A MEMS thermal actuator device is provided that is capable of providing linear displacement in a plane generally parallel to the surface of a substrate. Additionally, the MEMS thermal actuator may provide for a self-contained heating mechanism that allows for the thermal actuator to be actuated using lower power consumption and lower operating temperatures. The MEMS thermal actuator includes a microelectronic substrate having a first surface and at least one anchor structure affixed to the first...

An electronic switching electric motor having a rotor and a stator having a number of stator teeth is characterized in that an assembly element of stator teeth is made of plastic and is co-molded with the stator teeth. The electric motor has two support seats for the rotor, where at least one of the support seats is present in the assembly element.

A wind power motor comprises a rotor drum having a circumferential drum wall forming an open air inlet end and an open air outlet end. The drum wall has a wing profile-like axial cross-section, so that the drum wall is thicker at the air inlet end than at the air outlet end. A plurality of vanes are attached to the rotor drum. Each vane has a front end and a rear end, which is displaced in the circumferential direction of the rotor drum relative to the front end, so that the vane acts on the rot...

A rotor (10) for an electric machine (40) includes a first elongated rotor segment (12) having a plurality of axially extending rotor poles (20) arranged in a circular array about a central axis (18) that extends longitudinally through the first rotor segment(12). A second axially extending rotor segment (14) engages and is fixed relative to the first rotor segment (12). The second rotor segment (14) has a plurality of axially extending rotor poles (38) arranged in a circular array about the cen...

A cooling gas ventilation circuit for an endwinding of a rotary machine having a rotor and a plurality of coils seated in radial slots provided in the rotor, the coils each comprising a plurality of radially stacked turns, the turns having radial passages therein, the coils extending beyond a pole face of the rotor to form an endwinding; a substantially cylindrical baffle ring covering radially innermost turns of the plurality of coils in the endwinding, the baffle ring having a plurality of hol...

A self-propelled wind power regenerator powered by the natural wind, by a propeller or a combination of both, depending on the condition of the wind and the demand of the electricity. During the period when the natural wind flows constantly above the cut-in wind speed, the wind turbine may be powered by the natural wind. When the useable natural wind becomes unavailable, the propeller is activated by a sensor that detects the drop of the output of the wind turbines. The propeller thus keeps the ...

A wind power installation with a rotor, a generator for generating electric power, at least one rotatably mounted rotor blade displaceable about its longitudinal axis for adjusting the angle of attack, and an auxiliary generator for generating electric power for at least one consumer, characterized in that the auxiliary generator produces electricity for a controller for the rotor blade adjustment and for a drive for adjusting the angle of attack of at least one rotor blade at a lower range of r...

Oceanic tidal energy sources hydroelectric generating system coupled to a primary tidal basin through a bi-directional tideway exciting a turbine as a diurnal cycle tide waxes and wanes. A secondary tidal basin includes a tideway and turbine with flow modulated by a regulator gate to proportionately blend reserve tidewater capacity of the secondary tidal basin as a delayed resource compensating a slacking of the primary tidal flow with a graduated secondary tidal basin influx or outflow providin...

A computer peripheral system includes a computer peripheral and a mechanical input device adapted to initiate a conversion of mechanical energy to electrical energy. The computer peripheral includes an energy conversion device adapted to convert mechanical energy to electrical energy. The converted electrical energy provides power to at least one computer peripheral component.
