AI Technical Summary
Technical Problem
Existing fan controllers for ceiling fans often fail to efficiently control the speed of larger fan motors at the lowest setting, causing them to rotate slower than designed, leading to inefficiency.
Method used
A fan controller that includes a power meter circuit to determine the size of the fan motor and selectively couples it to either a first or second capacitor based on the motor's size, ensuring optimal operation at the lowest speed setting.
Benefits of technology
The controller ensures that larger fan motors operate efficiently at the lowest speed by selecting the appropriate capacitor, improving energy usage and performance.
