This paper presents a non-linear analytical model of a multi-V-shape Interior Permanent Magnet (IPM) motor with non-overlapping concentrated winding. The model relies on Ampere's theorem and the flux conservation law in order to compute the flux density in the different parts of the motor. This article proposes a saturated analytical model of the stator and the rotor. The analytical model is used to calculate the average torque, the power factor and the voltage of the motor. It is 5 times faster than the 2D Finite Element Analysis (FEA). The results are compared to 2D FEA simulations and experimentally validated using a prototype motor.Index Terms-Analytical model, Concentrated winding, Electrical machines, IPM motor, Multi-V-shape magnets.Average torque [Nm] Power factor Voltage [V]

“…This article proposes a saturated analytical model of the stator teeth and the stator yoke. It takes into account the leakage flux in the slots and the saturation in the rotor magnetic circuit [12]. The developed model is parameterized as a function of the slot number, the pole pair number and the magnet layer number.…”

In this paper a multi-physics model is proposed for a multi-V-shape Interior Permanent Magnet (IPM) motor with concentrated winding. This work develops a non-linear magnetic model that computes the flux density in the motor. The analytical model includes several novel aspects: it takes into account the local saturation near the iron bridges, it proposes a method for modeling the concentrated tooth winding, it calculates the slot tangential leakage flux and includes it in the flux linkage calculation. 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 developed in order to calculate the copper and the iron losses. They are used as inputs to a nodal thermal model that introduces a thermal circuit for concentrated end-winding and computes the temperature of the motor. A mechanical model is developed. It evaluates the mechanical constraints encountered by the structure. The models are verified using finite element computations and numerical calculations performed with dedicated software. Besides, the coupled analytical model is experimentally validated using a prototype motor. Finally, two multi-physics bi-objective optimizations are carried out in order to design the motor for high torque and low speed application.

“…The previous analysis has been carried out neglecting both: (a) the stator slotting effect, and (b) the magnetic iron saturation effect. These phenomena strongly affect the air-gap flux density distribution [10]- [12]. In fact, some dips appear in the air-gap flux density distribution due to the magnetic reluctance variations in the air-gap caused by the slot openings [13]- [16].…”

“…In addition, the magnetic voltage drops, occurring in the stator and rotor iron, limit the magnetic fluxes flowing through the iron parts of the motor. As a consequence, the flux density variations in these regions are reduced [10], [17]. It has been observed that the iron losses computed in [9] result to be overestimated, especially if they are computed along the MTPA trajectory.…”

Synchronous reluctance machine has high flux density fluctuations in the iron due to the high harmonics results from the rotor anisotropy. Thus, an accurate computation of the iron losses is of paramount importance, especially during the design stage. In this paper, a non-linear analytical model considering the magnetic iron saturation and the slotting effect is proposed. The model estimates accurately the iron losses at a wide range of operating speed. In addition, the accuracy of the non-linear model when the machine is highly saturated, i.e. when it works along the MTPA trajectory, is presented and verified. The model presented is general and can be applied to other configurations. A 36-slot four-pole machine, with three flux-barriers per pole is considered as a case study. Finite element analysis is used to validate the results achieved by means of the non-linear analytical model. Furthermore, an experimental setup is built to validate the simulation results.
