  • the Drive unit arranged in a machine room, in the elevator shaft or in the elevator shaft and his shaft wall is arranged.
  • Elevator drive positioned next to the carriageway is felt to be detrimental that there provided drive units require a lot of space, so that, for example, with the same car size opposite conventional lifts larger shaft widths and / or Depths are required or additional Shaft wall recesses are necessary. In particular, can this lead to the usual shaft cross-sectional dimensions after ISO 4190-1 can not be met.
  • WO 01/27016 A1 is a drive for an elevator with a ropeway car in one vertically extending shaft is movable up and down, and with a traction sheave for the ropes of the car and one parallel to the traction sheave arranged Drive motor known, the drive motor by Transmission belt is connected to a pulley, the is arranged coaxially with the traction sheave.
  • the Drive designed so that the drive motor with a provided on the motor shaft acting braking device is.
  • a disadvantage of this structure is considered that he builds big.
  • the arrangement of Braking device on the motor shaft leads to a very long construction, so that the drive inevitably in the upper or lower area of the shaft in the Projection area of the car must protrude.
  • the present invention seeks to be a small built drive for engine roomless elevator systems ready to put in the shaft at any height next to the roadway of the car can be arranged without the Shaft to enlarge and no additional Shaft wall recesses.
  • the drive according to the invention is characterized by a Combination of features, all to one Reduce the required horizontal space, allowing a positioning of the drive next to the roadway a car essentially in any vertical Height is possible without the necessary shaft widths to increase compared to conventional solutions.
  • the electric motor of Combining drive with a counter can do that Required drive torque of the motor in a suitable manner be reduced, resulting in a significant reduction of Size of the motor, in particular the axial size and its provisioning costs is feasible.
  • the braking device arrange so that they are directly on the traction sheave can lead to the fact that there is no safety-relevant requirements.
  • the further provided parallel arrangement of the axes of the Traction sheave and the electric motor causes that Traction sheave and braking device above or beside the Electric motor can be arranged, causing the resulting horizontal extent (in the axial direction the motor shaft or traction sheave axis) of these components is further minimized.
  • the invention provides, the Traction sheave together with the Vorlegerad and the Store the brake disc flying on the traction sheave axle.
  • the countershaft is as a belt countershaft with a reduction ratio of 2: 1 to 5: 1 executed.
  • the required drive torque the electric motor is reduced according to this factor, thereby minimizing the size of the engine and a Reduction of deployment costs is possible.
  • the required engine speed is typically still around a factor of 2 to 3 below the speed of a conventional one frequency-controlled transmission drive and is the latter, in particular with regard to the arrangement in the shaft, clearly due to lower noise emissions think.
  • the copy can also be with a gear ratio of 1: 1.
  • the drive according to the invention provided braking device as a jaw or disc brake formed, wherein the brake disc diameter advantageously larger than the pulley diameter is.
  • the brake disc diameter advantageously larger than the pulley diameter is.
  • the braking device as wholly or partly inside the traction sheave to perform arranged multi-disc brake.
  • Multi-disc brake proves to be special in practice effective braking device.
  • the Drive is the electric motor Synchronous external rotor motor arranged on the rotor Permanent magnet formed, wherein the outer-running Rotor on one side on one by the engine extending shaft is fixed, and on the other side the shaft the countershaft, in particular a pulley, is arranged flying.
  • the shaft thus extends through an axial opening formed in the stator. In this Opening are expediently appropriate storage means educated.
  • An external rotor motor provides in principle cheaper drive lever ratios than a corresponding Internal rotor motor available as the effective Drive lever arm radially outside the engine air gap lies.
  • the electric motor has a removable Housing on which completely encloses the rotor, wherein the housing on the opposite side of the pulley a pickup integrated in the motor receives.
  • a housing On such housing is, for example, under Safety aspects advantageous.
