The SF-266 (266 Motor SF-266SH-10340) is a compact 12V brushed DC motor primarily designed for use in automotive HVAC systems, specifically as a drive unit for HVAC actuators (air flap actuators / air door actuators).
It is typically integrated into automotive air conditioning control systems and works with a gear reduction mechanism to precisely adjust the position of air distribution flaps (such as blend doors and mode doors), enabling accurate control of cabin temperature and airflow direction.
This motor is not designed for high-speed output. Instead, it is engineered for intermittent operation, low-speed stable performance, and long-cycle durability in automotive control environments.
The SF-266 adopts a standard brushed DC motor architecture, where current reversal is achieved through brushes and a commutator, enabling continuous rotor rotation.
In HVAC actuator systems, the motor is typically combined with a gear reduction assembly:
This configuration makes the motor highly suitable for short-stroke, frequent, and intermittent control applications.
| Parameter | Description | Engineering Significance |
|---|---|---|
| Model | SF-266 / SF-266SH-10340 | HVAC actuator motor designation |
| Motor Type | Brushed DC Motor | Cost-effective, suitable for automotive open-loop control |
| Rated Voltage | 12V DC | Compatible with standard automotive electrical systems |
| Size | Approx. 21 * 26 mm class (266 structure) | Designed for compact dashboard installations |
| Operating Mode | Intermittent duty | Matches HVAC flap control behavior |
| Application | HVAC actuator / air flap system | Automotive air distribution control |
| Output Type | Gear-reduced output | Provides low-speed, high-torque motion |
The SF-266 motor is widely used in automotive HVAC actuator systems, including:
Its primary function is to precisely control flap position, enabling dynamic adjustment of cabin temperature and airflow direction.
In HVAC actuator design, the SF-266 series motor is typically selected for applications requiring:
In practical use, it is generally integrated with a gearbox, limit mechanism, and control module to form a complete actuator system.
The SF-266 / 266 Motor SF-266SH-10340 is a compact DC drive motor designed for automotive HVAC actuator systems. Its core value lies in its compact size, 12V system compatibility, and reliable performance under intermittent operating conditions.
It is not a high-speed power motor, but a purpose-built actuator drive unit optimized for automotive air conditioning flap control systems, playing a critical role in vehicle cabin comfort and climate regulation.
