20110148116 | Antenna Mounted Wind Power Generator - A cellular communication tower is adapted to support a vertical axis wind turbine (VAWT) that includes a generator mechanism. The signal and power cable for the communication antennas run through the central axis or bore of the generator. The blades of the VAWT are disposed so as to avoid interferences with communication signals. The tower preferably deploys an open truss construction to avoid the impact of periodic pressure pulse as the turning blades shift out of alignment from shading the tower. Thus, with an open truss tower the turbine blades can be a larger size and still not cause such pressure pulses. | 06-23-2011 |
20090200890 | Winding For An Axial Gap Electric Dynamo Machine - The stator of an axial gap dynamoelectric machine has at least one substantially planar coil arrays formed by joining two or more sub-coils. Each sub-coil has a serpentine path about the stator perimeter that includes radial segments disposed to generate a Lorenz force with respect to the rotor magnets. The radial segments of the serpentine path joined by alternating inner and outer tangential segments. Each sub-coil starts with a proximal end at an outer tangential segments and a distal end about or within an inner perimeter of the inner tangential segments. Each sub-coil is joined at the distal end with another sub-coil to form the winding coil such that the proximal ends of the sub-coils constitute the two terminals of the planar coil array. This arrangement conveniently places both terminals of the planar coil array at the outer perimeter of the stator while also raising the winding inductance to a level more compatible with conventional motor power supplies. | 08-13-2009 |
20090200889 | Nested Serpentine Winding for an Axial Gap Electric Dynamo Machine - The stator of an axial gap dynamoelectric machine comprises two or more serpentine coil arrays that are formed form a continuous loop of insulated wire. The serpentine coils are deflected in at least some of the tangential components so the place radial segments disposed to generate a Lorenz force with respect to the rotor magnets in a common plane, reducing the gap there between. | 08-13-2009 |
20090200883 | Axial Gap Dynamo Electric Machine with Magnetic Bearing - An axial gap electric dynamo machine has a horizontally disposed rotor disk that is stabilized at its periphery by a plurality of permanent magnets connected to a ferromagnetic bearing plate that provides an opposing or repulsive force against the rotor magnets. In some preferred embodiments, the bearing plate magnets are configured in a dual band to further enhance the magnetic field that supports the periphery of the spinning rotor. | 08-13-2009 |
