Abstract: An air conditioner and a startup control method and system for an outdoor fan of the air conditioner. While in a process of charging a bootstrap capacitor in an actuator of a motor of the outdoor fan, an initial rotation state of the motor is detected in real time, and, when charging of the bootstrap capacitor is completed, startup of the motor is correspondingly controlled on the basis of the detected initial rotation state. This allows real time initial startup work state to be acquired when charging of the bootstrap capacitor is completed, thus allowing the motor to be started smoothly, increasing the success rate in starting the motor, and solving the problem of low success rate in starting the motor of an outdoor fan.

Abstract: A method and apparatus for driving motor and appliance. When a rotor of a motor rotates, a current angle of the rotor is detected at a current moment by using a Hall sensor; a back electromotive force and a phase current of the motor is detected at the current moment; a target torque coefficient is detected by using a relational model for a back electromotive force and a torque coefficient according to the back electromotive force; a current torque coefficient is detected by using a relational model for a phase current and a torque coefficient according to the detected phase current; and a compensation angle is detected according to a rotor angle compensation model and the current angle is compensated by using the compensation angle, to obtain an adjustment angle; and power supply to the motor is adjusted according to the adjustment angle by using a field orientation technology.

Abstract: The present invention is applicable to the motor field, and provides a method and apparatus for driving motor and appliance.

Abstract: One embodiment provides a method for facilitating a seller of a product to sell the product. The method includes accessing information retrieved from a search query conducted by a potential buyer for the product. The buyer information of the potential buyer is extracted form the accessed information. The buyer information includes, for example, contact and interest information of the potential buyer. Thereafter, the buyer information of the potential buyer is transmitted to a third party. In turn, a compensation for the product is received from the potential buyer, in which the compensation identifies the third party as a promoter of the product. A commission is then transferred to the third party in response to the received compensation for the product from the potential buyer.
