The ship is determined by the manufacturer. The iij power is input, and the output power is set so that the blade can reach the target speed, and the different speeds and corresponding output powers of the same number of segments are not set. This practice will change the control program to different settings depending on the load of the ceiling fan, and there will be a large customization problem. Furthermore, because the ceiling fan will rely on the cross-matching of the size, shape, material, etc. of the blade to create a lot of changes, but the output is set.

Referring to the first figure, the method and circuit for controlling the speed and load of the fanless motor of the ceiling fan of the present invention, wherein the circuit is installed in a general fan with a brushless motor 1 of the ceiling fan 5, comprising: a power rectification filter Unit 1〇 is used to connect the AC power and rectify and filter the AC power to DC power, as shown in the second figure. An AC power feedback unit 2 is connected to the power rectifying and filtering unit 1 ’ for monitoring the floating state of the AC power source and outputting the monitored voltage signal 1 , as shown in the second figure. A central processing unit 30 is internally provided with a control program, and is connected to the Ac power supply feedback unit 20 and receives the voltage signal output by the AC power feedback unit. A motor driving unit 40' is connected to and controlled by the power rectifying and filtering unit 1A and the 15 central processing unit 30, and the central processing unit 30 generates a three-phase brushless motor that sequentially outputs two-phase voltages to the ceiling fan, and controls the same. Running. A motor power consumption sampling unit 5 is connected to the motor driving unit and the central processing unit 30 for converting the total current consumption in the motor driving unit 4 into a digital signal and outputting it to the central processing unit 3A. For example, the second and third figures show an implementation circuit of a power consumption sampling unit, which uses current sensing IS to convert the total current into a voltage signal, and then amplifies the voltage signal by a 〇p amplifier and integrates it into a DC voltage. The central processing Cuiyuan% is converted into a digital signal to obtain the parameter of the total power consumption. ^ A motor speed sampling unit 60' is connected to the central processing unit 3, 6 201010264 ❿ 10 15 ❹ 20 Outputs the obtained rotational speed signal to the central processing unit %, the central processing unit 2 to understand the current speed of the ceiling fan motor 'The motor speed is taken from the unit 2 is the leg sense (four) to obtain the speed signal and then feedback one side wave signal to the central processing unit 3〇, where the relationship of the speed AN=( 120xF)/P is the frequency of the square wave signal, and P is the number of magnetic poles of the motor magnet that can be read from the rated power to 30.
