Enhancements to the Work Ability of a High-Speed Motor Used in Machine Tools

Summary/Abstract: This paper presents a strategy for maximizing the effectiveness of high-speed spindle motors in manufacturing equipment. Using the ideal design of the stator winding geometry, as calculated by the Taguchi method, we were able to increase the maximum torque and efficiency. The rotor slot geometry was optimized using a response surface to raise the starting torque and reduce the starting current. The objectives of this investigation were to come up with a strategy for designing high-speed spindle motors so that they have better performance in terms of starting torque, maximum torque, efficiency, and starting current. Spindle motor temperature rise was the focus of the thermal measurements. Finally, a working spindle motor prototype was built and tested to verify the results of the Finite element analysis (FEA). The validity of the suggested model is demonstrated by a comparison between experimental measurements and finite element findings. The total percentage of mistakes was close to 2%.
