Definitions

  • the invention relates to a fan unit according to the preamble of claim 1.
  • an asynchronous motor is centered within a fan wheel and arranged on one of the fan wheel opposite support plate is attached to the fan to drive.
  • an asynchronous motor there is an internal one Stator and an outer rotor provided, the regulation of the Fan rotation speed occurs due to voltage change.
  • Another known fan unit uses an EC motor used, i.e. an electronically commutated motor, which drives the fan impeller and that described in the above Way on a support plate for driving the impeller is attached.
  • the commutation of the EC motor occurs in each case a bouncing moment on that wheel works and thus results in noise. This noise development is consequently on the surrounding Housing and transmits an unwanted noise during the operation of the fan unit concerned.
  • the invention has for its object a fan unit of the type mentioned in the introduction to the Conveying capacity and noise is improved.
  • the fan impeller rotatably supported by a shaft in the fan impeller opening.
  • the components of the drive motor are located here partly on a housing area facing the fan impeller is and partially on a fan impeller Ring.
  • the fan unit according to the invention described ensures that that the actual motor is peripheral on the outside to the fan impeller. As a result, the overall height of the entire Motor arrangement not compared to known arrangements increases while reducing noise and reduction of drive power.
  • the noise development can additionally thereby improved, i.e. be reduced that the fan impeller receiving shaft with a structure for sound insulation is provided without problems regarding the spacing or enlargement of the fan unit compared to the known fan units.
  • structure-borne noise insulation devices also decoupling by separating the one generated by the fan impeller Sound to the outside on the mounting units and causes the outer sheet metal housing.
  • the drawing shows a partially sectioned representation a fan unit, in particular for use in Clean room systems, for example for the production of semiconductors.
  • the fan unit has a housing 1, which consists for example of sheet metal and which is preferably provided on the inside with sound insulation 2 is.
  • this housing 1 there is preferably a central one Opening 3 for receiving a fan impeller 4.
  • Below The fan impeller 4 has a filter 5.
  • the housing 1 with filter 5 is in a conventional manner in a ceiling grid 6 used.
  • the storage units 8, 9 are each on trusses, carrier plates 10, 11 or the like attached, the trusses or support plates 10, 11th are connected by rods 13, 14 and the rods 13, 14 can result in a cage-like housing.
  • the rods 13, 14 extend parallel to the shaft of the fan impeller 4.
  • the crossbeam 10 or the carrier plate 10 is according to the drawing firmly connected to the housing 1 and is located approximately in the plane of the opening in the housing 1, i.e. about in the level or slightly above the level of the top facing housing area.
  • the fan impeller 4 attached to the shaft 7 and is opposite the in the drawing with 17 indicated inlet nozzle of the rotor in Flow direction offset downwards.
  • the flow direction is illustrated by arrows 15.
  • a ring is arranged on the fan impeller 4, which is denoted by 16 and compared to that denoted by 2a upper housing surface is spaced.
  • Larger diameter ring 16 are components of the Drive motor arranged, namely peripheral to the shaft 7.
  • 18 denotes a rotor carrier, 19 a non-metallic carrier.
  • a rotor armature 20 and a permanent magnet 21 is opposite the permanent magnet 21, a stator winding 22 provided, furthermore a stator core 23 made of transformer sheet, a non-metallic carrier 24 and a cover plate 25. All of the above engine components are therefore ring-shaped to the shaft 7 and are partially connected to the impeller 4 and partially fixed to the housing 1.
  • the drive motor formed peripheral components to the fan impeller 4 and preferably in the area of the inflow nozzle 13 of the rotor is provided.
  • the guide vanes belonging to the rotor are indicated in the drawing by reference numeral 27.
  • the inlet area of the impeller 4 lies within of the ring 16 and is indicated at 26.
  • the ring 16, which carries the motor components on the fan impeller side is sufficiently spaced from the housing 1, namely in the peripheral direction as well as in the axial direction.
  • the drive motor is generated by generating variable frequencies such as operated a synchronous motor and therefore has compared to no torque jumps for an EC motor, i.e. it is extraordinary low noise with low drive power guaranteed.
  • Ball bearings are provided with structure-borne noise insulation.
  • structure-borne noise insulation can, for example, rings on the outside of the ball bearings be provided, which the ball bearings at least in some areas overlap and insulation from the mounting cage and cause towards the outer sheet metal housing.
  • the shaft 7 is clamped axially either at the upper and / or at the lower end or in the upper and / or lower bearing unit 8, 9, with the bearing shaft 7 alternatively being axially and displaceably arranged on one side only can be.
  • the ring 16 is axially spaced from that plane which is defined by the housing front 2a, so that the housing-side motor components on the housing 1, running in a ring, can be arranged there.
