DC Sectional Door Control Box

FOC Brushless DC Control System for Industrial Sectional Doors

This DC Sectional Door Control Box is developed by Wuxi Ruisida Electric. It is designed for industrial sectional door systems using brushless DC motors.

The system adopts field-oriented control (FOC) technology to achieve precise torque and speed regulation of the motor under closed-loop control conditions.

Compared with traditional AC motor drive systems, brushless DC solutions provide higher efficiency, lower acoustic noise, and improved operational stability under variable load conditions.

The system supports motors in the 400 W to 1500 W range at 220 V.

Position Control and Limit Recovery System

The control box integrates an external multi-turn absolute encoder for position feedback.

The encoder maintains accurate position memory and ensures that door travel limits are preserved during power loss or manual operation.

The system automatically restores position reference after power recovery, eliminating the need for manual limit resetting.

Soft start and soft stop control reduce mechanical impact on the door structure, improving system stability and service life.

System Protection and Human-Machine Interface

The control system includes multiple protection functions, including:

Stall protection
Over-voltage protection
Over-temperature protection
Overload protection

An LCD interface provides clear menu navigation and system parameter configuration in simplified operation structure.

The system supports integration with dock levelers and external automation equipment for coordinated operation in logistics environments.

Each unit undergoes full functional testing and aging verification before shipment to ensure stable industrial performance.

High-Efficiency Industrial Door Automation Solution

This DC Sectional Door Control Box is suitable for industrial sectional doors, logistics passages, and factory environments requiring efficient and low-noise operation.

We provide a 3-year warranty for the complete unit and long-term technical support. For international customers, remote commissioning, troubleshooting, and integration support are available.

Samples can be provided for evaluation before bulk orders. Custom control logic and interface configuration are supported upon request.

This DC Sectional Door Control Box provides high-efficiency motor control, improved system responsiveness, and stable operation for modern industrial door applications.
