4000W Vertical Axis Wind Turbine Test Bench

The 4000W Vertical Axis Wind Turbine Test Bench, developed and supplied by Atto Labware India, is a high-power educational and research trainer designed for universities, R&D centers, and advanced renewable energy laboratories. With a low start-up wind speed of 2.5 m/s and full 360° omnidirectional wind capture, this system demonstrates large-scale wind-to-electricity conversion. Equipped with a Maglev generator, electric eddy brake control system, and a robust test bench, it allows detailed performance analysis under varying wind and load conditions. Ideal for hands-on experimentation, hybrid energy studies, and high-capacity wind energy research.
