High torques at low speed

Drives for trackers in solar power plants require robust drive systems with high accuracy, efficiency and virtually maintenance-free long-term operation showing a high degree of reliability.Präzisionsdrehwerksgetriebe von AUMA Drives / GFC

Only components specially designed for outdoor use can meet these requirements.
