The working principle of brushless DC geared motor

Brushless DC geared motor is based on a brushless DC motor with a matching gear reducer. So what is the working principle of brushless DC geared motor? Here is the explanation for you

Brushless DC geared motor in order to achieve brushless commutation of DC motor, generally put the armature winding on the stator and the permanent magnet magnet on the rotor, which is just the opposite of the structure of traditional permanent magnet DC geared motor, but there is no brush commutation, and the general DC power supply to each winding of the stator can only produce a fixed broken field, which cannot interact with the permanent magnetic field generated by the rotor magnet in motion to It cannot interact with the permanent magnetic field generated by the rotor magnets in motion to produce continuous single direction torque, and cannot drive the rotor to rotate continuously. The brushless DC gear motor replaces the brush and phase changer of the brush DC gear motor with position detector and electronic phase change circuit, i.e., electronic phase change replaces mechanical phase change, and the rotor position signal is provided by the position sensor, and after logic processing by the controller, the electronic phase change circuit is controlled to change the phase so that the armature magnetic field generated by the stator winding and The armature magnetic field generated by the stator winding interacts with the permanent magnetic field generated by the rotor magnets to produce continuous torque and ensure continuous operation of the gear motor.
