“…In principle, the electromagnetic design of AFPM machines is similar to its radial flux PM (RFPM) counterparts with cylindrical rotors. However, the mechanical design, thermal analysis and assembly process are more complex [4]. Specifications of three phase AFWR synchronous generator designed is the nominal quantity (rated).…”

“…The AFPM motor's high torque-tovolume ratio, excellent efficiency and flat structure are especially suited to military and transport applications, and motivate researchers to develop new approaches to design AFPM machines [8,9]. The AFPM machines can be single-or double-sided, with or without armature slots/core, have internal/external permanent-magnet rotors, contain a surface-mounted or interior permanent magnet, and are single-or multi-staged [10]. The AFPM motor cogging torque is normally much higher as compared to conventional motors [11]; however, they can still be potentially applied to high-torque applications such as ship propulsion or flywheel energy storage systems [12,13].…”

Abstract-This paper presents the design and analysis of an inside-out axial-flux permanent-magnet (AFPM) synchronous machine optimized by genetic algorithm (GA) based sizing equation, finite element analysis (FEA) and finite volume analysis (FVA). The preliminary design is a 2-pole-pair slotted TORUS AFPM machine. The designed motor comprises sinusoidal back-EMF waveforms, maximum power density and the best heat removal. The GA is used to optimize the dimensions of the machine in order to achieve the highest power density. Electromagnetic field analysis of the candidate machines from GA with various dimensions is then put through FEA in order to obtain various motor characteristics. Based on the results from GA and FEA, new candidates are introduced and then put through FVA for thermal behavior evaluation of the designed motors. Techniques like modifying the winding configuration and skewing the permanent magnets are also investigated to attain the most sinusoidal back-EMF waveform and reduced cogging torque. The performance of the designed 1 kW, 3-phase, 50 Hz, 4-pole AFPM synchronous machine is tested in simulation using FEA software. It is found that the simulation results fully agree with the designed technical specifications. It is also found from FVA results that the motor temperature reaches at highest temperature to 87 • C at the rated speed and full load under steady state condition.

“…Their cogging torque is usually much larger than that of conventional motors [10], but they could also earn potential to applications such as ship propulsion and elevator direct drive [11,12]. Double-sided AFPM motors are the most promising and widely used type [13]. Topologies for double-sided AFPM machines are axial-flux one-stator-two-rotor (TORUS) and two-stator-one-rotor (AFIR) [14]; either of two arrangements (external stator or external rotor) is practical.…”

Abstract-This paper presents an inside-out axial-flux permanentmagnet brushless DC motor optimized by Finite Element Analysis (FEA) and Genetic Algorithm (GA) that uses sizing equation. The double-sided slotted-stator designed TORUS motor has sinusoidal back EMF waveform and maximum power density. The GA obtained the dimensions that gave the motor its highest power density. Field analysis of the dimensions was then put through FEA, to obtain and re-optimize the motor's characteristics. Possible design parameters were investigated via use of Commercial Vector Field Opera 14.0 software used in three-dimensional FEA simulation and of MATLAB 2010a in GA programming. Techniques such as modifying winding configuration and skewing the permanent magnets were explored to achieve the most-sinusoidal back-EMF waveform and minimized cogging torque. The desired technical specifications were matched by simulation results of the 3D FEA and the GA. The FEA and the GA simulation results comparison of the flux density in different parts of the designed motor at no-load condition agreed well.
