Abstract
Wind power plant is one of the renewable energy where energy utilization is ± 3-5% from potential existing of wind power. Wind power plant requires a generator to convert mechanical energy into electrical energy, mostly the generators available in the market is a kind of high speed induction generator which requires high rotational speed and an electricity to generate a magnetic field. While in wind power plant needs low speed generator and without initial electricity. Hence, a radial flux generator is designed in this project to have low speed rotation using permanent magnet type Neodymium Iron Boron (NdFeB). Finite Element Method (FEM) Magnet software is used for designing the generator model. Several modifications are applied to get optimum result by changing generator diameter, number of coils, the copper wire diameter, number of poles, and used slots. The simulation results obtained generator speed 500 rpm, the average series voltage is 185.44 Volt. Generator requires 18 cm diameter, number of turn for each coil is 55, diameter of the copper wire used is 0.6 mm, and number of poles is 8 pairs and 12 unit slots.
