JAT engineers connect specific sectors and process knowledge with unique technology expertise - for a cost-efficient, high-tech, ready-to-connect drive solution.
To realize the ever-increasing requirements towards precision, our application-specific solutions use a diverse ranges of technologies, e.g. air bearings and magnetic bearings. Our interdisciplinary drive expert teams further research and develop a SCARA robot - a cost-efficient jointed-arm robot - and a technology for momentum compensation in positioning systems. It is our goal to always develop and design a perfectly fitting solution to our customers' requirements.
In the manufacturing sector, drive monitoring systems are only used for limit value monitoring and to ensure machine operability. However, information such as current, speed, position, the corresponding setpoints and manipulated variables in the controller cycle of the servo inverter are hardly used, but have a high potential for deducing statements about process quality, safety and robustness. On the one hand, there is currently still a lack of targeted, algorithmic compression into technically meaningful smart data. On the other hand, there is a lack of connection between separately recorded sensor data and decisive meta-information, e.g. a device‘s history.
Therefore the project aims to make accessible the already existing operating data of servo inverters (SU) installed in drive components and process them through Prony analysis in order to develop a condition monitoring system for mechatronic drives for mask production plants. Thus, it is possible to infer the operating states of the drives without the aid of external sensors, assign process and machine deviations to their causes, record process parameters at 100µs intervals and to adjust them if necessary, to ultimately increase machine efficiency.
ImPosAnt is a development project together with the Technical University of Dresden. It is our objective to develop a momentum compensated positioning drive system.
Supported by the Central Innovation Programme for small and medium-sized enterprises of the Federal Ministry for Economic Affairs and Energy, we work towards implementing the momentum compensation technology into the JAT servo amplifiers. It is developed and patented by the Technical University of Dresden.
- Requires no additional hardware
- Solution integrated into servo amplifiers
The LinearPipes funding project will start on 1st September. JAT’s cooperation partner is the Technical University Cologne, specifically Prof. Dr. Jörg Luderich at the Institute for Product Development and Design Technology within the Faculty of Plant, Energy and Machine Systems.
In linear direct drives, high amounts of heat are released by strong acceleration and braking processes with simultaneous high loads, resulting in the need for a cooling system. The aim of the project is to develop a heat-tube-cooled linear direct drive with an intelligent temperature control system. The cooling system should function without the periphery of water cooling systems, which have been necessary until now. This leads to a clear advantage in terms of handling and costs. The temperature control (targeted additional heat-input) is also intended to increase the accuracy and service life of the drive windings.
Air bearing motion systems position workpieces free of friction, stick-slip and without material wear, making them especially applicable for clean room applications. Air bearings function through a thin air layer between the bearing components, enabling stick-slip-free motion. therefore, the technology is perfectly suited for precision machinery. Air bearing technology allows us to realize rotatory and linear motion with repeatability <100 nm.
- Frictionless, stick, slip and wear-free
- For high spends and very rapid accelerations
- No oil or other lubricants required
- Self-cleaning with air pressure in dusty environments
- For noiseless and frictionless operation
- Clean room compatible
A great alternative for performing flexible positioning and handling jobs is the jointed-arm robot developed by JAT. The special feature of this solution is the gripper platform, which always moves parallel to the reference plane while being independent of its position in the room.
The jointed-arm robot stands out due to its modular, cost-efficient design and can be flexibly scaled for a wide variety of tasks.
- Gripper platform always moves parallel to the robot table
- Layout based on the modular principle
- High flexibility level in the movement range
- Cost-efficient design (use of standard profiles and components)
- Highly dynamic due to drive unit integration into base frame
- 3 drive units allow for free motion through 3D space
We developed a linear actuator for dynamic focus adjustment to meet the ever-increasing requirements of the laser processing industry. The current model has a 43 mm hollow shaft diameter. This setup allows for usage of optical lenses in this size as well as reducing the moving mass. Using an optimized magnetic system the actuator reaches acceleration up to 60 G and a 10 ms adjustment time over the 4 mm maximum stroke length - while still being very energy-efficient.
Laser-processing requires repeatability and reliability through many operating cycles. These requirements are perfectly met through use of no-maintenance stick-slip-free flexure hinges and our in-house developed linear measuring system with 64 nm resolution. Combining the actuator with JAT servo amplifiers enables the system to reach 1 µm accuracy and minimal positioning times.
Wear-free, stick-slip-free, no maintenance
Suitable for high velocites and very high accelerations
No lubricants necessary
Large aperture enabling high laser output
The compact JAT SCARA robot is particularly well-suited for extremely precise handling jobs, assembly tasks as well as pick & place and testing applications. All four axes are directly controlled due to its special kinematics, . X-Y-Z axes are rotating axes; the Z-axis also acts as a stroke axis. With a repetition precision of ±1 micrometre and its compact, robust design, the JAT SCARA is an ideal starter model for precision robotics. The SCARA stands out due to its extraordinary flexibility. The JAT drive experts design the SCARA robots with varying strokes depending on the customer application.
- High precision due to directly-driven stroke and Z axes
- Tried-and-tested unit – 4 engines controlled by two ECOVARIOs 114D
- Compact, space-saving dimensions
- Z axis – rotating axis + stroke axis
- Customizable design, scalable stroke
Attenuation of machine elements through vibration isolation is becoming a more important technology as technological progess keeps pushing the industry sectors forward. Many high-precision applications require effective oscillation decoupling so that external impacts to the system do not negatively affect motion precision.
To decouple oscillations, force-transmitting components must be designed to be as flexible as possible and installed between the bodies. As long as there is a solid body connection however, one can still observe a frequency-dependent attenuation behaviour. Even active oscillation decoupling cannot fully eliminate these properties, as this counteracts the interference signal and the control fault, which cannot be fully eliminated, which in turn results in minor interference signals.
That is why we develop bearings with as little rigidity as possible that function completely without body contact in order to decouple a system from the environment as ideally as possible. In addition, the rigidity of these bearings can be modified so that momentum that arises within the borne mass can be intercepted without having to tolerate very large movement ranges for the bearing points.
The functionality has been proven with a magnet bearing-based prototype for a load range of up to 600 N. We can realise special customer requirements based on the existing, scalable prototype.
- Consistent effectiveness throughout the machine’s entire service life
- Reduction of wear
- Significant reduction of structure-borne sound
Where does innovation take place? Only in rare cases real innovation rises up in single mind. Much more often, innovation is the result of a joint effort towards finding a solution to a problem that is unsolvable with current methods. Research is exactly that. Interdisciplinary teams of experts join forces to realize what was considered impossible. This not only requires clever people, but also highly reliable laboratory instruments for executing tasks. As a specialist for high-precision motion systems, JAT cooperates with institutes and research facilites in developing sub-micrometer range positioning solutions to enable their research progess.
