20140291988 | Electric Generator - An electric generator (1) for the conversion of energy from a renewable energy source, such as wind energy, into electrical energy to be inserted into a local or remote network (R), which comprises a rotary electric machine (2) provided with means (3) for drawing energy from the renewable source and for converting into electrical energy, first control means (4) for regulating the functioning parameters of the machine (2), second control means (5) for regulating the parameters of the electrical energy generated by the machine (2), and connection means (6) for electrically connecting the second control means (5) to the network (R), wherein the machine (2) is positioned in a space (V) placed at a predetermined distance (h) with respect to a base (B) that is fixed or anchorable with respect to the ground (T). The first control means (4) are housed in a first case (7) placed inside the space (V), the second control means (5) are housed in a second case (8) that is different and spatially offset with respect of the first, and the second control means (5) are electrically connected to the first control means (4), to facilitate the mounting and the maintenance of the generator. | 10-02-2014 |
20140239858 | Movement control system for a drilling plant - A movement control system for a drilling plant includes a first hydraulic circuit with an inlet duct and an outlet duct for a working fluid, a pumping device of reversible type promoting the circulation of the fluid, first electric machine mechanically coupled to the pumping device to promote circulation of the fluid in the first hydraulic circuit, wherein the first electric machine is connected to an electric circuit connectable to the net or to an electric accumulator. The first electric machine selectively operates as an electric motor to promote circulation of the fluid in a first sense and to drive the actuating means during the rise of the drilling head, and as an electric generator upon fluid flow in a second, opposite sense during the lowering of the drilling head to inject in the network or in the accumulator the electric power generated by the first machine. | 08-28-2014 |
20140035402 | Electric Generator - An electric energy generator includes a driving shaft designed to be coupled to an external energy source having a predetermined torque, a synchronous reluctance rotating electric machine having a stator and a transverse-laminated rotor, and a driven shaft operatively coupled to the drive shaft for generating electric energy with a predetermined torque ripple amplitude, an electric connection for injecting the electric energy so generated into the net, a control system designed to adjusting electrical and dynamic parameters of the electric machine. The stator has an even number of longitudinal grooves for each pair of poles and the rotor has a plurality of adjacent slots defining an even number of magnetically equivalent slots. The number of grooves is different from the number of equivalent slots multiplied by an integer, the difference between the number of grooves and the number of equivalent slots being different form zero, +2 and −2. | 02-06-2014 |
20140022727 | Cooling device for electronic components and control apparatus comprising the cooling device - A cooling device for electronic components includes a substantially prismatic body made of a thermally conductive material, which has a pair of substantially planar main outer surfaces and encloses therein at least one circuit for the flow of a cooling fluid. Both main outer surfaces are designed to allow removable attachment of an electronic component to be cooled. A control apparatus incorporating the device. | 01-23-2014 |
