Motor Applications in Facial Recognition Access Systems
Intelligent entry control driven by precision motor technology
1. Component Overview
Facial recognition access systems consist of several core components:
Recognition & Control Module: Includes camera, infrared light, image processor, and AI algorithms to capture and verify facial features.
Passage Mechanism: Sliding doors, swing arms, flaps, or rotating bars define the passage method and turnstile type.
Motor Drive System: Brushless DC, stepper, or servo motors with gearboxes drive the doors and arms for physical motion execution.
Detection & Safety: Infrared beams, sensors, anti-pinch radar, and safety curtains ensure user safety during passage.
Controller & Communication: CPU with drive ICs and communication interfaces for access rights, logging, and remote control.
Power & Backup: Stable supply with lithium batteries or UPS ensures emergency operation and safety unlock on power failure.
2. Working Principle
Facial access control systems follow a "recognize—decide—execute—feedback" closed-loop mechanism:
Upon user approach, the camera activates, captures facial data, and verifies identity via local/cloud algorithms.
Once verified, the controller triggers the motor to actuate the gate for opening.
Sensors monitor passage; the system triggers closing after the user passes safely.
On failure, tailgating, or timeout, the system halts entry and activates alerts or locks.
Motor feedback and closed-loop control ensure responsive, safe, and accurate movement throughout.
3. Motor Roles
Motors serve as the core actuator for gate movement with the following functions:
Primary Motion Driver: Directly opens/closes doors, flaps, or arms upon verification.
Precision Control: Encoders or Hall sensors ensure accurate positioning for each motion.
Responsive Dynamics: High-performance motors support fast start-stop, torque feedback, and smooth movement during high-frequency use.
Enhanced Safety: Integration with sensors enables anti-pinch, soft-start, reverse on obstruction, and controlled braking.
Silent & Efficient: BLDC motors provide low noise and high energy efficiency for quiet environments.
Smart Management: Intelligent motors with MODBUS/CANopen support remote control, self-diagnostics, and real-time alerts.
4. Custom Motor Solutions
To meet varying structures and usage needs, we offer targeted motor solutions for facial access control systems:
By Mechanism Type:
- Sliding doors: Low-speed, high-torque BLDC motors (GPG-BL32) with worm gear reducers for smooth office or residential use.
- Swing barriers: Compact mid-torque servo motors (GPG-GMS) for high-frequency areas like subway gates or factory exits.
- Flap gates: Miniature BLDC motors (GPG-BL28) with multi-speed and brake control for synchronized dual-wing motion in commercial settings.
Integrated System Support:
- Precision reducers (planetary or worm gear) for quiet and stable transmission
- High-res magnetic encoders (12–17 bit) for stop-start and position accuracy
- Interfaces (TTL, RS485, CANopen) for broad controller compatibility
