A small multi-blade wind turbine is an alternative technology in order to electricity generating for use in a household because of the construction is cheap. From the study, the performance calculations by simulation program show that a number of blade at 12 blades is the optimum value for applying to this wind turbine that give maximum power coefficient of 0.29 at a tip speed ratio of 1.2. The results from the test run of wind rotor connected with generator in the wind tunnel at a wind velocity of 2 m/s, 3 m/s and 4 m/s, the system give the electric power of 2.5 W, 4.25 W and 4.49 W respectively.
