A Various technique is available in reducing the cogging torque in Brushless DC machine (BLDC). Cogging torque is the main hindrance in BLDC motor, which results in direct impact on the performance of the Permanent Magnet (PM) motor. In this paper the PMs has various structures such as surface mounted, interior and buried permanent magnet. The cogging torque is compared for the various designs of the rotor structures. The CAD package validates the design and shows the performance enhancement of BLDC motor.
