High-Power Alternator for robotic weed eliminator ROBOVATOR

Project details and scope of services

This machinery is illuminating ground and plants and films them. Weed is identified by computerized self-learning artificial intelligence and robot arms eliminate any weed mechanically.

This highly computerized technology requires a stable power source capable of delivering high power to robotics, computers and illumination. The first prototype therefore used multiple parallel-connected standard alternators plus some heavy 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
