  • Publication number: 20210233039
    Abstract: Disclosed is a soft measurement method of DXN emission concentration based on multi-source latent feature selective ensemble (SEN) modeling. First, MSWI process data is divided into subsystems of different sources according to industrial processes, and principal component analysis (PCA) is used to separately extract the subsystems' latent features and conduct multi-source latent feature primary selection according to the threshold value of the principal component contribution rate preset by experience.

  • Publication number: 20140147260
    Abstract: A heat dissipating fan includes a stator and a rotor. The stator includes a bearing and a winding structure, wherein the bearing is disposed in the winding structure. The rotor includes a fan wheel, a ring-shaped casing and a magnetic member, wherein the ring-shaped casing is disposed in the fan wheel and the magnetic member is disposed in the ring-shaped casing. The fan wheel has an axle inserted into the bearing such that the winding structure is located within the magnetic member. At least one protruding portion protrudes from one side of the ring-shaped casing inwardly and is extended below the winding structure so as to hold the magnetic member and interfere with the winding structure.

  • Patent number: 8421390
    Abstract: A fan motor control device for controlling the soft start of a fan motor is disclosed. The fan motor control device comprises a converter, a starting capacitor, and a controller. The converter sends out a control signal to the controller based on an input pulse-width modulation signal. The starting capacitor is coupled between a voltage source terminal and a controlled terminal of the controller. Thereby, based on an input voltage to the controlled terminal, the controller controls the soft start of the fan motor. For the soft start period, the magnitude of the input voltage is determined by the base working voltage outputted via the voltage source terminal. While for normal operation, based on the input voltage to the controlled terminal, the controller controls the speed of the fan motor, with the magnitude of the input voltage determined by the control voltage outputted by the converter.
