Sinusoidal Rotor Core Shape for Low Torque Ripple in Hollow-Cup Machines

Due to the configuration of coreless stators and two synchronously rotated rotors, hollow-cup machines (HCMs) enjoy the merits of negligible cogging torque and core loss. Consequently, HCMs have been successfully employed as high-speed electric machines in the aerospace field, which requires high pr...
