TESTING

Initial testing of the generator was performed in the laboratories of the Provincial Engineering & Technology Centre of Electrical Vehicles in Jiangsu (China), with subsequent tests in the laboratories of the UNSW, Sydney. Testing of composite materials (static and fatigue) was performed at UNSW Sydney. The results have been used in the design to ensure static and fatigue strength.
