- the present invention is based on the idea of heating the engine environment by generating heat loss of the electric motor when the closing holding force is generated, as a function of the measuring temperature of the temperature sensor. The colder this measurement temperature, the greater the amount of heat loss generated, at least within certain limits. If the measuring temperature increases again after a respective cooling of the temperature sensor, the control device can also reduce the electrical power of the electric motor again in order to achieve the most economical possible operation of the electric motor.
- Temperature-sensitive elements of the drive device should be thermally coupled sufficiently well to the electric motor in order to benefit from its waste heat.
- the electric motor and other components of the drive device are accommodated in at least one cavity of the housing, for example in a door latch forming the housing.
- the housing should be thermally insulated, so that the waste heat supplied by the electric motor is stowed within the housing area as efficiently as possible in order to heat existing temperature-sensitive components of the drive device and thus to keep it at favorable operating temperatures.
- the control device is configured to vary the closing holding current to be provided for generating the closing holding force of the electric motor to control the electric power of the electric motor depending on the respective temperature information of the temperature sensor, so that the closing hold current of the electric motor decreases with decreasing measuring temperature of the temperature sensor increases at least from below a certain measurement temperature - and the closing hold current of the electric motor at how- the rising measuring temperature decreases again.
- the electric motor may, for example, be a low-voltage DC motor operating at an operating voltage in the range from 12 to 50 V, for example 24 V. The currents used here for generating heat loss of the electric motor can be controlled at these low voltages.
- DC motors are suitable as electric motors for the invention, but also AC and three-phase motors adapted to effective voltage.
- the electric power to be provided for the generation of the closing holding force of the electric motor may be variable in a range between 40 W and 120 W according to an embodiment of the invention.
- the closing holding current to be provided for the generation of the closing holding force of the electric motor may be varied in a range between 1.5A and 10A.
- the control device is preferably configured to maintain the closing holding current of the electric motor at a substantially constant value if the measuring temperature of the temperature sensor exceeds a specific limit value. In this way it is achieved that at uncritical temperatures of the drive means an energy-saving Elektromotor memori operation with low heat loss is possible.
- the at least one temperature sensor is arranged on the electric motor and accommodated with this inside a door damper.
- the temperature of the electric motor can be continuously monitored and regulated in the sense of the present invention to a favorable desired value or to a favorable desired value interval.
- the temperature sensor may also be provided elsewhere, for example outside the automatic door, for example to detect the ambient temperature, so that the control of the power supply to the electric motor takes place in dependence on the outside temperature.
- both a temperature sensor provided on the electric motor and at least one further temperature sensor, such as an outside temperature sensor, are provided and in data transmission connection with the control device, so that the control device takes into account the measured values of both temperature sensors in the control of the electric motor ,
- a car door of an elevator may be mentioned.

- FIG. 2b shows a sectional view of the sliding door from FIG. 2a corresponding to the sectional plane bb in FIG. 2a.
- the automatic sliding door shown in the figures is a telescopic sliding door with a frame and a door leaf assembly of two door leaves 3, 5, which are aligned parallel to each other during the opening operation and the closing operation of the telescopic sliding door in two parallel sliding planes E3, E5 and horizontally along each other Move guide rails.
- a drive device 7 serves to open or close the telescopic sliding door at the request, for example at the push of a button, wherein the door leaf positioned to the right in FIG. 1 b and positioned in the slightly displaced sliding plane E 3 according to FIG. 1 b moves faster than in FIG
- the door leaf trailing in the direction of opening movement and leading in the direction of closing movement is usually displaced at approximately twice the speed as the other door leaf.
- the two door leaves 3, 5 have orthogonal to the shift planes E3, E5 a small distance from each other, so that they can be moved without mutual contact along the shift planes E3, E5 in the closed position shown in Figure 1 a and in the open position 2a.
- the automatic operation of the door is under control of an electronic control device 25 which is housed together with the drive means 7 in a cavity 24 of the door damper 26.
- the control device 25 generates control and switching commands for an electric motor 27 in order to provide it with controlled electrical drive energy and to specify the respective direction of motor rotation.
- the door leaves 3, 5 move in the opening movement direction or in the closing movement direction.
- the door drive device 7 shown greatly simplified in the figures is a cable drive in which the electric motor 27 drives a deflection roller 31 via a transmission belt 29 or the like to the right above the door opening 4, the deflection roller 31 concentric with one another about the deflection roller axis arranged cylindrical Umlenkrollenabête 33, 35, of which the Umlenkrollenabough 33 has a larger diameter than the Umlenkrollenabrough 35.
- Each of the two Umlenkrollenab- sections 33, 35 is looped by a respective Endloszugseil 37, 39 and serves for its drive and deflection.
