Abstract—An energy crisis is the major problem in all over world. Most of energy requirement is fulfilled by thermal power plants based on coal and diesel, which leads to environment pollution. To avoid these polluting power sources we have to adopt alternate energy resources like solar power, wind power, etc. But out of all these wind energy is preferred as domestic safe-economical energy resource. Wind turbine can be utilized on underutilized land or on lands currently in commodity crop production and which can be ‘harvest’ on the surface and ‘harvest’ above the surface. Then it will primarily be used for electricity generation for immediate end-use or as a ‘driver’ for hydrogen production. The traditional wind turbines are replaced by adopting the venturimeter shaped ducted turbine we can increase the wind velocity about three times (09-15 m/s) which is suitable for running the generator to its rated speed (200-600 RPM) without using the gear-box, so that the maximum power is generated from low velocity wind without loosing power in transmission system. The radial-flux PM machine with surface mounted magnets seems to be a good choice for the design of a large-scale directly driven wind-turbine generator. Small sized compact units of this kind of turbine may be constructed of throat diameter ranging between 0.5 m-01 m which can produce power from 100 W to 500 W with approximate cost ranging between Rs. 25,000 to Rs. 50,000, Which can be afford by a rural people easily
