“…However, the low magnetic field created by these types of magnet leads to their use as an additional torque source in synchronous reluctance motors. This configuration is known as the Permanent Magnet Assisted Synchronous Reluctance Motor [3] - [5]. In previous work [6], we proposed to study an 18 slots and 16 poles radial flux motor with two V-shape barriers per pole filled with ferrite magnets with non-overlapping concentrated winding.…”

This paper presents a noval 18 poles /16 slots Axial Flux Permanent Magnet-Assisted Synchronous Reluctance Motor (AF-PMASynRM) with non-overlapping concentrated winding. At first, the torque ripple and iron losses are analyzed using 3D Finite Element Analysis (3D-FEA). Then, a comparison between 3D-FEA and 2D-FEA based on flux and iron losses is established. In this paper, we propose to design the motor for high torque low speed application using a multiobjective optimization. In this kind of iterative procedure, the use of Finite Element is generally time consuming. Thus, we propose a 2D analytical saturated model that considers the local saturation near the iron bridges and the slot tangential leakage flux. The magnetic model is coupled with an electrical model that computes the power factor and the voltage at the motor terminals. A loss model is also developed to calculate the copper and the iron losses. The proposed analytical model is 5 times faster than the 2D-FEA. The optimal axial structure is compared to a previously optimized radial motor in order to evaluate the design benefits of axial flux machines.

“…is strictly linked to reactive power needed to magnetize the rotor, hence low interaction among axes is a key point. Numerical indications of this aspect have been provided in [7]. A careful sizing of iron ribs can have huge impact on this parameter.…”

Current industrial trend shows a growing care towards energy efficiency. Some rotor technologies, such as Synchronous Reluctance and PM-assisted Synchronous Reluctance, are revealing their potential for sustainable costs and environmental safety. These technologies use very high saliency designs with large empty parts in rotor lamination, leading to small highly stressed mechanical parts in the rotor structure ("bridges" or "ribs"), whose dimensions in turn affect performance. Aim of this work is a trade-off analysis of electromechanical design for PM-assisted Synchronous Reluctance motors, investigating different configurations and strategies for iron bridge sizing.

“…These designs guide the flux to flow in chosen directions, as to enhance the air‐gap flux density. This technology can be applied to variable types of machines such as synchronous reluctance machines [7–9], wound‐rotor synchronous machines [10], and stator wound‐field synchronous machines [11]. However, adding the flux barriers and magnets gives rise to the complexity and manufacture cost of the rotor.…”
