The hidden core in the wave of automotive intelligence, the Chinese market size is expected to exceed 119.5 billion yuan by 2025

With the acceleration of the electrification and intelligence process of automobiles, the Window Lift Motor, which is the "heart" of the window lift system, is upgrading from a basic functional component to a core node of the intelligent cockpit. The latest industry data shows that the market size of automotive electric window motors in China reached 115.08 billion yuan in 2024, with a year-on-year growth of 9.2%. It is expected to further rise to 119.535 billion yuan in 2025, continuing to demonstrate stable growth resilience. ​

 

From mechanical drive to intelligent hubs, technological iteration reshapes product value

The core function of the car window lift motor is to convert electrical energy into mechanical energy and achieve the linear lifting of the car window glass through the transmission mechanism. Its working principle is based on the precise control of the motor's rotational motion - when the driver triggers the control command, the motor completes the motion form conversion through transmission components such as the gearbox, driving the car window to run smoothly. This process imposes strict requirements on the motor's accuracy and reliability. Nowadays, this traditional component is undergoing two major technological changes:

In terms of product form, brushless DC motors (BLDC) are accelerating their replacement of traditional brushed motors. Compared with brushed motors, brushless solutions achieve precise rotor position detection and electronic commutation through Hall sensors, extending the lifespan by more than twice, reducing operating noise to below 38 decibels, and significantly improving energy efficiency. Data shows that the installation rate of brushless motors in newly launched electric vehicle models reached 30% in 2024, and it is expected to exceed 38% in 2025. The penetration rate in mid-to-high-end models even exceeds 45%. The brushless motor solutions independently developed by enterprises such as Changzhou BYD Auto Parts Co., Ltd. have been applied in batches in many mainstream new energy vehicle models, significantly enhancing the driving and riding experience with their quiet feature. ​

 

In terms of functional integration, motors are upgrading from single actuating components to intelligent control systems. The integrated solution that integrates CAN communication modules, active anti-pinch algorithms and OTA upgrade capabilities has become the focus of research and development. Foreign object identification is achieved through motor speed changes and current monitoring, and the anti-pinch accuracy can reach the millimeter level. The intelligent window control system developed by Ningbo Joyson Electronics has been equipped on models such as BYD Han and Li Auto L series. It deeply integrates the motor with sensors and controllers, achieving multi-speed adjustment and self-diagnosis of faults.
