  • L-T Series Magnets (.pdf)
    of magnets are suitable for advanced applications which has strict requirement of corrosion and heat resistance, such as elevators, radars, wind power generators. Please check the table below for more details and compare to the normal magnets.
  • When lightning strikes wind turbines
    for lightning strikes. Operators of wind-turbine installations (WTIs) of course want to minimize downtime and repairs. So well-designed surge protection is a necessity for this equipment. WTIs have a lot of technology crammed into a small space. A transformer station inside the tower adapts the generator
  • Green technology: Inside an advanced wind turbine
    the Quantum Drive) and high-efficiency, permanent- magnet generators. These pair up with a sophisticated control system that adjusts both rotor blades and generator operation to squeeze power even out of light breezes. The Liberty design also incorporates ideas aimed at simplifying the maintenance
  • April 21, 2009 - Wind-turbine drive takes the prize at Hannover Fair
    with a superimposing planetary gear stage. The system converts the variable speed of the wind-turbine rotor into a constant output speed for the generator. Control response takes as little as 20 msec, letting synchronous generators directly feed the power grid. Eliminating a frequency converter results
  • New developments on the turbine-power front
    Alternative energy is in the headlines thanks to recent efforts to generate electricity from the tides and wind. Inventor Doug Selsam's turbine produces power in 9-mph winds and puts out an average 1 kW at 25 mph (24-V nominal). Marine Current Turbines place two generating units on an arm that can
  • Battery Charging with Maximal Peak Power Tracking
    A maximal peak power tracking (MPPT) example for wind power plant is implemented in this example. The load is a battery that is subjected to a variable speed, realistic wind profile. The system simulated consist of the following components; a wind turbine, a planetary gear system, a generator
  • Structural Design Reduces Solar-Electric Power-Plant Costs and Improves Solar-Generating Efficiency
    thermal holds over other renewable resources is that, except for the troughs, the power plant is a standard design widely used by electric utilities. And generating capacity can be built close to where the power is needed. This is in contrast to wind-power-generation facilities. Because they must be near
  • Novel windmill captures more energy
    A novel 7-ft.-diameter wind turbine has set a record by producing 5.3 kW in a 32.5-mph wind. Doug Selsam holds a windmill design with 21 blades each 20-in. diameter, and a 0.75-hp generator. The design has only one moving part. Shafts on all designs are positioned at a slight angle from horizontal
