Description
- 15 W compact sensorless brushless DC motor
- Stable 2500 RPM no-load speed with 5% accuracy
- Low no-load current < 0.3 A for energy-efficient performance
- Ball bearing construction for 3000-hour service life
- Suitable for medical equipment and compact airflow systems
The BL4812-087A Brushless DC Motor is a 48 mm diameter, 15 W sensorless BLDC motor designed for compact equipment requiring stable and precise airflow or rotational performance.
With 2500 RPM no-load speed (5%), <0.3 A no-load current, and sensorless drive, it provides smooth, low-noise operation while reducing system complexity.
Its ball-bearing structure, 3000-hour lifecycle, and moderate 48 114 41.7 mm size make it ideal for medical devices, compact ventilation modules, and embedded cooling systems.
