“…The armature-reaction field is calculated by introducing a current sheet, shown in Figure 5. The equations for the flux densities resulting from this current sheet are described in [13]. The inverse transformations (from the T-plane back to the Z-plane) result in a complex permeance function SC ( , ), which is discussed in more detail in [13].…”

“…The mapping is done via a more complex Schwarz Christoffel (SC) transformation that is capable of obtaining both radial and tangential components of the flux density of the machine in both directions. The technique has been adopted in [13] to be used for AFPMSMs. This class of models is called SC models.…”

A comparison between different analytical and finite-element (FE) tools for the computation of cogging torque and torque ripple in axial flux permanent-magnet synchronous machines is made. 2D and 3D FE models are the most accurate for the computation of cogging torque and torque ripple. However, they are too time consuming to be used for optimization studies. Therefore, analytical tools are also used to obtain the cogging torque and torque ripple. In this paper, three types of analytical models are considered. They are all based on dividing the machine into many slices in the radial direction. One model computes the lateral force based on the magnetic field distribution in the air gap area. Another model is based on conformal mapping and uses complex Schwarz Christoffel (SC) transformations. The last model is based on the subdomain technique, which divides the studied geometry into a number of separate domains. The different types of models are compared for different slot openings and permanent-magnet widths. One of the main conclusions is that the subdomain model is best suited to compute the cogging torque and torque ripple with a much higher accuracy than the SC model.

“…This LPMC model construction is simple because there is no PM in switched reluctance machine. In [8][9][10][11][12][13][14][15], the LPMC models for doubly salient PM, axial-flux PM, spoke-type PM and flux-switching PM machines were built. The magnetization directions of their PMs are tangential.…”

Abstract-Permanent-magnets (PMs) with tangential and parallel magnetization directions are combined in the Halbach PM (HPM) machine, which can offer high performances. However, the existing lumped parameter magnetic circuit (LPMC) model can only calculate one PM magnetization direction, namely either tangential direction or parallel direction. The key of this paper is to propose a method to divide and establish equivalent magnetic motive force (MMF) for HPM machine with both tangential and parallel magnetizations. Then, a LPMC model, using equivalent MMF, is developed to predict the electromagnetic performances for a four-phase HPM machine. In order to verify the effectiveness of the proposed LPMC model, a 6-pole/8-slot 15 kW HPM prototype is built. The comparative results of the proposed LPMC model, two-dimensional (2D) FEM and the experiments verify the effectiveness of the proposed LPMC model.
