High-Power Alternator for robotic weed eliminator ROBOVATOR
The ROBOVATOR built by KRESS Umweltschonende Landtechnik eliminates weeds without use of chemicals.
Project details and scope of services
This machinery is illuminating ground and plants and films them. Weed is identified by computerized self-learning artifical intelligence and robot arms eliminate any weed mechanically.
This highly computerized technology requires a stable power source capable of delivering high power to robotiocs, computers and illumination. The first prototype therefore used multiple parallel-connected standard alternators plus some haevy lead-acid car batteries causing an instable power supply.
We were able to replace this heavy and maintenance-intensive setup with only ONE D*Star-Alternator, driven by the machinery driveshaft from the tractor.
The challenge was especially to cope with the low RPM level and high power requirements. Due to its low kick-in RPM and steep power curve our D100-17102 was the ideal solution.
Our Contribution:
- Selection, System Design and Calculation of the Alternator
- Delivery of the D*Star High-Power Alternator supplying 14V / 350A / 4,9kW
