12V BLDC Server Fan with Sensorless Sinusoidal Control
Description
This is a reference design for a 12V 3-phase brushless DC fan: intended for server cooling applications. It is based on a single IC controller: the DRV10975: which drives sensorless BLDC motors with sinusoidal current that minimizes acoustic noise and torque ripple. The design requires no microcontroller or firmware: enabling a faster time to market.
Features
- Cost-optimized and high performance.Runs Sunon's standard off the shelf BLDC fan (SG40281B1): and PCB matches the form factor.Supports 20k RPM with 12V 7W input.Sinusoidal sensor-less control at 25kHz for minimized torque ripple and audible noise.Flexible support across other fan models with its tunable register settings.Design has been built and proven.
Applications
- Spectrometer
- Automotive test
- Oven
- DC-input BLDC motor drive
- DC fast charging station
- Air conditioner indoor unit
- Professional video camera
- Wireless EV charging station
- Cooking top
- DC wallbox charger
