Reduction of cogging torque in segmented permanent magnet BLDC motor IPM v-shape by skewing stator

In the case of the Internal Permanent Magnet V-Shape motor, the cogging torque on a 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 will analyze and apply one of the methods to eradicate cogging torque: The Skew Method in the BLDC motor IPM V-Shape stator through Finite Element Analysis (FEA) simulation ANSYS Maxwell. It will also analyze the motor’s torque, speed, and efficiency to determine the effectiveness of the Skew Method on the stator of BLDC Motor IPM V-Shape. The result shows that the Skew Method in the BLDC Motor IPM V-Shape can reduce by almost 100% of cogging torque and produce a motor design that has good performance.
