Answer Posted / rajeshsan
salient pole machines driven by water turbines at a speed in the range 50 ±1000 rev/min. Generally used for low speed applications. The speed depends on the type of turbine,which in turn depends on the head and the flow rate of the water available. At low speeds, the permissible rotor diameter will be several times its active length. Generally,the largest allowable diameter of rotor is used to maximise the machine's inertia which is an important part of overing the water turbine. Outputs up to 800MW have been achieved. A small high-speed unit will have a horizontal shaft, but for reasons of mechanical construction and stability larger machines have vertical shafts.
