Motor Applications in Wing Gates

1. Component Overview

Wing gates are a common access control device in systems such as subways, office buildings, and airports. They play a crucial role in managing personnel flow efficiently. The core power unit is a brushless DC servo motor, typically paired with a high-precision harmonic reducer to ensure torque and positioning accuracy. The motor works with a driver, encoder, and sensors to achieve precise control over the wing gate's opening angle and speed. Key components include:

• Brushless DC Servo Motor: Compact, quick-response motor with high torque density, supporting frequent start-stop cycles and dynamic speed adjustments.
• Harmonic Reducer: Significantly reduces speed while maintaining extremely low backlash, ensuring smooth and stable wing gate movements.
• Encoder and Feedback Devices: Real-time monitoring of motor speed and position, enabling closed-loop control to avoid incorrect movements.
• Safety Sensor System: Infrared photoelectric sensors and pressure-sensitive devices detect the passage status and blockages, preventing injury from door jams.
• Controller and Driver Module: Integrates advanced motion control algorithms, supporting various communication protocols (EtherCAT, CANopen, etc.) for seamless integration with the access control system.
• Enclosure and Wing Gate Structure: Made of corrosion-resistant aluminum alloy and steel, designed with dustproof and waterproof features for use in complex environments.

2. Working Principle

After the access control system validates the user, the controller sends an open command to the motor. The motor quickly starts, driving the wing gate to open through the harmonic reducer. The motor and control system work together to precisely control the opening angle (typically 90° or smaller), adjusting the speed curve in real-time to ensure smooth operation without any impact. Once the gate is open, infrared and pressure sensors continuously monitor the passage. If any blockage is detected, the control system will reverse or stop the motor immediately, preventing injury. After passage, the motor gradually and accurately closes the wing gate, ensuring it locks tightly to prevent unauthorized entry. During the entire process, the motor must perform high-frequency start-stop cycles to maintain high passage efficiency during peak periods while ensuring low noise and high reliability.

3. Role of the Motor in the System

The servo motor is the heart of the wing gate system, directly affecting the equipment's performance and user experience. Its main functions include:

• High-Frequency Start-Stop Capability: Wing gates are often used in high-traffic areas, requiring frequent starts and stops. The motor must respond quickly and generate minimal heat to ensure stable long-term operation.
• Precise Position Control: The motor, along with the encoder, provides micron-level position feedback to ensure the gate's opening and closing angles are accurate, preventing mechanical impact and wear.
• High Torque Output and Smooth Motion: The harmonic reducer provides high torque output while minimizing vibration, ensuring that the gate's movement is smooth and reducing mechanical noise.
• Safety Protection Mechanisms: The motor system works closely with sensors to provide rapid power-off, reverse movement, and alarm functions, ensuring the safety of pedestrians.
• Environmental Adaptability: The motor is designed to meet an IP54 protection rating, resistant to high temperatures, moisture, dust, and corrosion, making it suitable for various complex environments.
• Energy Efficiency: The high-efficiency motor and intelligent control algorithms reduce energy consumption, extend the equipment's lifespan, and lower maintenance costs.
