Definitions

  • the mover is fixedly connected to the car door preferably at the top of the car door and optionally also at the underside of the car door. If the car door has two moving car door leaves, which move together in a telescope manner or in opposite directions, whereby each car door leaf has its own mover, so that both movers are running along the same stator rail(s). This has the advantage that only one stator rail is necessary on which the movers for both car door leaves are running.
  • stator beam has a square profile with preferably four stator rails being located on each face of the square profile. Via the square profile it is easy to place stator rails of equal size on each face of the stator beam and such an arrangement facilitates the provision of a levitation control if the mover should not only move the car door but also support the car door instead of rollers.
  • the two movers of two door leaves may run over the door opening length of one door leaf. This arrangement may for example be chosen if there is no place above one of the door leaves to arrange a mover there.
  • both movers each have an active side and a passive side facing the two stator rails, whereby the active and passive sides of both movers are opposite to each other.
  • each of the two stator rails forms together with the corresponding active part of a mover a separate FSPM motor unit.
  • the car door or car door leaves of a car door is/are supported by rollers in a guiding track.
  • the FSPM motor unit only needs to move the car door or car door leaves and doesn't need to support it as the support is provided via the rollers in the guiding track. Therefore, in this case it is sufficient that only one mover for each car door or each car door leaf is provided which is then preferably located at the upper end of the car door.
  • the rollers are guided in the guiding track without essential play as to define the air gaps between the mover and the two stator rails.
  • the mover may have two opposite active sides which co-act with the corresponding stator rails.
  • the FSPM unit comprises two or more active sides (FSPM motors) without yoke. In this case the active sides share the same active parts, i.e.
  • the car door drive comprises a backup energy supply so that in case of power off it is still possible to open the car door.
  • the backup energy supply is integrated in the linear FSPM motor unit which has the advantage that all components of the door drive are accessible from one working point.
  • a floor door in the elevator shaft is during door opening and closing procedure mechanically coupled via at least one door coupler to the car door.
  • the linear FSPM motor unit moves or moves and supports the car door as well as moves the landing door.
  • the FSPM motor unit comprises several stator rails which are mounted immovable with respect to each other.
  • the closing movement of the floor door is supported by a closing weight which improves the safety of the elevator arrangement.
  • Fig . 2 shows a similar arrangement to Fig . 1 whereby in this case, the FSPM motor unit comprises a levitation control, so that the car door is supported by the FSPM motor unit and does not need rollers for its support,
  • Fig . 4 shows a view according to Fig. 3 with two FSPM motor units, one at the top as well as one at the bottom of the car door,
  • Fig . 6 shows a view according to Fig. 5 of an FSPM motor unit having a mover with two active sides designed for levitating the car door, whereby between the active parts of both sides a yoke is arranged for separately controlling both active sides
  • Figs. 7 to 9 show perspective drawings of an elevator car with a car door having two door leaves which are moved by a levitating FSPM motor unit at the top as well as at the bottom,
  • Fig . 9 shows a detail of Fig. 7 at the bottom
  • Fig . 13 shows a detailed perspective view of the stator beam with four stator rails as used in any of Figs. 7 to 12,
  • Fig . 14 shows a perspective view from below to an FSPM motor unit with levitation function used in the arrangements of Figs. 7 to 13, and
  • Fig . 15 shows a schematic view more from the front of the stator rail and mover of Fig. 10 in a 90° tilted version.
  • the mover 26 further comprises irons 40.
  • the permanent magnets 38, the coils 34 as well as the irons 40 form the active part of the mover 26 co-acting with the stator teeth of the stator rails 20, 22.
  • the mover 26 has two opposite active sides which co-act with the facing sides of the two stator rails 20, 22.
  • Rollers 42, 44 are mounted to the upper area of the mover casing 32, which rollers 42, 44 are running in/on the guide tracks 24 located above the stator rails 20, 22.
  • the FSPM motor unit 50 with the mover 52 and the stator rails 20, 22 comprises a levitation control which not only moves the mover 52 in horizontal direction as to open and close the car door 30 but it also generates an upwards pulling support force for the car door according to the bold arrow in the figure so that this arrangement does not need rollers and a roller track for supporting the mover and the car door.
  • Essential in this embodiment is that the windings 34a, b and the irons 40a, b are separated by a yoke 46 as to be controlled separately which enables levitation control as well as control of the width of both air gaps ag l, ag2.
  • Fig. 3 shows a front view of a car door 30 which is supported by an FSPM motor unit 28, 50 according to Fig. 1 or 2 at its upper end.
  • an FSPM motor unit 28, 50 is located at the upper as well as the lower end of the car door 30 so that the car door 30 is guided by the corresponding FSPM motor units 28, 50 with rollers or without rollers at the upper and lower end of the car door 30 which gives a good stability and guidance for the door support and the opening and closure movement of the car door 30.
  • Fig. 5 shows a horizontal cross-section through an FSPM unit 28, 50 as shown in Fig. 1 or 2, whereby this arrangement is particularly configured for an arrangement according to Fig. 1 where rollers are used .
  • the mover 28, 50 has two active sides 60, 62 co-acting with the stator teeth 64 of the two stator rails 20, 22 so that the two active parts together with the associated stator rail 20, 22 forms its own FSPM motor whereby these two FSPM motors don't have a yoke, so that they can’t be controlled separately.
  • This this arrangement doesn't allow the adjustment of the air gaps agl, ag2 via the active sides of the mover. This has to be done via a proper roller support of the mover together with the car door leaves as it is shown e.g. in Fig. 1. Flowever, this arrangement saves place, is easy to control and leads to a cheaper construction which is easier to install.
  • Fig. 6 shows a similar arrangement of an FSPM motor unit 28, 50 whereby the difference to Fig . 5 is the fact that between the two active sides 60 and 62 of the mover 28, 50, a yoke 68 is provided. Accordingly each active side 60, 62 of the mover 28, 50 forms an own motor with the
  • corresponding stator rail 20, 22, and both active sides 60, 62 can be controlled independently of each other.
  • the air gaps agl and ag2 can be controlled with this arrangement and the thus built FSPM motor unit 28, 50 is particularly suited for additional levitating function (support of mover and car door on the stator rails or stator beam) as well as the moving function for the car door so that no rollers are necessary for mover support and car door support.
  • this motor design is particularly adapted for the Fig . 2 arrangement.
  • the windings 34a, 34b are separate, the irons 40a, 40b are separated by the yoke 68 but the permanent magnets 38 may be common to both sides, which simplifies the structure.
  • Fig. 7 shows an elevator car 80 having a roof 86 and a bottom 88 as well as side walls 87 and a car door 30 with two car door leaves 82, 84 moving in opposite directions to open and close a door opening 81.
  • the upper and lower ends of the car door leaves 82, 84 are via screws 89 or similar connections fixed to movers 90 which are running on a stator beam 92 with a square profile 103 having four stator rails 104a,b,c,d at its circumference (see Fig. 10).
  • the thus formed FSPM motor units 100 consisting of the movers 90 and corresponding stator beams 92 are more detailed described in the following Figs. 8 to 15. The following statements refer to all these figures, which show the same embodiment in different perspectives and views.
  • the upper stator beam 92a is located and fixed to the elevator car 80 in the area of the car roof 86 whereas the lower stator beam 92b is fixed to the elevator car in the area of the car bottom 88.
  • the upper mover 90 comprises a downwards directed C-profile 102 which encompasses the four stator rails 104a-104d located at the outer faces of the square profile 103 of the stator beam 92a .
  • the stator beam 92a has on its lower end a mounting part 106 connected to the square profile 103 at its corner via which mounting part 106 the stator beam 92 is mounted to the elevator car 80, e.g. on the roof 86 or the bottom 88 or at the side wall 87 above and below the door opening 81.
  • the C-profile 102 of the mover 90 comprises at its inner sides separate active sides 112a-112d (see Fig .
  • the FSPM motor unit 100 essentially comprises four single FSPM motors having their motor force and torque added up so that the torque of this motor is fourfold the force as if only one stator rail 104 would act together with one active part of the mover 90.
  • a further advantage of this solution is that the provision of four stator rails and the corresponding active parts easily allows the levitation of the mover 90 and car door leaf 82 and also the control of the air gaps between the stator rails 104a-104d and the corresponding active parts 112a-112d in the C-profile 102 of the mover 90.
  • Fig. 13 clearly shows the stator beam 92 consisting of the square hollow profile 103 and the mounting part 106 which is connected to an edge 105 to the square profile 103 between two stator rails 104c and 104d.
  • the figure also shows the stator teeth 96 of the stator rails 104a- 104d .
  • the mover 90 also comprises the car door drive 110 with the control and power electronics for driving the active parts on the four faces 112a-112d of the C-profile 102.
  • the car door drive 110 comprises power electronics which are emitting a lot of heat which is effectively conveyed via the massive body 91 of the mover 90 which acts as a cooling element having outer cooling ribs 93.
  • a backup energy supply 114 is integrated into the mover 90 of the FSPM motor unit 100 so that in case of power off, the car door drive further gets enough energy to finish an opening or closing movement.
  • the backup energy supply 114 is releasably connected to the mover body 91, e.g. via a snap-lock connection.
  • stator beam 92 with a - particularly hollow - square profile 103 has the advantage that the stator beam 92 is very rigid so that the air gaps between the active sides 104a- 104d and the corresponding active parts 112a-112d of the mover can be easily kept and maintained by the control via the car door drive 110.
  • the invention is not restricted to the shown embodiments but may be varied within the scope of the enclosed patent claims.
  • stator teeth located on the stator rail co-acting with the active parts of the mover yoke
  • stator rails on the square profile of the stator beam
