400W Vertical Axis Wind Turbine Test Bench

The 400W Vertical Axis Wind Turbine Test Bench, developed and supplied by Atto Labware India, is a high-capacity educational and research trainer designed for renewable energy laboratories, universities, and R&D centers. With a low start-up wind speed of 2 m/s and 360° omnidirectional wind capture, it effectively demonstrates wind-to-electricity conversion. Equipped with a three-phase permanent magnet generator, electromagnetic brakes, and an integrated control system, this turbine enables detailed performance testing under varying wind and load conditions, making it ideal for hands-on learning, lab experiments, and hybrid energy applications.
