Electric motors are one of today's technological innovations. An electric motor is a machine or device that converts electrical energy into mechanical energy. BLDC motor is one type of electric motor that is often used in everyday life. BLDC motors are an alternative to the shortage of AC and DC electric motors. This study discusses the performance of a brushless direct current motor 3 phase axial flux 3 stator 2 rotor with star and delta connections. The purpose of this study was to determine the effect of the addition of a stator and rotor on motor rotational speed and torque and to determine the best performance of a 3 phase axial flux BLDC motor when star and delta connection. This study uses 3 stators and 2 rotors. In the stator, 6 coils are installed, each coil consisting of 450 turns with a wire size of 0.3 mm. While the rotor uses neodymium magnets with magnetic dimensions of 15 mm x 15 mm x 5 mm as many as 16 pieces. The test was carried out 5 times with a voltage source starting from 11 V to 24 V. The first test was testing a brushless direct current 3 phase axial flux motor with 1 stator and rotor construction producing a rotational speed of 739 RPM to 1940 RPM and a torque of 0.0327 Nm to 0.0424 Nm. The second test is a brushless direct current motor testing 3 phase axial flux construction 2 stator 1 rotor produces a rotational speed of 855.5 RPM to 2551 RPM and a torque of 0.1285 Nm to 0.1412 Nm. The third test is testing a brushless direct current motor 3 phase axial flux construction 3 stator 2 rotor produces a motor rotation speed of 350.2 RPM to 1411 RPM and a torque of 0.4506 Nm to 0.618 RPM. The fourth test is testing a brushless direct current motor 3 phase axial flux 3 stators 2 rotors star and delta connection. The delta connection produces a rotating speed of 350.2 RPM to 1411 RPM and a torque of 0.4506 Nm to 0.618 Nm. While the delta connection produces a rotational speed of 185.6 RPM to 772.1 RPM and a torque of 0.7782 Nm to 1.3136 Nm. The fifth test is testing a brushless direct current motor 3 phase axial flux 3 stator 2 roto star and delta connected with a load. The star connection produces a rotating speed of 112.8 RPM to 280 RPM, a torque of 0.4139 Nm to 0.9369 Nm, and efficiency of 0.0127% to 0.3519%. While the delta connection produces a rotating speed of 255 RPM to 422.7 RPM, a torque of 1.4531 Nm to 1.7291 Nm, and efficiency of 0.000044675% to 0.000087577%. The addition of the number of rotors affects the torque produced with a very high torque value, this is based on the construction data of 3 stators 2 rotors with a torque value of 0.618 Nm compared to the construction torque value of 2 stator 1 rotors of 0.1412 Nm. The addition of the number of stators affects the rotational speed of the resulting motor where the value is greater, this is evident in the construction data of 2 stators 1 rotor motor rotational speed of 2551 RPM compared to the construction of 1 rotor 1 stator which is 1940 RPM. The addition of the number of stators and rotors will affect the rotational speed of the motor, where the resulting value is getting lower or smaller. It also affects current, voltage, power, and torque, where the three parameters increase or the value gets bigger. The best performance of brushless direct current motor 3 phase axial flux 3 stator 2 rotors between star and delta connection, the performance is better when connected to star because the rotational speed is higher. The performance of a brushless direct current motor 3 phase axial flux 3 stator 2 rotor when switching between star and delta connections, its performance is better when star connected because of the higher efficiency value.
