Machine throughput and production rate is a key factor for efficient manufacturing. It is well known that building machines that move back and forth result in lower efficiency than unidirectional movements.
The new solution for a closed track transport system delivers many advantages over moving magnet transport systems. Accuracies in this solution are higher compared to moving magnet transport systems. The response time is considerably better because there are no issues with latency due to direct feedback of the encoder to the drive. They also allow to have a sinusoidal commutation instead of complex commutation profiles and have an easy control due to the moving coil setup. Finally the cost per meter is significantly lower.
The track can be made in several shapes having multiple kind of solutions, like oval, circular and square with curved corners. The possibilities are endless.
Applications can be found in packaging, but also in factory automation, assembly stations, digital printing, lab automation, hexapods, systems in need of a pitchless conveyor design and applications with no human interference.
The curved magnet plates have a smart design that compensates for force losses in the curves due to commutation error, which occur due to straight coils on curved tracks. The motors have a low attraction force in respect to their continuous force exerting in low wear on the bearings. The motors also have low cogging which gives in combination with the cogging compensation algorithm a very smooth motion in the curves. Tecnotion is able to deliver up to 2000N of continuous force depending on diameter.
A new technology now allows machine designers to benefit from the dirt immunity and mechanical tolerances of the magnetic technology without the need to compromise on measuring accuracy. The motion control solution fully supports on-the-fly switching from analogue hall feedback to linear encoder feedback, while maintaining the same engineering units defined by the user regardless of the feedback in use.
