“…The magnetic dispersion flux of a TPIC can be divided into specific components, each exerting a dispersion effect at different points within the machine. During the energy conversion process, the magnetic flux traverses the air gap, where residual flux can be dispersed either midway or on the surface of the rotor [6][7][8]. However, a distinct dispersion of magnetic flux typically concentrates in the stator slot region.…”

Electric vehicles have become more widely used in the market given their numerous benefits. Electric motors should be optimized for optimal development and application. High-performance slot topologies, including rounded, rectangular, or mixed configurations, have already become established in the market, showing excellent results in terms of final induction motor performance. Consequently, new slot topologies, be they for the stator or for the rotor, can offer several advantages. These new topologies may facilitate greater magnetic flux or reduce magnetic flux dispersions. These enhancements result in increased efficiency for electric vehicle induction motor applications. This study examines the performance of a three-phase induction motor intended for use in a light electric vehicle propulsion system. The focus is on altering the stator slot plate topology to gauge its impact. The analyses compared the magnetic flux dispersion for three different slot topologies. The original stator slot design featured a flared shape, which was compared with a rectangular slot design. The COMSOL software program allowed us to visually represent the generated magnetic field lines within the induction motor. This included the magnetic flux dispersion lines, categorized as either gap dispersion, slot dispersion, coil head dispersion, slot tooth dispersion, and slope dispersion. With the MATLAB software program, we performed a quantitative analysis of the magnetic flux dispersion for the three stator slot topologies. The induction motor equipped with the rectangular slot showed a 0.13 \% efficiency gain compared to the motor with the original slot design.
