Brushless motor, abbreviated as BLDC, refers to a motor without carbon brushes and electric brushes. Its working principle is to control the internal rotor of the motor through an electronic speed controller to rotate. Compared to brushless motors, brushless motors have a longer lifespan, higher efficiency, and lower noise.
A brushless DC motor consists of a permanent magnet rotor, a multi pole winding stator, a position sensor, etc. Position sensing converts the current of the stator winding in a certain order according to the change in rotor position (i.e. detecting the position of the rotor magnetic poles relative to the stator winding, and generating position sensing signals at the determined position. After being processed by the signal conversion circuit, it controls the power switch circuit and switches the winding current according to a certain logical relationship). The working voltage of the stator winding is provided by an electronic switch circuit controlled by the position sensor output.
There are three types of sensors: magnetic sensitive, photoelectric, and electromagnetic.
A brushless DC motor using a magnetic sensitive position sensor has magnetic sensor components (such as Hall elements, magnetic diodes, magnetic sensitive transistors, magnetic resistors, or specialized integrated circuits) installed on the stator assembly to detect magnetic field changes generated by the rotation of permanent magnets and rotors.
A brushless DC motor using photoelectric position sensors is equipped with photoelectric sensor components at certain positions on the stator assembly, a light shielding plate is installed on the rotor, and the light source is a light-emitting diode or a small light bulb. When the rotor rotates, due to the effect of the shading plate, the photosensitive components on the stator will intermittently generate pulse signals at a certain frequency.
The brushless DC motor using electromagnetic position sensors is equipped with electromagnetic sensor components (such as coupling transformers, proximity switches, LC resonant circuits, etc.) installed on the stator assembly. When the position of the permanent magnet rotor changes, the electromagnetic effect will cause the electromagnetic sensor to generate high-frequency modulation signals (whose amplitude changes with the rotor position).
