摘要:
Apparatuses and methods are provided for facilitating air-cooling of, for instance, one or more electronics racks within a data center. The apparatus includes an air-moving assembly and one or more flywheels. The air-moving assembly includes a shaft, one or more mechanical fans coupled to the shaft to rotate, at least in part, with the shaft, and a motor coupled to the shaft to rotatably drive the shaft. The flywheel(s) is sized and coupled to the shaft of the air-moving assembly to store rotational energy, and to facilitate, for a specified period of time, continued rotation of the shaft during interruption in power to the motor. In one implementation, the flywheel(s) is sized and coupled to the shaft to facilitate, for the specified time period, continued rotation of the shaft at a specified percentage, or greater, rotational speed of the shaft compared with shaft speed when rotatably driven by the motor.

摘要:
A method of mounting elements in a wind turbine tower, whereby the elements are partly or completely attached to the wind turbine tower by means of magnetic attraction forces. Wind turbine suspension units may be attached to the wind turbine tower, preferably completely or partly to the inner wall by means of magnetic attraction forces, which present structure-weakening attachments to the tower or part of the tower.
摘要:
A wind turbine having one or more magnets for reducing friction between the turbine support and a turbine rotor. The reduction of friction between the turbine rotor and the turbine support allows for an increase in energy production and scale of the wind turbines. The magnet configuration employs a ring of cylindrically-shaped magnets at the bottom and opposed by a corresponding number of generally rectangular-shaped magnets. Bearing magnets are also employed for axial stabilization.

A wind turbine blade transversely divided in an inboard module (13) and an outboard module (33) provided on their end sections with connecting means, comprising, respectively, an inboard spar (15), an inboard upper shell (17) and an inboard lower shell (19); an outboard spar (35), an outboard upper shell (37) and an outboard lower shell (39); and arranged so that the aerodynamic profile of said inboard and outboard modules (13, 33) is defined by said upper and lower shells (17, 19; 37, 39), in which the inboard spar (15) is composed of two cap prefabricated panels (21, 23) and two web prefabricated panels (25, 27), and the outboard spar (35) is composed of first and second prefabricated panels (41, 43) integrating its caps (45, 47) and webs (49, 51). The invention also refers to a method of fabricating said wind turbine blade.
摘要:
A wind turbine having a tower and at least one radar-absorbing panel attached to an outer surface of the tower is described. The panels are attached by mounts that do not penetrate the outer surface of the tower. In preferred embodiments of the invention, the mounts attach magnetically to the outer surface of the tower.
摘要:
A magnetic piston shoe pair for an axial piston pump and the motor includes: pistons, coil suites, piston shoes and a swash plate, wherein the interior of the coil suite is a closed coil; the bearing surface that the end surface of the swash plate abuts the piston shoe is provided with micro-molding holes; the micro-molding holes are hemispherical; the back surface of the swash plate is provided with a primary iron core and two secondary iron cores; the iron cores are wound with coil; the coil is connected to an external alternating current power supply. When the pump/motor is working, the coil is energized to generate a magnetic field, thereby adsorbing the piston shoe on the swash plate. Meanwhile, the coil suite generates an inductive magnetic field.
