چکیده :

In the operation of PMaSynRM, the generated torque ripple can lead to the production of acoustic noise and vibration. It is important to take this into consideration to minimize any potential negative effects on the systems, especially in electric vehicle applications. The study investigates the torque produced by a PMaSynRM and highlights the effect of geometry bifurcation on torque ripple and average torque. This paper presents a motor design with different bifurcation shapes of stators, such as the circle, triangle, and gear shapes, and the rotor, which can be trapezium or triangle-shaped. Eleven design patterns with different width and height were analyzed for each one, and the performance of the motor in different patterns were compared and the best one was selected based on the 2D finite element method FEM. The simulation results indicated that when the stator teeth notch is circular in shape and the rotor pole groove is trapezium-shaped, the electromagnetic torque is reduced by 5.27%, and the torque ripple is minimized by 63.58% compared to the base design.
