High cogging torque
Web31 de mai. de 2024 · Abstract: To suppress high cogging torque and torque ripple of stator-permanent magnet flux-switching (SPM-FS) machines, three functional-contour salient pole rotors (FSPRs) are proposed and designed, where the rotor tooth top contours conform to , and respectively. Web9 de fev. de 2024 · However, this is not the definition of cogging. Cogging is a result of the iron core in a brushless motor reacting with the permanent magnet within the motor. As you rotate a motors output shaft, you can feel the “steps” of the motor through one full revolution. These steps require a certain amount of torque to overcome the resistance.
