“…These parameters are stator slot opening at the slot tip (B s0 ), at the wedge (B s1 ), at the bottom (B s2 ), height of stator tooth tip (H s0 ), slot wedge (H s1 ), from wedge to slot bottom (H s2 ). Considering the slot area given in Equation ( 6), B s1 and B s2 can be calculated from Equations (10) and (11).…”

“…With decreasing the slot width, the interbar current and thus the stray losses in the rotor increased 10 . When the effect of the stator slot opening on the performance of the axial flux multi‐pole motor was examined, it was determined that the efficiency in the open slot structure decreased by 6% 11 . In a different study, the stator tooth structure of a superconducting permanent magnet generator was investigated for wind turbines.…”

From the point of production to consumption, electrical energy should be utilized effectively and qualitatively. Efficiency at the electricity consumption stage is not sufficient, and the desired criteria must be met at the production stage. The efficient and high‐quality generation of electrical energy is directly related to the performance of the generator used. In order to achieve the desired criteria for a generator design, many issues should be considered together. In order for this study to do, a 14‐pole and 5 kW permanent magnet synchronous generator (PMSG) was designed using the innovative optimizer named the weighted mean of vectors (INFO), the jumping spider optimization algorithm (JSOA), the teaching–learning‐based optimization (TLBO), the pelican optimization algorithm (POA) and the teaching‐learning‐studying‐based optimization (TLSBO) algorithms. The generator performance was optimized within the determined inequality constraints by the offset and embrace value and six parameters of the stator slot structure. The generator designed with the parameters determined by the TLSBO was more successful than the generators designed according to all the other proposed algorithms. The total harmonic distortion (THD) value decreased by 51.983% compared to the initial design at approximately the same efficiency.

“…It is possible to vary the air‐gap magnetic flux density, back electromotive force and torque characteristic of the motor using different types of stator slots. The optimum stator slot size is determined during motor design and depends on a mission‐specific objective [4–6]. In addition, the different opening widths of the stator slots will affect stator core loss, winding loss and rotor eddy current loss for stator [7, 8].…”

The structure of a permanent magnet synchronous motor (PMSM), more precisely, its shape and dimension of the stator slot can change the magnetic field distribution of the stator tooth and the yoke. In addition, it also affects the magnetic field distribution in the air‐gap and the electrical loss in the rotor. As a result, there is an effect on the motor's internal temperature distribution. This study aims at investigating the influence of stator slot dimension on the performance of the motor. To this extent, a field‐circuit coupled model combining the vector control strategy with motor finite element model is proposed. Based on this model, the impact of using various opening widths of semi‐closed slot and the dimension of the closed slot on both magnetic field distribution and loss in the PMSM is studied in detail. Furthermore, by considering the calculated loss as a heat source, the temperature variation of the stator core, winding, magnetic bridge and permanent magnet of the motor for different scenarios of slot dimensions can be obtained by using a three‐dimensional temperature field model at steady‐state. An experimental platform is established to validate the model this provides a theoretical support for the analysis of the results.
