The Grid Tie Inverter or Synchronous Inverter is a special type of power inverter that converts DC electricity into alternating current. A special feature of these types of inverters is that they can feed AC into the existing electrical grid. GTIs are often used to convert DC electricity produced...
Power generation for the small wind industry is experiencing a change. The demand for higher power turbines is increasing in many markets all around the world. Demand is moving from less than 1kw to 5kw and higher. These are generally for home purposes or businesses. Typically the speed of...
In this post we will discuss two features of windmill installation; Speed And Temperature. These play very important role in deciding what will the output be. Following two notes on these factors will give a good idea regarding these considerations. Speed Start-up Speed– The speed at which the blades begin...
Impressive Efficiency Results obtained during tests conducted by PM Generators Ltd. PM Generators Ltd. is best known for its world class permanent magnet alternators and best quality products. PM Generators Ltd. has further taken steps to maintain their competency in the industry by conducting efficiency tests the results of which...
Magnets Grade: The grade of a magnet refers to the maximum energy product of the material that composes the magnet. In simple terms it is to tell how strong the magnet is. The higher the grade the stronger the magnet is. Unit of energy product is Gauss. Sintered Nd-Fe-B will...
Bearings To get the correct efficiency one has to make sure that all the necessary measures are taken, like using the correct type of bearings. Commonly used sealed ball bearings should be correct in size and be able to withstand axial loads. Sealed Ball Bearings This type of bearing covers the balls...
The different types of materials required for a wind permanent magnet generator are mentioned below: Winding Wires In electric industries, winding wires play a very important role. Their role spreads from generators to transformers, control devices and pumps. Many materials can be used to make wires. The most popular material used...
A very important aspect of installing a wind mill is the shape of its blades. There are different materials from which the blades are made. A short note on blade design is presented to give a basic idea about this factor. Blade design The ratio between the speed of the blade...
In this post we will discuss two very important factors that define a windmill; its axis and its generator torque. The axis type of the windmill decides the whole process of capturing wind speed and the mechanism of converting it to electricity. Axis Vertical Axis Wind Turbines VAWTs have become popular in...
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...
