Our company has its own brushless PM motor factory, which has been widely applied in the field of permanent magnet DC brushless motor in the market, such as household appliances, medical equipment, industrial equipment, power tools, etc., with different applications in each field.Then why the brushless motor market demand so large?Now let's introduce the principle of brushless motor.
Permanent magnet brushless dc motor stator is composed of permanent magnet steel, its main role is in the motor air gap magnetic field, after electrify motor armature winding respond to magnetic fields, the permanent magnet is a dc motor through the brush commutation, and brushless motor commutator is through the armature winding on the stator, permanent magnets on the rotor, just opposite of a dc motor, but only such fixed magnetic field, but not with the movement of the rotor magnet steel produced by permanent magnet magnetic field interaction, to produce a single direction of torque to drive the rotor rotation, so in addition to the brushless motor stator and rotor of motor,Position sensors, control circuits, and power logic switches are also required so that the permanent magnet DC brushless motor's magnetic field generated by the stator windings during operation and the permanent magnet field generated by the rotating rotor magnetic steel remains at an electrical Angle of approximately (/2 rad) in space at all times.
