Source | Intelligent Vehicle Club
With the rapid development of new energy vehicles (NEVs), the automotive industry is moving toward electrification and intelligence, bringing drivers and passengers a safer, more convenient, and more comfortable travel experience. In this transformation, micro motor actuators have become a key technology component, driving innovation and upgrades across modern vehicles. From body control to power systems, from smart cockpits to intelligent chassis, micro motor actuators are enhancing vehicle performance, improving user experience, and shaping the future of intelligent mobility.
This article explores what micro motor actuators are, their applications, features, and future development trends.
A micro motor actuator is a compact electromechanical device that integrates a micro DC motor, gearbox, and control circuit. It receives commands from the vehicle’s controller and converts them into mechanical actions or physical effects, enabling precise control of different electrical and mechanical systems.
Automotive micro motor actuators come in various types, designed to meet the needs of different systems and components across the vehicle.
Micro motor actuators are essential for modern vehicles, enabling automation, safety, and comfort. They are widely applied in four main areas: body control, smart cockpit, intelligent chassis, and power systems.
Hidden door handles: Control automatic extension and retraction of door handles.
Power tailgate: Enable smooth automatic opening and closing of the trunk.
Electronic mirror adjusters: Allow precise adjustment of side and rearview mirrors.
Adaptive lighting systems: Adjust headlight brightness and angle based on driving conditions.
Electric seat adjustment: Control seat height, tilt, and position for comfort.
HVAC air flap control: Regulate airflow and cabin temperature precisely.
Rotating center console screen: Drive screen rotation for flexible interaction.
Roof-mounted display: Control lifting and flipping for entertainment systems.
Electronic parking brake (EPB): Automate parking brake engagement and release.
Electric water pumps: Provide efficient and precise cooling system control, improving engine performance.
Through these applications, micro motor actuators significantly improve comfort, safety, and automation, making vehicles smarter and more user-friendly.
