implementation of the presented model in the multistage AFPMG reduces the diameter of the stator disc three times as compared to the conventional 3-phase AFPMG with identical rated specifications. Second, the voltage waveform of the AFPMG was analyzed for harmonic contents and the percentages of 3rd and 5th harmonics were computed. The test results show that 3rd and 5th harmonics were reduced to 10.7% and 0.54%, respectively, in voltage waveform. Third, the proposed multistage AFPMG was designed considering begin-to-end winding connections of the stator disc. While adopting begin-to-end connection, the number of poles of the AFPMG are doubled, which ultimately increases air-gap flux density and thus the terminal voltage of the stator disc and operating shaft speed is halved. The test results show that the torque-to-weight ratio parameter of the designed AFPMG was improved by using a begin-to-end connection for the stator disc. Fourth, the increased air-gap flux density also improves the power density parameter of the AFPMG with a begin-to-end winding connection.Moreover, a prototype model of a 1200-W multistage AFPMG was designed and fabricated while following PSM and begin-to-end winding connection and tested. Thus the test results verify the proposed model of the multistage AFPMG for wind turbine applications.

“…Axial-flux machines (AFMs) are increasingly used in many applications such as small direct-drive wind power generation systems [1][2][3], flywheel energy storage system [4], electric vehicles [5][6][7][8][9], Electric scooters [10], aircraft [11] pumps [12], domestic applications [13][14][15], fans, and food processors. Although in many applications, permanent magnet (PM) machines have merit to be superior to induction machines, they have some intrinsic challenges.…”

Summary In this paper, design and prototyping of two‐speed capacitor‐run single‐phase axial‐flux induction motor (AFIM) for direct‐drive applications is presented. The proposed structure has single stator‐single rotor configuration with high magnetic pull between the stator and rotor, which may compel rotor to lock. Although the most efficient method to overcome this problem is using a second rotor or stator in the mirror with the first one, it is not applicable in low‐cost applications. So, in this paper, two new and fast construction techniques are proposed to fabricate an AFIM with extra low air‐gap length and minimum cost. Beside design and optimization process, a thermal equivalent circuit considering radial and lateral heat transfers is proposed. Then different losses and thermal resistances are exactly calculated to estimate the temperature rise of different motor parts and the maximum specific magnetic and electric loadings. Then, motor performance is evaluated using three‐dimensional time‐stepping finite‐element analysis. Finally, a comprehensive fabrication algorithm for AFIMs is presented, and a prototype of the studied motor is fabricated and tested. The experimental results validate the design, optimization, thermal model, and finite element simulations. Copyright © 2016 John Wiley & Sons, Ltd.
