Detailed explanation of the main function of an automotive armature?

　　 Automotive Armature The manufacturer stated, The armature is the part of the motor that contains the coil, and the coil's relative movement to the magnetic field. In a generator, an induced electromotive force is generated in the rotating coil under force, causing it to generate electricity. In a motor, the energized coil rotates in the magnetic field under the action of Ampere's force, causing it to rotate in the magnetic field.

　　A part of an alternating current generator or related equipment can be represented in either mechanical or electrical terms. Although distinctly separate, these two sets of terminology are often used interchangeably or include a combination of a mechanical term and an electrical term. This can cause confusion when using composite machines such as brushless AC generators, or when conversing between personnel accustomed to using differently configured machines.

　　In most generators, the field magnet is rotating and is part of the rotor, while the armature is stationary and is part of the stator. Motors and generators can be constructed with a stationary armature and rotating magnetic field or a rotating armature and stationary magnetic field. The pole shoes of permanent magnets or electromagnets, and the moving iron part of a solenoid (especially if the latter is used as a switch or relay) can also be called an armature.

　　The automotive armature's circuit equipment is simple, low-cost, and easy to operate. The disadvantages are high power loss, low efficiency, and reduced motor output. It plays a key and crucial role in the process of realizing the mutual conversion of mechanical energy and electrical energy. A square-wave self-controlled permanent magnet synchronous motor is used, with a Hall sensor replacing the carbon brush commutator, and the rotor permanent magnet material is neodymium iron boron. To our understanding, its performance has significant advantages compared to general traditional DC motors. Automotive armatures have advantages such as high efficiency, low energy consumption, low noise, long life, high reliability, servo control, stepless frequency conversion speed regulation, etc. Moreover, the brushes are removed, and the direct change is that the brushed motor will not produce sparks during operation, greatly reducing the interference of sparks on radio-controlled radio equipment. In short, an automotive armature generally refers to the part of the motor that requires an external power supply. The armature of a DC motor is the rotor, and the armature of an AC motor is the stator.

　　Automotive armatures have no brushes, greatly reducing friction during operation, resulting in smooth operation and much lower noise. This advantage is a huge support for model stability. The advantages of automotive armatures also lie in the fact that wear mainly occurs on the bearings. From a mechanical point of view, brushless motors are almost maintenance-free. Only some dust removal maintenance is needed if necessary. From a mechanical point of view, automotive armatures are almost maintenance-free motors, only requiring some dust prevention maintenance when necessary. Of course, when you use them, you can compare them up and down, and you will know the advantages compared to brushed motors, but nothing is absolute. Brushed motors have excellent low-speed torque performance and high torque characteristics. Automotive armatures are irreplaceable, but in terms of ease of use, with the reduction in the cost of automotive armatures and the development and market competition of brushless technology at home and abroad, its power system is in a stage of rapid development and popularization, which has also greatly promoted the development of model sports.
