3. PHASE I - CONCEPT DESIGN & PRELIMINARY TESTING
The new windpump is innovative in having a form of epicyclic rack transmission mechanism that produces a quasi-constant torque load (combined with speed reduction) which addresses the start-up problems common to conventional crank driven windpumps. Crank-machines demand significantly higher wind speeds for starting than to keep the system running due to the fact that the starting torque requirement is in the order o f 300% o f the mean running torque.
