Application of Micromotor in Automobile

2020-04-16 11:47

Micro-motors or simply micro-motors are used in automobiles. Its function is to convert electrical energy into mechanical energy, thereby driving the equipment to run and starting the car.

Generally speaking, in addition to the starter that starts the engine, the electric motor of other components is also a micromotor, so it has become an indispensable component in the car and is the source of power for other components.

The micromotors in the car are all miniaturized DC motors, and their total power is under 100 watts. Due to the particularity of automobile operation and the bad environment, the requirements for automobile micro-motors are getting higher and higher, and the quality is getting better and better. Determine the mass of the motor. In addition to the design structure and processing technology, it also includes the magnetic material of the movement.

Currently, the magnetic material of the movement mainly uses permanent magnetic materials containing rare elements, which are mainly composed of iron, boron, neodymium, etc. No matter what shape it is processed into, it has strong magnetism. Its magnetic properties are 2 to 10 times higher than ordinary magnets. If this material is used to make electric motors, the efficiency will be greatly improved, and its light weight will also reduce the weight of the entire vehicle and increase the carrying capacity.

Although the function of the automobile micro-motor is very important, it cannot be used alone. It must be used in combination with the conversion mechanism to play its maximum role and achieve the maximum effect. The conversion mechanism includes a wiper motor servo mechanism, a central control door lock, etc. These are commonly used switching mechanisms.

Nowadays, the use of automotive micro-motors in automobiles is increasing. Micro motors are used in ABS systems, electronically controlled suspension systems, electronically controlled power steering and electronic throttles, which also show their importance. So we can no longer ignore it.
