Abstract: An arrangement of a magnet-based rotational angle measuring system on a drive motor housing part. The arrangement includes the drive motor housing part, a drive shaft with a free end which extends out of the drive motor housing part, an exciter unit connected to the free end of the drive shaft to rotate therewith, a stationary sensor unit which cooperates with the exciter unit to detect a rotary movement of the drive shaft, a shielding body arranged between the stationary sensor unit and the drive motor housing part, and an alignment element which directly aligns the stationary sensor unit with respect to the drive motor housing part.

Abstract: A magnet-based angular displacement measuring system for detecting a rotational movement of a driveshaft. The magnet-based angular displacement measuring system includes the driveshaft which includes an axial first shaft end region. The axial first shaft end region includes a magnetically non-conductive material. An exciter unit is rotationally coupled to the axial first shaft end region of the driveshaft. A stationary sensor unit functionally cooperates with the exciter unit to detect a rotational movement of the driveshaft.

Abstract: A drive arrangement for a door device which includes a door member. The drive arrangement includes a door shaft, a driven shaft which is operatively connected to the door shaft, a transmission arrangement which drives the door shaft, and at least one electric motor which is coupled to the transmission arrangement to move the door member of the door device from a closed state to an open state and vice versa. The at least one electric motor has at least one eccentric drive shaft. The transmission arrangement includes an eccentric gear transmission which has at least two orbiting toothed disks, each of which have an internal toothing. The at least two orbiting toothed disks are driven by the at least one eccentric drive shaft of the at least one electric motor, and, via the internal toothing, engage with the driven shaft.

Abstract: A magnet-based angular displacement measuring system for measuring a rotational movement of a driveshaft. The magnet-based angular displacement measuring system includes a drive shaft comprising a free end. The free end has a coaxial recess so as to form a hollow shaft section. An exciter unit is rotationally coupled to the free end of the drive shaft. A stationary sensor unit functionally cooperates with the exciter unit to measure the rotational movement of the drive shaft.

Abstract: A maintenance system for a gate device includes a controller, at least one temperature sensor, and an evaluation unit. The controller has a motor control unit which actuates a drive apparatus for driving a gate member, and a non-volatile memory which stores gate data. The gate data is retrievable from the non-volatile memory. The at least one temperature sensor is arranged in a region of the drive apparatus. The at least one temperature sensor continuously transmits a detected temperature as further gate data to the non-volatile memory of the controller. The evaluation unit creates a temperature curve for each of the at least one temperature sensor over a preset operating cycle. A comparison of more than one temperature curve allows a conclusion to be drawn of a need for maintenance of the gate device.
