TEMP III 제어 액추에이터
Precision Temperature Regulation Servo Motor for Volkswagen and European Vehicle HVAC Systems
Product Overview
The TEMP III 제어 액추에이터 is a high-performance, electronically controlled servo motor specifically designed to regulate the temperature blend damper in automotive Heating, Ventilation, and Air Conditioning (HVAC) systems. Widely used in Volkswagen (VW) vehicles and other European makes such as Audi, Seat, and Skoda, this actuator enables precise, continuous adjustment of cabin temperature by modulating the mix between hot and cold air streams.
Unlike basic mechanical or on/off actuators, the TEMP III features an advanced polarity-switching control mechanism combined with real-time position feedback, allowing the HVAC system to maintain consistent thermal comfort across varying environmental conditions. Its compact design, reliable operation, and OEM compatibility make it a critical component in modern vehicle climate control architectures.
This actuator is especially valued in premium and mid-range vehicles where accurate temperature regulation, low noise operation, and long-term durability are essential for occupant comfort and system efficiency.
Key Features & Technical Advantages
- Continuous Temperature Adjustment via Polarity Switching:
The TEMP III actuator operates by reversing the polarity of the power supply wires (+/-), which drives the motor to rotate the temperature damper smoothly through its full range. This allows for fine-tuned control over cabin warmth and cooling, enabling seamless transitions between different temperature settings without abrupt changes. - Integrated Position Feedback System:
Equipped with a potentiometer or Hall-effect sensor, the actuator provides real-time feedback on damper position to the HVAC ECU. This closed-loop control ensures accuracy, prevents over-travel, and enhances system stability—critical for maintaining consistent climate performance. - Adjustable Rotation Angle:
Standard rotation angle is 90° ±2°, but can be customized to meet specific OEM requirements. This flexibility supports integration into various HVAC housing designs and duct configurations. - High Torque & Mechanical Strength:
Delivers 3 kgf·cm running torque and up to 15 kgf·cm locked torque, ensuring robust operation even under mechanical resistance from dampers or internal friction. The high locked torque also helps maintain position during sudden vibrations or impacts. - Low Power Consumption:
Operates efficiently at just 3W with a maximum current draw of 100mA, minimizing load on the vehicle’s electrical system and supporting energy efficiency goals. - Quiet Operation:
With a noise level of max. 43 dB(A), it operates silently—ideal for premium interiors where acoustic comfort is a priority. - Wide Operating Temperature Range:
Functions reliably in extreme environments from -30°C to +80°C, with storage capability up to +85°C, making it suitable for global markets and all seasonal conditions. - Extended Service Life:
Designed for up to 200,000 operational cycles, ensuring long-term reliability and reduced maintenance costs—especially important in high-use vehicles. - Compact & Lightweight Design:
Measures 83.5 × 59 × 28 mm and weighs only 90g, allowing easy installation in tight HVAC compartments without compromising space or weight balance. - Molded Electrical Connection:
Features a molded wire harness connection for enhanced durability, moisture resistance, and secure electrical contact—reducing the risk of corrosion or signal loss. - OEM-Grade Quality & Certification:
Complies with ISO 9001 and TS16949 standards, ensuring strict quality control, traceability, and compliance with international automotive manufacturing norms.
How It Works: Smart Climate Control Integration
The TEMP III Actuator operates using a DC motor-driven rotary mechanism connected to the temperature blend damper inside the HVAC unit. When the driver adjusts the temperature setting on the climate control panel, the HVAC ECU sends a control signal by reversing the polarity of the power supply:
- Positive Polarity (+) → Rotates the damper in one direction (e.g., toward hot air)
- Negative Polarity (-) → Rotates in the opposite direction (e.g., toward cold air)
As the damper moves, the internal position sensor continuously monitors its angle and sends feedback to the ECU. This enables the system to:
- Accurately determine the current temperature setting
- Detect faults such as jammed dampers or stalled motors
- Maintain consistent airflow mixing for optimal thermal comfort
This intelligent control loop ensures that the cabin temperature remains stable, even when external conditions change rapidly—such as during stop-and-go traffic or exposure to direct sunlight.
