Design of 6S8P axial flux permanent magnet brushless DC motor with double-sided rotor

Abstract

Electric motors developed rapidly in this decade. That is because electric motors have many advantages over conventional engines. The types of electric motors also vary, from low rated power to high rated power. Electric motors become an essential part of many sectors, such as industry and transportation. Brushless Direct Current Motor (BLDC) is one of the electric motors that has been developed because it has advantages compared to BDC motors. Low-power BLDC motors are widely used in several fields, such as computer construction, robots, and aviation. Research on the form of BLDC motor construction needs to be done to find out the maximum performance of a BLDC motor. Testing of a small motor axial flux permanent magnet brushless direct current with the double-sided rotor (AFPM BLDC DR) was carried out to determine the values of rotational speed, torque, mechanical power, and efficiency. Based on the test, a maximum rotational speed of 2365 rpm, the torque of 0.055 Nm, and the effectiveness of 70.34% are obtained.
