Modo Atuador
Multi-Position Servo Motor for Advanced HVAC Airflow Distribution
Product Overview
The Modo Atuador is a high-precision, multi-position servo motor designed to control the air distribution dampers within automotive Heating, Ventilation, and Air Conditioning (HVAC) systems. Unlike basic on/off actuators, this advanced component enables precise directional airflow control, allowing drivers and passengers to select from multiple ventilation modes—such as face-level, foot-level, defrost, or mixed airflow—based on comfort needs.
By integrating intelligent positioning logic with robust mechanical design, the Mode Actuator ensures smooth, accurate, and repeatable damper movement across various vehicle environments. It plays a pivotal role in enhancing cabin comfort, improving air circulation efficiency, and supporting modern vehicle climate control systems that prioritize user experience and energy optimization.
This actuator is engineered for use in both original equipment manufacturing (OEM) and aftermarket applications, offering reliable performance across passenger vehicles, commercial vans, and electric mobility platforms.
Key Features & Technical Advantages
- Multi-Position Control: Supports up to four distinct stop positions at 36°, 67°, 95°, and 136° ±2°, enabling precise selection of airflow direction. The adjustable angle allows customization for different HVAC duct designs.
- Step-by-Step Positioning via Pin Configuration: Utilizes a unique position pin connection system in conjunction with polarity switching to achieve discrete stopping points. Each position corresponds to a specific airflow mode, ensuring consistent and accurate operation.
- High-Torque Performance: Delivers 4 kgf·cm running torque and 12 kgf·cm locked torque, providing strong resistance against mechanical friction and maintaining stable damper positioning under load.
- Low Power Consumption: Operates efficiently at just 3W with a maximum current draw of 70mA, minimizing impact on the vehicle’s electrical system and battery life.
- Quiet Operation: With a noise level of max. 42 dB(A), it operates silently—ideal for premium cabins where acoustic comfort is essential.
- Wide Operating Temperature Range: Functions reliably from -30°C to +80°C, with storage capability up to +85°C, making it suitable for global climates and extreme conditions.
- Long Service Life: Designed for up to 500,000 operational cycles, ensuring durability even in high-frequency usage scenarios such as daily commutes or long-haul driving.
- Compact & Lightweight Design: Measures 83 × 50 × 28 mm and weighs only 94g, allowing easy integration into tight HVAC housing without compromising space or weight balance.
- Dual Voltage Compatibility: Supports both DC 12V and DC 24V power supplies, making it adaptable to a wide range of vehicle types including light commercial vehicles and heavy-duty trucks.
- Certified Quality Standards: Complies with ISO 9001 and TS16949, guaranteeing consistent quality, traceability, and compliance with automotive industry requirements.
How It Works: Intelligent Airflow Management
The Mode Actuator operates using an electrically driven rotary mechanism powered by a DC motor. Its control method combines two key inputs:
- Polarity Reversal: By switching the positive (+) and negative (-) terminals of the control wire, the actuator rotates in either clockwise (CW) or counterclockwise (CCW) direction.
- Position Pin Selection: A set of internal mechanical pins connects to external wiring terminals, defining specific stop positions. When voltage is applied, the motor turns until it reaches one of these preset angles—ensuring the damper stops at the correct airflow setting.
This dual-control approach enables linear and predictable airflow distribution, allowing for optimized air delivery across different zones of the cabin. For example:
- Face Level: Directs cool air toward the upper body
- Foot Level: Provides warm air to lower body areas
- Defrost: Channels airflow to the windshield for rapid demisting
- Mix Mode: Balances between multiple outlets for uniform temperature
Additionally, some models include potentiometer feedback or Hall-effect sensors to provide real-time position data to the HVAC control module, enabling closed-loop control and fault detection.
