Abstract-This paper discusses design synthesis of a permanent magnet brushless DC (PMBLDC) machine using a finite element (FE) model. This work differentiates itself from the past studies by following a synthesis approach, in which many designs that satisfy performance criteria are considered instead of a unique solution. The designer can later select a design, based on comparing parameters of the designs, which are critical to the application that the motor will be used. The presented approach makes it easier to define constraints for a design synthesis problem. A detailed description of the setting up of a FE based design synthesis problem, starting from the definition of design variables, FE model of the machine, how the design synthesis is carried out, and to, how a design is finalised from a set of designs that satisfy performance criteria, is included in this paper. The proposed synthesis program is demonstrated by designing a segmented axial torus PMBLDC motor for an electric two-wheeler.Index Terms-Axial flux machines, PMBLDC motor, finite element model, electrical machine design synthesis, segmented stator tooth, integer constrained genetic algorithm.

“…AFPM machine has higher torque and power density, as compared to the RFPM machine [4,5]. Coreless AFPMSG has high efficiency due to the absence of stator core losses, and a reduced total harmonic distortion (THD) in the back EMF [5,6]. Moreover, the dual rotor coreless generator has greater mechanical stability due to the reduced axial force of attraction between the stator and rotor, and it is also easy to manufacture [7,8].…”

In this paper, model of the axial-flux permanent magnet synchronous generator (AFPMSG) having arc-shaped trapezoidal permanent magnets (PM) is presented. The proposed model reduces the cogging torque and torque ripple, at the expense of lowering the average output torque. Optimization of the proposed model is performed by considering the asymmetric overhang configuration of the PMs, as to make the output torque of the proposed model competitive with the conventional model. The time stepped 3D finite element analysis (FEA) is performed for the comparative analysis. It is demonstrated that the torque ripple of the optimized model is highly reduced as well as average output torque is increased.
