    Abstract: A driving controller uses with a ceiling fan, which has a brushless motor. The driving controller including: a microprocessor unit having control programs and ROM units. The ROM units save the departure parameter data of the brushless motor inside. The microprocessor can read a designate departure parameter from the ROM units and loads it into the control programs. A signal receiving unit connects with the microprocessor. A hardware setting unit connects with the microprocessor. A driving circuit connects with the microprocessor and the brushless motor of the ceiling fan. A feedback circuit connects with the microprocessor and the driving circuit. The feedback circuit can detect the amperage or the voltage of the driving circuit and transmits a feedback to the microprocessor. A power input unit connects with the signal receiving unit and a circuit with rectifier and filter function.
