Definitions

  • the invention relates to a drive for cable lifts with an electric drive motor, which is coupled to a traction sheave, over which the drive cable is guided.
  • Gearless drives with preferably DC motors are normally used for elevators with high driving comfort and high speeds, but synchronous and asynchronous motors are also used.
  • gearless external rotor motors consists of the following main components: an external rotor, a traction sheave with double bearings, an internal stator with a bearing plate, a fixed axis and a second bearing plate with a brake, which acts on the driving disc from the inside .
  • This external rotor motor is available as a direct current as well as a three-phase motor and can be broken down into its individual components, external rotor and stator as well as traction sheave. As a result, this drive motor can be easily disassembled into the machine room and assembled on site.
  • the drive motor is formed by interconnecting a plurality of electric motors, and synchronous control brings about synchronization of these individual electric motors.
  • the individual electric motors are preferably constructed in the same way and modularly, so that they can be disassembled into their individual components as in the known gearless external rotor motor described.
  • the synchronization control is preferably carried out by an electronic current, voltage and frequency converter.
  • Such electronic current, voltage and frequency converters for the purpose of synchronizing several electric motors are widely known.
  • gearless electric motors are mechanically rigidly connected in series.
  • the gearless external rotor motor described above is preferably used.
  • a separate cable strand is provided for moving the elevator car and a counterweight, and an electric motor with a traction sheave is provided for synchronously driving each cable strand.
  • two electric motors, each with a traction sheave are provided in parallel, and a common traction cable is driven by both traction sheaves in the manner of a looped sheave.
  • the gearless external rotor motor described is advantageously used.
  • each of the two electric motors of the exemplary embodiment described above is formed by a plurality of gearless external rotor motors connected in series.
  • Geared motors can also be used both for the drive concept, in which a separate rope strand for moving the elevator car and a counterweight and an electric motor for synchronously driving each rope strand are provided.
  • the geared motors should then be implemented in the same way and with the same transmission ratio. However, this is not inevitable since it is preferred by electronic Synchronous control can also synchronize rotating electric motors with different speeds.
  • Geared motors can also be used when two electric motors are used, each with a traction sheave in parallel, a common traction cable being driven through both traction sheaves in the manner of a looping sheave.
  • Fig. 1 the known gearless external rotor motor 1 is shown. This consists of the following main components: an external rotor 2, a traction sheave 3 with double bearings, an internal stator 5a with end shield 5, a fixed axis 6 and a second end shield 4 with brake, which acts on the traction sheave from the inside.
  • two gearless external rotor motors 11 and 12 are mechanically rigidly connected in series.
  • An additional set of the stator and the external rotor is mounted on the extended rigid axis 6.
  • the traction sheave 15, 15 ' is also provided in double width.
  • the constructive multiplication of the basic components of the gearless external rotor motor shown in FIG. 2 at least doubles the achievable moments with the same size of the individual modules.
  • FIG. 3 A similar embodiment 10 'results from FIG. 3, in which a total of three gearless external rotor motors 11, 12, 13 are mechanically rigidly coupled one behind the other on an elongated rigid axis 6.
  • One in Figs. 2 and 3 electronic synchronism control not shown, ensures synchronous, tension-free operation of the motors 11 and 12, or 11, 12 and 13, which are rigidly coupled one behind the other.
  • the synchronism control used is preferably designed as an electronic current, voltage and frequency converter and using microcomputers built up. Such a converter regulates the current, voltage and frequency of each motor independently, so that both or all three motors rotate synchronously and the respective load transitions are absorbed in the same way by all motors. Since the structure of such an electronic synchronous control is known per se, it is not explained in more detail.
  • the embodiment shown in FIG. 4 and designated 20 also contains two gearless external rotor motors 11 and 12, which, however, are not mechanically coupled but are only synchronized by an electronic synchronous control so that their direction of rotation is opposite.
  • the torque of each motor 11, 12 is transmitted to the elevator car (not shown) and to the counterweight via its own cable strand 21, 22. Twice the torque is also available to accelerate the cabin.
  • the fixed axles 6 and 6 'as well as the end shield 4 and 4' with brake and the end shield 5 and 5 'as well as the traction sheaves 15 and 16 are each duplicated.
  • the arrangement shown in Fig. 4 can also be carried out with geared motors, which are preferably arranged so that the traction sheaves face each other.
  • two gearless external rotor motors 11 and 12 are each not mechanically rigidly coupled to a traction sheave 15 and 16, but are connected in parallel.
  • the parallel connection is done by guiding the rope 21 in the manner of a looping pulley over both traction sheaves 15 and 16, see above that with this arrangement the sum of the individual torques of the motors is also available.
  • Geared motors can also be used with this arrangement.
  • the last two based on the fig. 4 and 5 described embodiments of the cable elevator drive according to the invention have the advantage that the static load of the elevator is distributed over two axes, so that the individual axis can be dimensioned weaker.
  • synchronism fluctuations of the motors that occur can be compensated for by the elasticity of the ropes or by slippage of the traction sheaves.
  • the embodiment 30 shown in FIG. 5 can also be configured with one of the FIGS. 2 and 3 shown embodiments are combined, in each of which instead of just a gearless external rotor motor several such motors in the type shown in FIGS. 2 and 3 are mechanically rigidly connected in series and work on an axis.
