It is very critical to understand the concept of wind before one thinks of generating electricity from it. There are many basics like wind blade designs, speed of wind, tower height, site location etc. which should be given due importance before going into windmill construction. This series of posts...
Many turbine manufacturers are moving towards direct drive turbines and leaving the traditional gearbox turbines behind. Direct drive turbines achieve more reliability, efficiency and reduce the overall cost of producing electricity. In a direct drive method, power is taken directly from the mechanical source without any efficiency reductions earlier...
Although the use of wind to generate electricity has been on a rise throughout the world, one country has exceeded all others in harnessing the power. Germany has the highest installed capacity in Europe. In the year 2011, the total installed capacity was 29,075 Megawatts. Some interesting questions that arise...
Wind energy is clean and green. It contributes towards a good percentage of total power generating resources any country has. This may reduce the consumption of other energy resources which use depleted resources and are not clean. Wind is variable and it does not provide its full power every single...
It is important for the customers as well as the manufacturers to know the voltage and rpm specifications of the product. But exactly how are they related? Simply said, voltage generated in an alternator is directly proportional to the speed of the generator or the prime mover; E = K...
Permanent magnet alternators can be operated at different speeds. Thus there are alternators working at low rpm and others at high rpm. This feature is suitable when these alternators have applications in various fields like wind turbines, hydro-kinetic energy and other renewable energy devices. For example, vertical axis permanent...
PM Generator Ltd manufactures high speed permanent magnet generators for domestic and international markets. These generators can be used for Diesel Generator Sets, Hybrid Electric Propulsion, Wind Energy and Hydroelectric purposes. The conventional DG sets use traditional alternators which are much larger, heavier, noisier and up to 35% less efficient....
How Permanent Magnet Generators Work? Permanent magnet generators are superior alternatives to traditional induction motors that can be coupled with turbines, diesel generators and used for hybrid vehicles. One of the biggest benefits of permanent magnet generators is that these do not require definite environmental conditions to work properly which...
Low RPM Generators Traditional generators need to revolve at 1800 revolutions per minute to generate power. This requires a great expenditure of energy to produce a feasible amount of power. With low RPM generators, there is the advantage of power production at low revolutions per minute. The low RPM generator...
PM Generators Ltd. has set up a factory in Northern India and is leading India's market place for permanent magnet generators from 1 kilowatt to 100 kilowatts. Generating power through permanent magnetic fields is the latest technology for powering windmills, hydro energy and hybrid vehicles. Deepak Singh, CEO of...
