The function of the motor is to convert electrical energy into mechanical energy and drive the equipment to operate. In the car, except for the starter that starts the engine, the other motors distributed in various places on the car are micro motors.
In the past, automotive micromotors were only used as power sources for wiper, windshield washers, electric oil pumps, automatic antennas, etc., and the number was relatively small. Nowadays, the car is focused on passenger comfort and automatic maneuverability, and the micro motor has become an indispensable part of modern cars. Some cars are equipped with more than 20 micro-motors. The movable equipment can be used as a power source, whether it is a circular motion or a lateral swing, or a linear movement. For example, the positional movement of the power seat cushion, the change in the angle of the backrest and the headrest, the swing of the mirror, the washing of the headlights, the opening and closing of the glass window, the manipulation of the electric door lock, the rotation of the water tank cooling fan, and the like.
Automotive micro-motors, as the name implies, are miniaturized DC motors with powers typically below 100 watts. Due to the special requirements of the car operation and the harshness of the environment, the user's requirements for the automotive micro-motor are demanding. For the motor, in addition to the design and processing technology, the quality of the motor lies in the magnetic material of the movement. At present, the new motor used in the car uses a permanent magnet material containing rare elements. Its main components are iron, boron, bismuth, etc. Its magical point lies in its strong magnetism. No matter what shape it is processed, its magnetic properties are better than ordinary ones. The ferromagnetic material is 2 to 10 times stronger, which means that the motor made of this permanent magnet material has large power, small size, light weight and high efficiency. When the micro motor is used in large quantities in the vehicle, the weight of the whole vehicle will be relatively reduced. Is equal to improving the carrying capacity. Roger Smith, former president of General Motors, once said that the automotive industry is now inseparable from electromagnetic materials. For industries using magnetic materials, electromagnetic materials are as important as semiconductor materials in the electronics industry. Every major breakthrough can change our lives.
The responsibility of the car's micro-motors is to drive the movement of the equipment, so it is usually accompanied by a set of changing mechanisms for deceleration and redirection. For example, the servo motor of the wiper motor adopts the form of worm gear transmission to decelerate and change the direction of the electric shaft; the motor of the central control door lock adopts the form of rack and pinion transmission, which decelerates and changes the rotation to a linear movement. These forms are the more commonly used transformation mechanisms.
The use of modern car micro-motors is getting bigger and bigger. Micro-motors are used in some car ABS systems, electronically controlled suspension systems, electronically controlled power steering machines and electronic throttles. With the development of automotive electronics, micro-motors are becoming more and more important.
