“…Optimizing the winding structure of the stator geometry by analyzing the winding connections, pole numbers, and wire diameter with a finite element software may enhance the spindle motor's maximum torque and efficiency [5]. Previous research has successfully performed optimal design on stator configurations with various methods such as using response surface methodology (RSM) [5], multiobjective optimization [2], [6] and Ansys software [7], [8] to optimize the stator teeth width, yoke width, air-gap length, bore diameter, bridge distance, and slot openings. The subsequent stator winding design, which involves coil turns, winding configuration, and winding connection form for the high-efficiency motor was conducted by Rossi et al, [9].…”
