give an brief idea to make an working model of windmill?

I am assuming that you want to make small-scale models for class-work?

The simplest thing is to add propellor blades to a small DC electric motor.  Connect the motor to a load instead of a battery (say, a small bulb or LED), and you can use ammeters and voltemeters to measure the power output.

Your class can then investigate the best kind of blades to use on a wind turbine.  Clamp the motor vertically, and you can also investigate vertical axis wind turbines (VAW turbines) such as the savonius.

I suggest doing a search on Instructables for "windmill."
