Embodiment Construction
[0023] The present invention is described in further detail below in conjunction with accompanying drawing:
[0024] refer to image 3 According to the present invention, the linear output fan control method based on the rotor speed coupling adjustment includes the following steps:
[0025] 1) Select several typical working condition points, and obtain the parameters of each typical working condition point through experiments, wherein, the parameters of the typical working condition points include the current value of the motor 1, the fan speed and the angle of the moving blade 4, and establish the current value of the motor 1 The corresponding relationship between the value and the fan speed and the angle of the moving blade 4;
[0026] At a certain working condition point, the determined current value I of the motor 1 has a corresponding relationship with the fan speed P and the angle D of the moving blade 4. Therefore, the typical working condition point X can be used as I...
