There are three coils on the stator of the BLDC motor, each coil has two wires, and there are six lead wires in the motor. In fact, due to internal wiring, usually only three wires are needed, but one more than the previously mentioned DC motor (brush motor). Purely by connecting the positive and negative poles of the battery will not move.

As for how to run the BLDC motor, it will be explained in the second part of this series. This time we are going to focus on the advantages of BLDC motors. The first feature of BLDC motors is "high efficiency". It can control its turning force (torque) to always maintain the maximum value. In the case of a DC motor (brush motor), the maximum torque can only be maintained for a moment during rotation, and cannot always be maintained at the maximum value. If a DC motor (brush motor) wants to get the same torque as a BLDC motor, it can only increase its magnet. This is why a small BLDC motor can also give out great power. The second feature is "good control", which is related to the first.
