| Abstract |
The aim of this communication is to study a doubly slotted reluctance generator for
direct driven wind energy conversion. This structure is known for its operating at high torque
and low speed but its power factor is generally very poor. To get over this disadvantage, we
propose a structure which is excited by permanent magnets inserted in the rotor.
In a first part, we present the proposed machine and the calculations which allow to determine
the geometric parameters and the windings polarities for a given speed. The determination of
magnetic parameters is achieved using an analytical approach and Finite Element Method
(FEM).
In a second part, we calculate the inductances by both analytical and FEM approaches and
achieve a three phase modelling.
To complete our study, the simulation of the machine, loaded by resistances, is performed by
FEM .and using the three phase modelling. Results are given and discussed. |
