Operational principle
Brushed DC motors use semiconductor switching devices to achieve electronic commutation, which replaces traditional contact commutators and brushes with electronic switching devices. It has the advantages of high reliability, no commutation sparks, and low mechanical noise, and is widely used in high-end recording consoles, video recorders, electronic instruments, and automated office equipment.
A brushless DC motor is composed of a permanent magnet rotor, a multipole winding stator, a position sensor, etc. Position sensing commutates the current of the stator winding in a certain order according to the changes in rotor position (that is, detects the position of the rotor magnetic pole relative to the stator winding, and generates a position sensing signal at the determined position. After being processed by the signal conversion circuit, the power switch circuit is controlled to switch 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 position sensors: magnetic sensitive, photoelectric, and electromagnetic.
Brushless DC motors using magnetic sensitive position sensors have magnetic sensor components (such as Hall elements, magnetic diodes, magnetic transistor, magnetic resistors, or specialized integrated circuits) installed on the stator components to detect changes in the magnetic field 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 shield is installed on the rotor, and the light source is a light-emitting diode or small light bulb. When the rotor rotates, the photosensitive components on the stator will intermittently generate pulse signals at a certain frequency due to the effect of the shading plate.
A 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).
