Brushless motor structure -

Structure of brushless motors are very many, each are not identical, it ultimately consist of rotor, stator and motor control part of the brushless motor system, the rotor is composed of permanent magnets and so on, the stator is composed of coil winding and iron core, motor control by the change and check phase component and the composition of the brushless motor controller. Rotor is divided into outer rotor and rotor, rotor with multipole magnetic steel block or annular magnets, on the stator winding, position detecting element at a specific location on the stator and the controller to cooperate with each other, normal control motor commutation, now most with hall element, also have other ways to control commutation. Don't consider electronic commutation part, the structure of the brushless motor is very simple, can be compared with ac synchronous motor.
