What is the role of the micro DC motor position sensor?

By applying DC voltage, the micro motor transforms electrical energy into mechanical energy. High speed rotation occurs in the micromotor. The spinning speed increases with increasing voltage input. The micromotor will make use of the position Hall sensor. How does it work? I'll go into further depth below.

In order to control the commutation of the stator winding, the position sensor in the micromotor measures the position of the rotor magnetic pole, provides the circuit switch with commutation information, converts the position signal of the magnetic pole of the rotor magnetic steel into an electrical signal. Common sensors include photoelectric, magnetic, and electromagnetic. One of the most widely utilized types of sensors in micromotors is electromagnetic. The photoelectric effect is used in the production of photoelectric sensors. The usage of magnetic sensors is also widespread. The magnetoresistance effect and the Hall effect are the fundamental concepts. Later integrated circuits or hall elements, etc.

The carbon brush motor has a permanent magnet stator, a commutator fitted on the rotor, a pair of electric brushes or carbon brushes fixed to the back cover, and a rotor made of a coil winding connected to the output shaft. It is referred to as a carbon brush motor. Although brushless motors do not require commutators or brushes, their speed management is expensive and difficult.
