  • the permanent magnet synchronous machine is fixed to a first bedframe and said first bedframe, through dampers, is in turn fixed to the guides of the elevator by means of parts joining the counterweight and car guides in twos.
  • the dampers are installed for the purpose of reducing the transmission of vibrations between the metal parts and the building.
  • the first bedframe where the machine is fixed is installed in the top part of the shaft, supported on the car and counterweight guides; the car and counterweight guides are located close to a first wall of the shaft, the traction pulley of the machine being in a position substantially perpendicular to the first wall and furthermore in the geometric center of the machine, and therefore in the center of the distance between the guides.
  • This pulley location greatly improves the riding comfort, decreases power consumption and as a result, increases the final performance of the elevator.
  • the hauling cables pass through the traction pulleys, the counterweight is fixed at a first end of the hauling cables, the one closest to the first wall, and the chassis of the car is fixed at a second end of the hauling cables.
  • the arrangement of the machine and the first bedframe is provided so that when the car reaches the last floor, the car exceeds the first bedframe and machine in order to have access to the machine and to be able to perform maintenance or for applications in elevators with a limited last stop.
  • the fact that the car can go past the height of the machine and first bedframe is achieved because the machine and first bedframe are located between the guides of the counterweight and of the car.
  • the car roof is used as a working surface.
  • the car is fixed in a chassis which slides along the guides, and depending on how this chassis is carried out, the following embodiments exist:
  • Figure 1A shows a representation of the shaft, guides, machine, counterweight, chassis of the car and car.
  • Figure 1B shows a detail of the machine of the invention.
  • the car and counterweight guides 11 on which the two parts 12 are screwed can be seen in the elevator shaft.
  • Two dampers 13 are placed on them, and fixed on the dampers 13 is the first bedframe 14 which the machine 15 is fixed to.
  • This configuration prevents having to fix the machine to a wall or to the ceiling of the shaft, therefore not depending on the constructive quality of the walls or their strength, since the forces of the machine in this invention are transmitted through the guides to the elevator pit.
  • the machine is always located in the top portion of the shaft.
  • the car and counterweight guides 11 are on the same side of the shaft, the traction pulley 321 of the machine is a position substantially perpendicular to the wall of the shaft close to the guides 11 and furthermore, by means of the external rotor motor and pulley, in the geometric center of the machine.
  • the hauling cables 16 pass on one side of the pulley of the machine to the counterweight 17, and to the chassis of the car 18 on the other side; the car 19 moves within the chassis 18 which it is fixed to by the ground and ceiling.
  • FIGS 3A-3C show different views representing the machine 300.
  • the stator 30 of the machine is actually the shaft which is rigidly joined to the frame 31 of the machine;
  • the rotor 32 provided by the invention is the outer rotating portion, made up of a cylinder in the center of which the traction pulley 321 is machined, then attached, and at each end there is a braking area 322 on which the brakes 33 act on each one of them; there is a total of 2 or 4 brakes, according to the application.
  • Figure 4 shows a detail of the position of the elevator during maintenance.
  • the chassis 18 of the car 19 is suspended with parts 41 to the first bedframe 14 of the machine; these parts 41 allow joining the chassis 18 of the car 19 to the first bedframe 14 in order to keep the car 19 suspended such that maintenance tasks from the roof of the car 19 are carried out with no risk for the workers.
  • the roof of the car 19 is used as a working surface. It is important to again highlight that the elevator of the invention allows all these tasks with complete independence from the building and without having to suspend the car 19 from the walls thereof.
  • the brakes are completely accessible for the technician. Furthermore, the machine can always be installed at a sufficient distance with respect to the ceiling of the shaft in order to have enough space, since, if necessary, the chassis 18 can reach a greater height than the first bedframe 14 of the machine, as can be seen in the plan view of Figure 2C.
  • Figures 1A and 2A-2C show the first embodiment (i), 1:1 suspension without return pulleys with a braced C-shaped chassis, which allows very limited dimensions under the car, which is particularly indicated for the application of elevators with a limited pit, that is elevators having a pit in the shaft under the bottom floor with a height that is less than normal.
  • FIGS 5A-5D show the second embodiment (ii), 1:1 suspension without return pulleys with a back-pack chassis, in which the car 51 moves within the back-pack chassis 52.
  • This manner of carrying out the chassis allows exceeding the machine, that is the chassis 52 reaches a greater height than that of the first bedframe 14.
  • This embodiment allows being able to carry out elevators with a limited last stop, that is elevators in which the height in the shaft between the level of the last floor and the ceiling of the shaft is smaller than normal.
