www.infineon.com – Energy means life: It heats houses, powers cars and lights megacities. The global appetite for energy is voracious, while resources are dwindling. One third of the energy consumed worldwide is electricity and the trend is rising. The name of the key energy source of the future is energy efficiency. Optimal electricity use is achieved by harnessing smart semiconductor technology: Innovative chip solutions fine-tune cars, industrial plants, consumer and household electronics to use less energy. And smart meters permit evaluation of every kilowatt hour with to-the-minute accuracy, helping to save electricity. The future of Wind Energy can be identified in offshore areas worldwide. Looking just at the North- and Baltic Sea, around 30 offshore wind farms are planned to come up in the next few years. Tomorrow’s electricity grids will be smart The electricity grids of the future will feed themselves locally from wind, sun and water. However peaks and troughs are inevitable. Smart grids will control the power supply and demand thus ensuring a reliable flow of current. Employing Infineon’s innovative semiconductor solutions means that electricity comes from the socket with low losses. Our power electronics transmit energy from the power station to the consumer efficiently, over thousands of kilometers.

No oil change or replacement of the bearings, gears. Since, MAGLEV does NOT require such. ** Current bearing technology has forced wind turbine designers into horizontal spindle three bladed wind turbines. In this design the huge blades are connected to a spindle in the center. The bearings that support the spindle and control the pitch of the blades (which can be hundreds of feet long) see huge pitch-moment loading, some of which is manifest as torque energy that is focused through the center spindle. The target speed for the spindle is 18 or 20 rpm and the bearings holding the spindle are mounted in a huge casting which also contains a large gearbox stepping the speed up to 1800 to 2000 RPMs which allows for the proper surface speed relationship between the coils and magnets. It is necessary to invert or condition the current, which is expensive. This gearbox is full of many large bearings, gears and castings; for a 2 MW turbine the gearbox can easily weigh 30 tons. This gearbox needs to be mounted on the top of a pole more than 150 feet in the air and be able to support the turbine blades under full-force wind conditions. ***MAGLEV Power Generation, the pitch moment ratio is closer to 1-to-1 then the 100-to-1 as with a horizontal spindle design.
