Abstract

The recent developments in permanent magnet technology and its increased usage in areas involving brushless direct current (BLDC) motors have increased the interest in this motor type. In the study, a 24/8 pole 3 kW brushless direct current motor was designed, simulations were carried out using the finite ele- ment analysis (FEA) method, and an optimization study was carried out using the shifted Hammersley sampling method. Efforts were made to improve the torque ripple and back electromotive force (EMF) values originating from the permanent magnet and the motor design in the BLDC motors. The efficiency of the shifted Hammersley method was validated by the experimental study. The designed BLDC is suitable for applications over a wide range of speeds. The experimental and optimization results both showed that the back EMF harmonics and torque ripples of the BLDC motor under load condition were reduced.
