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).
