“…Therefore, it was decided to create a simple analytical model, which takes the steel saturation into account (lumped model). The analytical model was verified by FEM, concerning the average output torque, with good agreement in [15]. However, a deeper analysis and verification of the model is given in this paper.…”

“…Therefore, the armature current should not have an essential influence on the rotor steel magnetic state. However, as it is noted in [17], [15], the tooth-tip leakage inductance, the slot leakage inductance and the air-gap leakage inductance have significant contributions to the total synchronous inductance of the TCW PMSM. Therefore, it can be concluded that in PMSMs with rotor surface permanent magnets, the performance deterioration is mainly caused by the steel local over saturations in the stator side, but not in the rotor.…”

“…The detailed description of the model can be found in [15], where it was shown, that the lumped model can precisely follow the performance results of the TCW PMSM found by . R leak is the total slot leakage reluctance, Rsy is the stator yoke reluctance, Rst is the stator tooth reluctance, R δ is the air gap reluctance, Rpm is the permanent magnet reluctance, θ PM is the permanent magnet current linkage, θw is the stator winding current linkage.…”

This paper describes an optimization of the stator geometry in a way that the torque ripple at particular load is reduced.The principle applied to the torque ripple reduction is based on the synchronous inductance variation suppression, caused by the non-linear steel saturation, which might be significant even in permanent magnet synchronous motors (PMSMs) with rotor surface permanent magnets.The design optimization, described in this paper, aims in reducing the armature reaction influence on the local steel saturation in fractional slot permanent magnet synchronous machines (FSPMSM) by rearranging of the stator teeth widths.The optimization was defined by means of magnetic equivalent circuit model (lumped model), and verified with finite element method (FEM).

“…Even if some types can reach a unit winding factor, such as the full pitched type, this work opted by the fractional slot non-overlapping winding. The advantages are a simpler and cheaper manufacture, low cogging torque, good fault tolerance, large constant power region and high fill factor possibility (Petrov et al, 2014). Furthermore, this solution reduces the coil head, which also reduces Joule losses and the total machine length, affecting efficiency and mass.…”

This paper discusses in-wheel electric tractive systems, bringing as a case study the finite element design of a Fractional Slot Permanent Magnet Synchronous Machine with non-Overlaping Winding (FSPMSM) for an all-wheel drive Formula Student powertrain. The goal is to obtain a system that fits a 10” rim wheel, with a high power density that enables a 280 kg vehicle to accelerate over 75 meters in less than 4 seconds. Iterating the design method to maximize the output torque, the simulations indicate that a single 12,000 rpm machine can provide continuous 17.7 kW at the 600 Vdc system.

Purpose – An analytical sub-domain model is developed for predicting the armature magnetic field in permanent magnet vernier machine (PMVM) which has either non-overlapping or overlapping windings. The developed model accounts for tooth-tips and flux modulation pole slots (FMPs). The paper aims to discuss these issues. Design/methodology/approach – It is obtained by solving Poisson’s and Laplace’s equations in polar coordinates for each sub-domain, i.e. air gap, slots, slot openings at tooth-tips and FMP slots. Armature reaction field distributions in slots, slot openings FMPs, air-gap and magnet region and winding inductances are obtained from the analytical method and compared by finite element analysis. Findings – It is found that the developed model can be employed to accurately predict the armature field and winding inductance for any combination of slots/FMPs/permanent magnets. In addition, it is observed that the winding inductance is high which results in significant armature reaction and poor power factor in PMVM. Originality/value – The main contributions include: first, accurate sub-domain model for PMVM is proposed for armature reaction which is not addressed in literature; second, the model accounts the interaction between FMP and slot; and finally, developed sub-domain model is also used for inductance calculation.
