Most wind turbines (WT) are of the single-rotor type, which means they are simple, reliable
and durable, but unlikely to convert more than 40% of the available wind energy. Different …

A specific topical issue both for small hydropower plants and wind turbines refers to the
discrepancy between the relatively low speed of the water turbine/wind rotor and relatively …

The paper deals with a new variant of a cycloidal planetary transmission (CPT) with modified
structure, proposed by the authors, able to accomplish high kinematical ratio and high …

The paper presents the dynamic modeling, in a simplified approach, of a new variant of
planetary cycloidal reducer with a sun gear, proposed by the authors; the reducer is …

Cycloid reducers compared with classical reducers have low axial and radial gauge, high
transmission ratio, and a better reliability. Cycloid gearing roller, through its qualities, has an …

Many of the renewable energy systems (RES) use planetary gears for the speed increase or
reduction. The paper presents a 2 DOF planetary gear transmission to be used as “speed …

Mechanical power transmission by reducing the rotating speed under a constant
transmission ratio represents the function of a large group of products known as speed …

In order to comply with the 20-20-20 Directive, by which every EU member state has
pledged to produce 20% of the energy by using renewable sources, solar energy for heating …

In order to capture as much solar energy as possible, the photovoltaic converter has to
follow the sun movement during a day; this can be achieved by a tracking system. Most …

Based on a comparative analysis of the conceptual design algorithms proposed in literature,
a new variant of the conceptual design modeling, whose algorithm generalizes the existing …
