Smart Control: Embrace Silent Driving Joy!

Topband Motor’s 36mm DC brushless inner rotor motor, designed for automotive electric doors, delivers low-speed high-torque output with Hall feedback, low noise, and high reliability. It provides smooth, powerful support for electric doors, enhancing vehicle premium feel and technology while offering a comfortable, convenient experience across luxury sedans, SUVs, commercial and new energy vehicles.

Scene Introduction

With intelligence, technology and convenience, automotive electric automatic doors are rapidly becoming a popular configuration for modern cars, widely used in high-end commercial vehicles, family SUVs and sedans. It provides convenience for family travel, especially friendly to young people, and at the same time enhances the grade of business reception, highlights the sense of technology and luxury of the vehicle, and greatly optimizes the user's actual use experience.

The automatic push-open car door is driven by motorized hinge and linkage mechanism, which transforms the rotary motion into outward push-open or inward close action of the door, and with the help of sensors to monitor the position and obstacles in real time, to ensure the accurate, smooth and safe action. Intelligent control supports a variety of operating modes and is both quiet and durable, which not only enhances convenience and a sense of technology, but is also particularly suitable for high-end models and narrow space scenarios, fully demonstrating the humanization and innovation of modern automotive design.

Pain point analysis

With the upgrading of automotive automatic door motors from brushed to brushless technology, there are still problems in actual use, which not only affect the user experience, but also have a direct impact on the market competitiveness of the product.

1. Instantaneous motor starting power, insufficient torque

2. Noisy and obvious vibration during operation

3. Unsteady opening and closing of the door, difficult to operate manually

4. Motor load is too large, easy to overheat

Product Advantages

Topband Motor has been deeply engaged in the application of automotive components for nearly two decades, and has launched a new design solution for automotive electric door motors, which has the following significant advantages:

1.Low cogging torque

By optimizing the stator and rotor design and adjusting the distribution of the air gap, it effectively reduces the vibration and noise of the motor when it is running, and improves the smoothness of the door opening and closing. This provides users with a quiet and comfortable experience, and also improves the motor's operating efficiency and reliability.

2.High torque

High torque output ensures fast and smooth door opening and closing, and maintains strong power even under low temperature or high load conditions. At the same time, the optimized heat dissipation design effectively reduces the operating temperature, prolongs the life of the motor and reduces maintenance costs.

3.Highly compatible

can be equipped with an advanced control system to accurately control the real-time opening and position status of the door, ensuring smooth and quiet opening and closing. It is also equipped with a variety of safety devices to protect the user's safety in all aspects.
