This article proposes a torque optimization method that introduces the rotor magnetomotive force (MMF) harmonics. aiming to increase the average torque without increasing the cogging torque and torque ripple. A spoke type permanent magnet direct drive motor with fractional slot concentrated winding (FSCW) is designed. The FSCW can improve the utilization rate of the winding. https://ashleyshomestores.shop/product-category/dishwasher-cleaner/
