Definitions

  • the present invention relates to a motor and a method of assembly the motor as a direct drive element for a laundry treatment appliance.
  • Laundry treatment appliances are u.a. Washing machines, spin dryers or Dryer. These machines include a rotatably mounted in a tub Drum that is powered by a motor. The drum is for recording formed by laundry or laundry and in a known manner from the front or Chargeable from above.
  • direct drives ie directly, i.e. without transmission of power by means of belt or gear, the drum shaft driving motors.
  • Direct drives can be used as external rotor or be designed as an internal rotor. The direct drive eliminates wearing parts like belts or gears.
  • the stator is circular arranged Truminated cores) with insulation and pole winding.
  • the stator with its windings forms the rear wall of the tub and the bearing cross with bearing bore for the drum axis one unit. They are designed as plastic injection molded parts with inserts. adversely this is a bad heat dissipation and a large amount of material Non-tracking plastic.
  • the drum axis is opposite the stator for a centric seat stored extra with a ball bearing.
  • the additional warehouse means a larger additional effort.
  • a bearing bore in a bearing cross or a tub rear wall is for the Seat of ball bearings accurately edited.
  • the invention uses these anyway necessary, defined and smooth bore for centering the stator.
  • the stator may be made of e.g. two electrically insulating plastic shells that the Carrying laminated core, be composed.
  • the two plastic cups, an inner shell and an outer shell are precise molded parts.
  • the inner shell has in the middle the protuberance, which is exactly in the Bearing bore fits.
  • the two plastic shells in addition to their holding function the insulation for the pole windings of the stator poles. So the necessary large creepage current path between stator laminated core and stator winding complied with can be, overlap the two plastic shells.
  • the laminated core is placed in the shells.
  • the two Shells hold together by detents (e.g., on the inner shell).
  • detents e.g., on the inner shell.
  • To the winding of the poles can be the complete stator with the inner protuberance be placed centrally on the supporting star and conventional, e.g. with screws, be fixed. These screws are through the two spacers of the outer Plastic shell screwed into the bearing cross or the tub rear wall. In order to they are insulated against the laminated core of the stator.
  • the outer plastic shell according to the invention has above the Polisol ist towards the rotor bell, e.g. spouted noses.
  • the outer diameter over the noses corresponds to the inner diameter of a rotor bell with their permanent magnetic poles.
  • these noses serve too a trouble-free assembly of the rotor bell.
  • the rotor bell is over the noses pushed in the direction of the drum. This pushes the inner hole of the bell on the drum axis and the rotor bell is kept so centric. she can itself driven by the magnetic forces of the permanent magnetic poles do not hit the soft magnetic poles of the stator. Thus, a damage the permanent magnets of the rotor bell excluded.
  • the noses are laterally offset outwards the permanent magnet poles of the rotor bell in the interior.
  • the rotor bell can turn freely. She is on the drum axis in every conventional Way, e.g. with a nut, fixable.
  • For an internal rotor is valid in analog The same principle as for the external rotor described above.
  • the noses on the outer plastic shell need not be injected.
  • the same assembly is with a nosepiece, e.g. made of plastic, which is on the outside Shell is snapped, possible.
  • the pole windings for the stator poles are wound independently of this and before attaching of the nose part are pushed over the poles.
  • stator in the bearing bore of the bearing cross or To center the tub rear wall, you can also with an auxiliary part for mounting of the stator.
  • the auxiliary part then has the middle preferably cylindrical or conical protuberance that fits exactly in the bearing bore.
  • the Auxiliary part could e.g. be designed as a bell into which the stator with his largest outer diameter just fits. The complete stator would work together pushed with the auxiliary part on the bearing cross or the tub rear wall and then, e.g. screwed with screws through holes in the auxiliary part. After that would the auxiliary part withdrawn and the runner as described above assembled.
  • FIG. 1 shows the sectional view of a direct drive fully assembled a laundry treatment device.
  • the tub of the laundry treating appliance is only partially shown with its rear wall 1.
  • the bearing cross 2 fixed in place.
  • the bearing cross 2 has a hole in the middle 3, which is precisely edited for the seats of a storage 16.
  • a cylindrical protuberance 5 on a stator 18 is formed on an inner plastic shell 4. She protrudes precisely into the hole 3 of the bearing cross 2 and thus guarantees the centric seat of the stator 10.
  • the stator 18 is in a known manner by Screws 11 held firmly on the bearing cross 2.
  • the screws 11 are through high spacers 8 isolated against laminations of the stator 18.
  • the stator 18 is through the inner plastic shell 4 and an outer plastic shell 7 formed with inserted laminated cores.
  • the plastic shells 4 and 7 are held together by snap hooks 6.
  • the snap hooks 6 are attached to the inner plastic shell 4. In the assembled state, the Plastic cups 4 and 7 held by the screws 11 firmly in position.
  • Polwicklungen 10 of the stator poles are opposed by the plastic shells 4 and 7 the laminated cores isolated.
  • a rotor bell 12 carries in a known manner inside permanent magnetic poles 13. It is in the assembly in the direction of movement 17, ie from the outside to a Drum shaft 14 pushed. In this case, the rotor bell 12 comes into contact first with lugs 9 of the outer plastic shell 7. The poles 13 of the rotor bell 12th slide during assembly over the lugs 9 of the outer plastic shell 7. At the same time the inner hole of the rotor bell slides over the drum axis 14 finished assembled state are the lugs 9 at a distance next to the poles 13 of the Rotor bell 12. The rotor bell 12 can rotate freely. She is by a mother 15 fixedly connected to the drum axis 14.
  • the described direct drive can also be formed by a motor, the includes a stator 18 which has been mounted as shown in FIG.
  • An auxiliary part 19 for mounting the stator 18 has centrally a cylindrical protuberance 5.
  • the Stator 18 is held in a bell 20 of the auxiliary part 19.
  • the auxiliary part 19 is with the stator 18 on the bearing cross 2 and the tub rear wall 1 set. It centered over the cylindrical protuberance 5.
  • the stator 18 is e.g. With Fixes screws 11, and then the auxiliary part 19 is withdrawn.
