Investigation of Noise Sources in Fractional-Slot Concentrated Winding Motors Considering High-Order Radial/Tangential Electromagnetic Force Combination and Modulation
Traditional methods equate the slotted stator as an unslotted model and employ an approximation where the stator deformations are considered inversely proportional to the fourth power of the order of air-gap electromagnetic force density (AEFD).This approach effectively overlooks the contributions of high-order forces.Furthermore, it overlooks the
