Definitions

  • the invention relates to a door drive for an automatic door, in particular for an automatic sliding and / or elevator door, which has at least one door leaf, with an electric motor for generating a driving force, a drive device for controlling and / or regulating the electric motor, a / r in Opening and closing direction of the door guided belt or chain for transmitting the driving force to the door leaf, and with a door position control device.
  • DE 103 39 621 A1 discloses a brushless electric motor, DE 10 2004 034 636 A1 a direct drive with rotary encoder.
  • JP 2006 197750 A discloses a door drive according to the preamble of claim 1.
  • the invention is based on the object, a door drive of the type mentioned in a simple manner and yet inexpensive and compact form.
  • the angle signal of the angle sensor is thus used both for the purpose of motor commutation and for door position control, resulting in a special savings in space, effort and costs.
  • the angle signal can be used in addition to the position detection of the door for detecting the speed of the door.
  • the angle sensor is working according to a magnetic principle, designed as an absolute encoder and prepared for unambiguous scanning of a complete revolution (360 °) of the electric motor.
  • Electronically commutated and / or brushless electric motors are known as such.
  • the mechanical commutation system ie the commutator brushes
  • a motorized control unit also called a BL controller (brushless controller).
  • BL controller brushless controller
  • several high-current silicon chips and a programmable microprocessor take over the task of the brush apparatus, that is, the wear-resistant and failure-prone interaction of copper fins and carbon brushes.
  • sensorless controllers eg in DE 103 46 711 A1 described, and controllers which have to determine the current rotational position of the motor an angle or rotary encoder, for example in the form of an optical encoder, a photoelectric sensor, a Hall sensor encoder, in particular a digital Hall sensor with eg 6 states resolved per revolution , a quadrature encoder or a resolver, a special resolver that operates on an electro-inductive basis and provides analog information about the angular position of the motor, coded as sine and cosine ,
  • Simple Hall sender and Quadraturencoder have the disadvantage that the rotor position is not at any time, namely not immediately after switching on the power supply network, immediately available. Therefore, a separate synchronization of the rotor angle based on a reference point or complex calculations is necessary.
  • an absolute value encoder is understood to mean an angle measuring device which outputs position information in the form of a numerical value, possibly coded, which is unique over the entire resolution range of the absolute value encoder, so that no initial reference or calibration travel, such as, for example, is required. with an incremental encoder, is required.
  • the absolute value encoder of the door drive is designed in particular as a single-turn encoder.
  • the magnetic absolute encoder or rotary encoder operates in particular after the magnetoresistive or after 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, 4 or 6 Hall sensors.
  • An intelligent evaluation electronics e.g. based on DSP, allows a unique detection of the entire full circle.
  • 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 gearless drive is a high temporal resolution even at low speeds possible. 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 development, which is characterized by very good concentricity properties with low noise levels.
  • the angle encoder in the axial direction an extension of max. 40 mm, preferably of max. 20 mm.
  • the angle encoder is mounted coaxially with the motor shaft.
  • the electric motor is preferably designed as a, in particular permanently excited, synchronous motor.
  • the length of the electric motor - measured without any bearings, drive pinion and electronic components - less than 60 mm, in particular less than 36 mm.
  • the length of the electric motor - measured at a distance of at least 35 mm from the shaft and without any bearings, drive pinion and electronic components - less than 60 mm, in particular less than 36 mm.
  • the diameter and / or the edge length of the electric motor preferably lies in the range between 50 mm and 200 mm, preferably in the range between 80 mm and 160 mm.
  • the electric motor 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 in the range of 3.0 Nm to 4.5 Nm, preferably from the Range from 3.5 to 4.0 Nm.
  • a drive pinion or pulley for driving the belt or the chain is mounted on the shaft of the electric motor.
  • a transmission would significantly increase the axial extent of the overall system of electric motor and transmission compared to a gearless drive.
  • the space would also increase because the driving force would first have to be transmitted from the motor shaft via the countershaft to a non-axially located double pinion, which in turn drive only the chain or the belt.
  • Gearlessness also means lower losses and noise.
  • the drive pinion or pulley is in particular attached to a freestanding end of the shaft. This results the advantage of universal integration into the door system.
  • the electric motor - 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 electric motor 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.
  • the motor is mounted such that its shaft is perpendicular to the opening and closing direction of the door and / or aligned horizontally. This is a particularly compact and with respect to the driving force deflection-free and thus low-loss arrangement possible.
  • 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, up.
  • 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 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 electric motor - 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.
  • angle sensor is mounted on the side facing away from the drive pinion or pulley side of the electric motor.
  • a total length of electric motor, drive pinion or pulley and angle encoder in the shaft direction of less than 110 mm, preferably less than 98 mm, appropriate.
  • FIG. 1 shows an automatic 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.
  • 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.
