  • Tor Gayselement For driving gates such as garage doors, garden gates, hall doors or large industrial doors electric motors are regularly used, the drive via an output shaft a Tor Gayselement, usually a door shaft to wind, for example, a goal rope or a Torkette on which the gate is attached. It is understood that other Tor Gaysetti can be used here.
  • the invention is therefore based on the object to present a cheaper way to drive a gate.
  • a refinement of a door drive according to the prior art should be achieved with simple means.
  • a device for a door drive in particular for a sectional door, roller shutter or the like, with a Torterrorismselement, in particular a Torwelle, for opening and closing a gate and a Torterrorismselement arranged on the connecting means, wherein the door drive comprises at least two electric motors, of which a fixedly connected to the Torterrorismselement (2) connecting means is indirectly / directly connected and all other electric motors (3,4) are arranged radially movable around the Torschulselement and connected thereto via the arranged connecting means.

It is important here that the drive torques of the individual electric motors are not oppositely directed but interact with one another. This is a large, expensive unit can be replaced by two smaller, or cheaper standard electric motors.
  • a rolling grill can be arranged on the door shaft so that the rolling grill is wound up or unwound in the case of a rotational movement about the longitudinal axis in the clockwise or counterclockwise direction.
  • the winding movement is generated by the electric motors, which are connected via connected to the engine output shaft connecting means with the arranged on the Torwelle connecting means whose torques are rectified and put the Torwelle in the corresponding rotational movement.
  • all further electric motors are arranged so as to be radially movable around the door-moving element, whereby transformer and motor differences and thus asynchronous operation of the at least two electric motors can be compensated. Run the speeds, or drive speeds of the at least two electric motors apart, i. asynchronous, an ideal power transmission is no longer secured and there are additional friction points at certain points of the connecting means of the door drive. As a result of the movable arrangement of the further electric motors used, such additionally occurring friction points can be compensated for asynchronous drive speeds of the motors and the unimpeded transmission of power of the individual motors to the door moving element can be ensured.
  • the flanged to the motor output shafts connecting means comprise a drive pinion, which engage in a suitable arranged on the Tor Gayselement connecting element and about this move the Torterrorismselement in motion.
  • the connecting means arranged on the door moving element is a chain or a further toothed wheel arranged on the door moving element.

  • At least one transformer is provided in the door drive, which is connected with at least one or all electric motors such that the required supply voltage for the electric motors can be provided.
  • the transformer can, for example, transform the AC voltage present at the input to a required effective value and generate a DC voltage at the output by means of a downstream rectifier.
  • At least one electric motor comprises a DC motor.
  • DC motors can be controlled via a relatively simple circuit structure of a controller. This results in a simplified control of a DC motor over known AC motors, as can be dispensed with the necessary frequency to operate a regulated AC motor. As a rule, such known DC motors have very high output speeds.
  • At least one electric motor comprises a geared motor.
  • a geared motor in its geared motor housing on a motor unit with a downstream small transmission.
  • the gearbox With the gearbox, the high output speed can be transformed down in DC geared motors and a higher output torque is produced at the output of the motor at a lower speed.
  • At least one manipulated variable in particular a Tor einssignal, by a suitable means on the door drive can be detected and the manipulated variable is used to control the supply voltage of at least one electric motor.
  • the speed or the rotational speed of the respective interconnected electric motor can be controlled by the voltage U.
  • the door position signal indicates, for example, the respective opening position of the door used and causes braking, stopping or accelerating the door drive.
  • At least two transformers supply the at least two electric motors with a required supply voltage.
  • a transformer is connected in each case with an electric motor and supplies it with a required supply voltage for operation of the electric motor.
  • At least one motor is resiliently arranged or mounted on the door drive via at least one spring, whereby transformer and motor differences and thus asynchronous operation of the at least two electric motors can be compensated.
  • the at least two motors are connected via the connecting means with the Tor Gayselement that their output torques cause a drive of the Tor Gaysiatas.
  • the connection is designed so that an ideal power transmission can be achieved. Do the speeds, or
  • At least two incremental encoders are arranged on the at least two electric motors and, based on the measured values detected by the incremental encoders, a controlled variable for controlling at least one electric motor can be determined.
  • Incremental encoders are sensors for detecting changes in position which can detect both distance and direction. By arranging each of an incremental encoder on each of an electric motor, the distance covered by each individual electric motor can be determined and is thus suitable for an evaluation of the rotational speed of the individual electric motors. By a suitable signal evaluation deviations of the electric motors of a mutually synchronous operation can be determined and by means of the controlled variable is at least one electric motor so regulated that the operation of the individual electric motors is synchronized with each other again.
  • the controlled variable influences the supply voltage of at least one electric motor in such a way that its rotational speed can be adapted to the rotational speed of the other electric motors used. It is conceivable that not only an electric motor on the detected controlled variable is regulated, but a control of several electric motors based on the control variable.
  • the controlled variable can be determined by comparison or addition of the abovementioned measured values of the incremental encoders and at least one electric motor can be regulated by means of this controlled variable.
  • the addition or the comparison of the measured values can be carried out via appropriately interconnected operational amplifiers.
  • the door drive provides at least one measuring device for measuring the angular position of at least one electric motor arranged on the door drive.

  • the door drive provides at least one sliding resistance, which is arranged such that the supply voltage is variable at least one electric motor directly by the sliding resistance.
  • the supply voltage is variable at least one electric motor directly by the sliding resistance.
  • the applied supply voltage can be varied directly via the sliding resistance of the respective electric motor and thus a synchronous operation of the individual electric motors is mutually adjustable.
  • the door drive provides a controller for the evaluation and control of the manipulated and / or controlled variables.
  • the controller processes and evaluates the measured values measured in order to realize an activation of the at least two electric motors in such a way that a synchronous operation of the at least two electric motors is ensured with one another.

  • the controller outputs a manipulated variable 8, which is responsible for controlling the supply voltage of the two electric motors 3.4 FIG. 1 serves. Based on the supply voltage, the speed with which the two electric motors 3,4 rotate can be varied.
  • both the electric motors 3.4 supplying supply voltages are controlled by the manipulated variable 8. Since even with the use of identical electric motors 3,4 and transformers 7 result in minimal differences in their performance characteristics and this leads to a slightly asynchronous operation of the two electric motors, an electric motor 4 is arranged via springs 9 on the door drive.
