| Abstract |
In an effort to introduce a low cost (PM less), low power electric wind or hydro generators, this paperreports on preliminary optimal design aspects and FEM analysis of a 3kW, 250 rpm, dual statorwinding asynchronous (DSWA) generator. At the first stage the single winding, three phaseasynchronous rotor is optimally designed for low speed and low frequency considering the influenceof the poles pairs on the main dimensions, weight, active material cost and efficiency. Than, the ratedpower and cost reduction of the inverter is analyzed considering dual stator winding asynchronousgenerators in two topologies: with the inverter placed on the excitation windings and with the inverterplaced on the main winding. The analytical model used for optimal design and the model of the doublestator winding is validated trough finite element method. Finally the proposed solutions are comparedwith the single winding induction generators. |
