In a DC brush motor, the stator is a permanent magnet and the rotor is a wound coil; the magnetism has two poles, which repel each other and attract each other.
Therefore, passing direct current through the rotor coil will allow the rotor to rotate until it reaches the position where the torque is the smallest with the stator. At this
time, due to the commutation of the brushes, the position where the torque was originally the smallest becomes the position where the torque is the largest. Finally,
over and over again, the rotor continues to rotate. .
Brushless DC does not have brushes; at the same time, in brushless DC motors, the stator is a permanent magnet and the rotor is a winding structure.
In brushless DC motors, the stator is a winding and the rotor is a permanent magnet. If the winding is still on the rotor, you have to rely on physical contact to energize
the winding, which does not solve the problem of brush aging. In the brushless DC motor, the winding exists in the stator and has three phase wires; when working, the
input and output currents are successively supplied to the three phase wires to achieve the purpose of commutation. In brushless DC, the electromagnetic force generated by the
rotor and stator is the same as that of brushed DC.
For brushless DC motors, it is not necessarily whether the stator is inside or outside. A motor with a rotor outside and a stator inside is generally
called an external rotor motor. The hub motor is a very special external rotor motor.
Brushless DC motor, why is it classified as AC motor?
This is because when we supply power to the controller of brushless DC and permanent magnet synchronous motors, we supply DC
power, so it is called brushless DC; however, after the DC power is inverted through the motor controller, it communicates with the motor. For the three connected phase lines,
the power supply type changes to AC. Only the changing phase voltage of AC can cause the current on the three phase lines of the motor to continuously reverse direction,
so the motor is classified as an AC motor.
