Definitions

  • the invention relates to a door drive for an automatic door, in particular for an automatic sliding and / or elevator door, comprising at least one door leaf, comprising a motor for generating a driving force and a (n) guided in the opening and closing direction of the door belt or chain Transmission of the driving force on the door leaf, wherein the motor is mounted such that its shaft is perpendicular to the opening and closing direction of the door and / or aligned horizontally.
  • the invention has for its object to provide a door drive, which avoids the disadvantages of a transmission and yet is compact buildable.
  • a drive pinion or pulley for driving the belt or the chain is mounted on the shaft of the motor.
  • the drive pinion or pulley is in particular attached to a freestanding end of the shaft. This results in the advantage of universal integrability in the door system.
  • the engine - preferably completely - within a door fighter or a lintel at the upper end of the door, in particular above a car of the elevator, is arranged.
  • no space is required above the elevator car of the elevator installation for installation or assembly of the door drive. This results in special advantages compared to a solution with a countershaft, in which the engine must be mounted usually above the door fighter.
  • any fixed built into the door frame crossbar in particular a horizontal profile between the lower door system and an upper part, in the case of an elevator of the upper part of the car.
  • the door striker is usually arranged above the door leaves of the door.
  • attachment of the motor according to the invention further provides the advantage that one and the same, for example, as a spare part reproached engine, both on the left and at the right end or at any position between the door striker can be mounted and thus the distinction between the left and right Wave output, as necessary with gear motors, can be omitted.
  • the motor together with the drive pinion or pulley in the shaft direction has an extension of less than 100 mm, preferably less than 80 mm.
  • the diameter and / or the edge length of the motor preferably lies in the range between 50 mm and 200 mm, preferably in the range between 80 mm and 160 mm. With such dimensions, the engine including drive sprocket or pulley in a lintel or door striker with particularly small dimensions of height and / or width less than 110 mm can be accommodated.
  • the length of the motor measured without bearing, drive pinion and any electronic components is less than 60 mm, in particular less than 36 mm.
  • the length of the motor - measured at a distance of at least 35 mm from the shaft - without bearing, drive pinion and any electronic components is less than 60 mm, in particular less than 36 mm.
  • the engine has a drive torque of at least 0.008 Nm / kg or at least 0.01 Nm / kg door mass, in particular a drive torque from the range of 3.0 Nm to 4.5 Nm, preferably from the range of 3.5 to 4.0 Nm.
  • the motor is electronically commutated and / or brushless.
  • the aforementioned embodiments can be realized in a particularly advantageous and compact manner.
  • the mechanical commutation system i. the commutator brushes
  • a motor-mounted control unit which is also called BL controller (brushless controller).
  • BL controller brushless controller
  • the motor is also preferably designed as a, in particular permanently excited, synchronous motor.
  • the door drive further preferably has a control unit with an installed control program for moving the door into its open and / or closed position.
  • the control unit is in particular so prepared that the engine - at least in normal operation - with a speed of less than 600 U / min, preferably with a speed of less than 500 U / min, operated.
  • the angle sensor is mounted on the side facing away from the drive pinion or pulley side of the motor.
  • the angle signal of the angle sensor is used according to a preferred embodiment for driving a commutation circuit for electronic commutation of the motor.
  • the angle signal of the angle sensor is - additionally or alternatively - supplied as input to a door position control device.
  • the angle signal of the angle sensor is used for both purposes, resulting in a special savings in space, effort and expense.
  • the angle encoder in the axial direction an extension of max. 40 mm, preferably of max. 20 mm.
  • a total length of motor, drive pinion or pulley and angle encoder in the shaft direction of less than 110 mm, preferably less than 98 mm, appropriate.
  • the angle transmitter preferably has a resolution of at least 10 bit / 360 °, in particular of at least 11 bit / 360 ° or of at least 12 bit / 360 °.
  • This is of particular advantage in connection with a high-torque, high-torque motor.
  • a high temporal resolution is possible even at low speeds. This means that even very slow door speeds can be adjusted down to standstill.
  • the high resolution leads in a gearless drive and in particular in a sinusoidal control of the motor to a nearly harmonics-free torque deployment, which characterized by very good concentricity with low noise levels.
  • the angle encoder is designed as an absolute encoder.
  • an absolute value encoder is understood to mean an angle measuring device which outputs position information in the form of a numerical value, possibly encoded, which is unique over the entire resolution range of the absolute value encoder, so that no initial reference or calibration travel, as for example with an incremental encoder , is needed.
  • the absolute value encoder can preferably completely dissolve at least one revolution (360 °) and is designed in particular as a single-turn encoder.
  • An absolute value encoder has the advantage over a Hall sender or a quadrature encoder that the rotor position is immediately available at any time, ie also immediately after the power supply system has been switched on. It eliminates the previously necessary synchronizing the rotor angle based on a reference point or complex calculations. In addition, there is a considerable cost advantage over a resolver solution at the encoder itself, but also on the part of the design of the control unit (control electronics). Compared to a resolver solution also results in a lower height.
  • an angle encoder which operates on a magnetic principle and is designed in particular as a magnetic absolute encoder.
  • the magnetic absolute encoder or rotary encoder operates in particular according to the GMR effect.
  • the Giant Magneto Resistance (GMR) effect is a quantum mechanical effect observed in thin film structures of alternating ferromagnetic and non-magnetic layers.
  • the evaluation is preferably carried out in a Wheatstone bridge. This can provide a sine / cosine signal in the two sub-bridges, allowing each position to be identified at full angle (360 °).
  • the magnetic absolute value encoder or rotary encoder is alternatively formed by interconnecting a plurality of Hall sensors, preferably 3 or 6 Hall sensors.
  • An intelligent evaluation electronics eg based on DSP, allows a clear detection of the entire full circle.
  • FIG. 1 shows a door 1 of an elevator with two equal-sized, counter-rotating door leaves 2, 3.
  • the door 1 is enclosed by a door frame 4, which is closed and supported in the upper part of a door striker or lintel 5.
  • the opening and closing direction of the door leaves 2, 3 is denoted by 7.
  • the door mass is up to 400 kg.
  • FIG. 2 shows the area of the door fighter 5 in a front view, as opposed to FIG. 1 removed fender aperture would represent.
  • an electronically commutated and brushless, permanently excited synchronous motor 10 is arranged such that its motor shaft 11 perpendicular to the opening and closing direction 7 and horizontally, in the FIG. 2 perpendicular to the drawing plane, runs.
  • a drive pinion, drive wheel or pulley 12 or the like is attached.
  • Pulley 12 has a tough elastic toothed belt 16, which transmits the driving force of the motor 10 to the door leaves 2, 3.
  • FIG. 3 shows the arrangement of FIG. 2 in a view from above. It can be seen that the motor 10 is gearless on the partially rubber-made timing belt 16 acts. The pulley 12 is seated directly on the shaft 11 of the motor 10. The diameter D of the motor 10 is 160 mm.
  • a magnetic absolute encoder 20 Coaxial with the motor shaft 11, ie on the illustrated axis of rotation A of the motor 10, a magnetic absolute encoder 20 is mounted. This one will be in FIG. 4 explained in more detail.
  • the depth extent L of the entire assembly consisting of motor 10, drive wheel 12 and angle encoder 20 is less than or equal to 110 mm. Due to this flat design, the entire arrangement in the door 5 or lintel (lintel) with very compact dimensions can be accommodated.
  • FIG. 4 the entire arrangement consisting of motor 10, drive wheel 12 and angle encoder 20 in detail and interaction with a door drive associated with the control unit 24 is shown. Not only the motor 10, but also the angle encoder 20 is designed particularly flat:
  • Depth extension L 2 of the angle sensor 20 approx. 30 mm.
  • Depth extension L 1 of motor 10 together with drive wheel 12 about 80 mm.
  • Total depth or total length L less than 110 mm.
