Unified Speed Control Platform for BLDC Ceiling Fans

The market for BLDC ceiling fans is experiencing significant growth, with consumers increasingly expecting diverse speed control options. This unified platform meets this demand by integrating three control methods (advanced mobile apps, standard IR remotes, and conventional wall mount regulators) into a single design. This comprehensive approach offers enhanced flexibility for consumers while enabling manufacturers to cover a wider market segment with a unified system. By consolidating multiple control options, the platform significantly reduces inventory requirements and bill of materials (BOM) costs, providing a competitive edge in the evolving BLDC ceiling fan market.

System Benefits:

• Multiple speed regulation options reduce dependency on specific devices.
• Adopts critical conduction mode PFC to achieve a power factor >0.9.
• A wider operation range allows the fan to run at a single speed with lower motor losses due to high voltage winding.
• Can be integrated into any existing motor control design to support various speed control solutions by sensing wider line operating parameters and providing speed commands to the motor controller.
• Closed-loop speed control and error optimization maintain consistent speed.
