Two control inputs let one motor platform serve different appliance main boards. Speed feedback reports actual rotor speed, so the appliance can hold a target airflow as filters load or duct pressure changes.
With 48 W and 3000 rpm available in a compact frame, this model suits air conditioners, air purifiers, air curtains and ventilation units that need more pressure than a 15–24 W motor can deliver.
Key features
- Dual speed inputs: 5 V analog and PWM on one motor
- Closed-loop control from built-in speed feedback
- 48 W / 3000 rpm in a compact frame
- No external driver; shorter circuit development
- Low operating noise at household appliance levels
- Suitable for air conditioner and air curtain duty
Typical applications
