    Design of A High - Efficiency Inner-Rotor Permanent Magnet Brushless Direct Current Motor for General Applications
    (Bursa Teknik Üniversitesi, 2025) Köksal, Halil Ercan; Corapsiz, Muhammedfatih
    In this study, it is aimed to design a Brushless Direct Current Motor (BLDC) with higher efficiency, speed and torque stability compared to asynchronous motors in applications such as fans, propellers, pumps, drills, lathes, ventilation, where asynchronous motors are generally used. The basic sizing parameters of the design were determined analytically, magnetic analysis and optimization of the dimension parameters were carried out through the ANSYS Maxwell program using the Finite Element Method (FEM). Since the designed BLDC is intended to be for general use and does not need additional cooling equipment, the output power is chosen as 1.5kW. The rated speed is determined as 1500 rpm in order to reduce switching losses. The design was tested by simulating different groove and pole numbers in the ANSYS Maxwell program and the highest efficiency was obtained with 9 grooves – 8 pole matches. Therefore, the motor is designed with 9 grooves and 8 poles.
