Description
Summary:	The BLDC motor is preferred for different industrial applications due to the advantage of high speed range, higher proficiency, enhanced dynamic response and longer life. BLDC motor have high torque ripple. Major reason for this torque ripple is cogging torque. This work shows the investigation and design optimization for decreasing the cogging torque by changing the stator teeth tang span to alternate the shape of stator teeth. It results in Peak to peak reduction of cogging torque. Hence the vibration and noise are minimized. The analytical design of the proposed system is completely analyzed using Finite Element Method (FEM) and the simulation is performed using MagNet software.
