Application of Micro Motors in Cars
With the developing of car technology, micro motor’s application scope is evolving. For instance, in smart cabin, automatic driving system and battery management system of electric cars, the application of micro motor is becoming much more popular.
Automotive micro motor is the motor that are compact in size, has low capacity, and delivers an output power of less than several hundred watts. As an important component of car, micro motor usually meets the car requirements of power, precise control and energy saving. And it has the characteristics of high torque, low noise, small size, light weight, convenient and constant speed.
Automotive micro motor is commonly used in car’s engine, chassis. It is primarily used in systems such as brake assist, power steering, seat adjustment, windshield wipers, and air conditioning control. Below are brief descriptions of several typical application scenarios:
Smart Cabin Motor
Automotive intelligence has become a key consideration for consumers. As the carrier of automotive smart technology, the intelligent cabin integrates technologies and products such as displays, interaction systems, operating systems, and chips, poised to lead the automotive industry into the next phase of intelligent transformation. As the driving mechanism, automotive micro motor control systems will continue to play a significant role in enabling the movement of electronic components within the intelligent cabin.
Seat Motor
Micro motors enable adjustable seat angles and massage functions, effectively alleviating driver’s fatigue and delivering a comfortable driving experience.
Electric seats utilize motor’s drive transmission mechanisms and actuators, allowing adjustment of seat position, height, and backrest angle. Premium models can offer adjustable thigh support and lumbar support, providing drivers and passengers with comfort.
CID Motor
As a vital component of modern automotive interiors, the CID is typically positioned at the center of the dashboard for easy viewing and operation by the driver and front passengers. To enable drivers to read information more directly and interact conveniently, the position and angle of screen require flexible adjustment. Consequently, two motion mechanisms for CID were designed: one is an electrically driven car screen that slides horizontally along a track; the other is a display that vertically lifts and lowers via an electric drive unit.
Despite differing movement directions, their technical principles are highly consistent, involving motor drives, electronic control systems, mechanical structures, sensors, and other components. The core is the motor that providing driving power, which connected via cables to the car power system.
With the development of intelligent driving technology, the volume of information that drivers need to assess and receive is growing. Traditional display technologies are clearly inadequate, making the installation of smart screens imperative.
