brushless DC (BLDC) motor causes torque ripple and speed fluctuations. It can interfere with
motor operating performance because it will not rotate smoothly due to noise and vibration,
especially at low rpm. Therefore, the cogging torque must be reduced or eliminated to
improve the operating performance of the BLDC motor IPM V-Shape designed and built.
Several studies have shown various ways to reduce or eliminate cogging torque. This paper …
