“…There are many possible variations in the AFPM generator design, including single-sided, double-sided, toroidal, and multidisk designs [22][23][24][25]. Among the various machine designs, the double-sided configuration, in which a disk stator winding is sandwiched between two permanent-magnet rotors, is the most popular because of its high-power density.…”

This paper presents the development of an Air‐Cored Axial Flux Permanent Magnet Generator (ACAF PMG) integrated for direct battery charging scheme for urban and rural micro‐wind turbine applications rated at 1 kW. The proposed generator has a Single Stator Double Rotor configuration with a relatively short axial length. In this paper, the analytical model for generator sizing is presented and the main parameters are defined. Novel analytical model is presented to determine the required number of turns for each phase in order to produce a balanced voltage in the three phases. The generator is electromagnetically analyzed using Finite Element model and simulated using Matlab/Simulink to predict its performance under several operating conditions. The effect of retainment ring type on the generator performance is also demonstrated. The machine is harnessed to a battery bank via a three‐phase fully controlled converter using six bridge thyristors to regulate the output voltage delivered from the generator to the battery. Generator model and simulation results are validated via experimental tests. The preliminary experimental results showed a good match with the simulation results. Moreover, the proposed machine is compared favourably with other counter machines of similar configuration and power ratings in terms of machine size, power‐to‐weight ratio, and voltage regulation. This paper therefore demonstrates the concrete benefits of utilizing the axial flux PMG in scavenging energy to generate electrical power from micro wind turbines.

“…AFPM machine rotors may come with trapezoidal, cylindrical or semi‐cylindrical magnets. Magnet topology has a great effect on manufacturing cost, magnetic flux distribution, and structural design [24]. In a like manner, their stator coils can be trapezoidal [27], circular [30], and rhomboidal [31].…”

“…Axial flux permanent magnet machines (AFPMM) are increasingly popular in the last decade due to their compactness and high degree of reliability and high-power density [1][2][3][4][5][6][7]. Different topologies are available, namely single sided (one stator and one rotor), double sided (single stator-double rotor or single rotor-double stator) and multistage (multiple rotors and stators).…”

Thermal analysis of a coreless axial flux permanent magnet machine

The article deals with numerical analysis of a double sided coreless axial flux permanent magnet machine with two rotor disks and a coreless stator. Coreless stator represents copper windings which are held together by epoxy raisin, therefore a special focus has to be given to the stator temperature. In this article a numerical analysis is presented, which is based on the copper losses, namely the I2R product, where the resistance of the copper windings was both calculated as well as measured in the prototype machine.
