28BL01 series Dc Brushless Motor With Planetary Gearbox nema11 small gear motor

The stator of the brushless deceleration motor is composed of permanent magnet steel. Its main function is to generate a magnetic field in the air gap of the motor. After the armature winding of the motor is energized, a reactive magnetic field is generated. The brush motor commutates through the brush, while the brushless motor The commutation is by placing the armature winding on the stator and the permanent magnet on the rotor, which is exactly the opposite of the DC brushed motor, but this can only fix the magnetic field and cannot interact with the permanent magnetic field generated by the moving rotor magnet. function, to generate a single direction of torque to drive the rotor to rotate, so the brushless motor needs to be equipped with a position sensor, a control circuit and a power logic switch in addition to the stator and the rotor to form the motor, so that the stator winding of the brushless motor during operation The generated magnetic field and the permanent magnetic field generated by the rotating rotor magnets are always kept at an electrical angle of about (π/2) rad in space.
