  • Publication number: 20220018570
    Abstract: A method and an air treatment system with a fan arrangement having kmax fans. The respective speed ni of the fans is regulatable. A control and regulation system regulates the speeds ni, where i?[1, 2, 3, 4, 5, . . . , k] of the k of kmax fans. A certain operating point of the air treatment system is set with a specific overall power Ptotal of the air treatment system as a function of the respective set speeds ni. The control and regulation system has a mechanism to determine the speed combination(s) of the speeds ni of the k fans where the total power Ptotal of the air treatment system is reduced or is minimal compared to other speed combinations of the speeds ni.

  • Patent number: 10072671
    Abstract: A diffuser (3) for a fan (2) of axial, radial or diagonal type of construction, has an inlet opening (10) and having an outlet opening (20) for a gaseous medium which flows through a diffuser interior (I), which is enclosed by an outer housing (30), in an axially oriented main flow direction (S) from the inlet opening (10) to the outlet opening (20). The cross section of the diffuser interior (I) increases from the cross section (11) of the inlet opening to the cross section (21) of the outlet opening (20), wherein the outer housing (30) forms an outer diffuser part (AD) which delimits the diffuser interior (I) to the outside. Along the main flow direction (S), the cross section of the outer diffuser part (AD) changes from a circular cross section (31) at the inlet opening (10) to a non-circular cross section (32) at the outlet opening (20).

  • Patent number: 9531239
    Abstract: A motor, comprising an electronics housing having integrated motor electronics, a stator, and a rotor. The stator comprises a stator bushing and a laminated stator core having motor windings. The stator bushing is arranged axially between the electronics housing and the rotor. The motor according to the invention has an air-conveying element connected to the rotor in a rotationally fixed manner and at least one axially extending passage opening arranged in the stator bushing. The air-conveying element is arranged axially between the stator bushing and the rotor and has a circumferential axial intake opening on the side of the stator bushing. During motor operation, the air-conveying element sucks in an axial volumetric air flow at an external wall of the electronics housing through the intake opening and the passage opening.

  • Publication number: 20150176594
    Abstract: An impeller has an inlet and outlet. A bottom disc has an external diameter. A top disc concentric to the bottom disc at an axial distance therefrom has a suction opening for the inlet. A plurality of forward-curved blades are arranged between the bottom disc and the top disc. A flow channel has an inner inlet side and an outer outlet side formed between adjacent blades. The channel is curved convexly viewed in the running direction of the impeller. The external diameter of the bottom disc is at least 20% greater than the internal diameter of the suction opening. The top disc forms a guiding surface and an angle is formed between a tangent on the guiding surface at the inlet to the suction opening and a tangent on the guiding surface at the outlet from the flow channel on the air outlet side is at least 30°.

  • Patent number: 8217540
    Abstract: The invention relates to an electric motor with a stator and an external rotor, comprised of a rotor bell and a rotor cover that acts as a fan wheel. The rotor bell has several apertures in its bell floor. The rotor cover has several exhaust ports. The rotor cover is shaped like a plate and consists of a plate base and an annular wall. The exhaust ports are preferably evenly distributed in the annular wall. The inside of the plate base of the rotor cover that faces the rotor bell has several radially extending interior blades that are fixedly connected to it.
