We present a model for the generation of magnetic fields in fully convective pre-main sequence stars. The dynamo process in this type of star is of -type and hence quite different from the solar dynamo. Based on a mean field model of the turbulent electromotive force, the nonlinear induction equation is solved in three dimensions to allow for non-axisymmetric solutions. The resulting magnetic field is purely non-axisymmetric and steady.
