Micro motors are used in many places in automobiles. With the popularity of electric vehicles, various configurations of automobiles have also improved, and micro motors have been used in more applications. So let’s talk about where micromotors are used in cars.

1. Wipers

The wiper of the windshield glass is the most common example of the use of micromotors. There is a wiper on every car, and its up and down movement is caused by the drive of the micromotor. Some cars are also equipped with rear wipers. In addition to In addition to driving the wiper, a micromotor is also needed to transport the glass cleaner;

2. Blower

This is also found in every car. Relatively speaking, the higher the configuration, the more blowers on the car. For example, the blowers on the seats are also driven by micromotors.

3. Electric seats

A reduction motor is used to adjust the front and rear, up and down, waist, etc. of the seat through motor drive.

4. Electric windows/sunroof

Compared with the old hand-cranked car windows, electric windows are very common nowadays. There is a micromotor under each window to drive the car windows up and down;

In addition to the above categories, the electric trunk, electronic handbrake, convertible top, automatic door, intelligent telescopic reversing mirror, and electric tail wing on the car all need to be driven by micromotors. It may be understood that they need to use electricity. Micro motors are used in all driving places.

Nowadays, motors have gradually replaced belt-type mechanical parts, typically including fans, fuel pumps, refrigeration compressors, etc. The use of motors to drive is more environmentally friendly and energy-saving than traditional belt rollers, and the location design is more flexible and will not be affected by Each belt pulley is limited. At present, most vehicle motors use the automotive 12V standard. Brushed DC motors are used much more in cars than brushless DC motors. Of course, brushless DC motors are also used in There are obvious advantages in power density, such as wipers, air conditioners, etc. These devices tend to run for a long time, and brushed DC motors, such as power windows and power seats, which have short and instantaneous running times, have more advantages. . Generally speaking, equipment that runs for a long time uses a brushless DC motor, while equipment that runs for a short time and runs instantaneously uses a brushed DC motor.
