Magnet rotation "is the most prominent feature of brushless DC motors, which utilizes the magnetic field generated by the current in the stator coil to rotate the rotor with magnets. The switching of current is controlled by sensors and integrated circuits to control the outer rotor type (with the rotating part outside the stator). Advantages: Strong torque can be obtained. Insufficient speed stability during constant speed rotation. Large rotor volume (low sensitivity). Due to the rotating part being located outside the stator, safety measures need to be considered.
Advantages of the inner rotor type (with the rotating part inside the stator): the rotor has a small volume, high sensitivity, and the coil is located on the outside of the rotor, with good heat dissipation performance. However, it is difficult to obtain strong torque due to the influence of centrifugal force, which can cause damage to the magnet.
