Web14.5.2 Smooth cylindrical or non-salient type rotor. Such rotors are used for high speed alternators. The rotor is made of steel cylinder with number of slots cut on the periphery of the cylinder. The field windings are placed in the slots. The chart area acts as the pole. These axial alternators have more length and smaller diameter. Web16 Oct 2024 · If a smooth cylindrical rotor was considered in the case of the initial design, this improvement would be lower. Nevertheless, efficiency was improved by 18.5%. This improvement was achieved by further reducing windage losses by reducing the rotor diameter, but also by reducing iron losses by selecting more suitable material. ... The cylindrical rotor has smooth surface because there is no poles projected on it. Hence, it maintains a uniform air-gap between the stator and rotor in the alternator. The cylindrical rotor synchronous generators are usually driven by steam turbines and mostly used in very high speed applications such as turbo … See more When the rotor of a synchronous generator has non-salient pole or smooth cylindrical construction, the generator is called cylindrical rotor synchronous … See more When the synchronous generator uses a projected pole type rotor, it is known as salient pole rotor synchronous generator or salient pole alternator.
