The invention relates to a turbine engine motor having an unducted fan, the motor comprising a plurality of guide vanes (10) made of composite materials. Each of the guide vanes is intended to be fixed only to an inner fixed structure (20) of the turbine engine. The guide vane (10) comprises: an aerodynamic airfoil (12) which extends radially outwards along a radial axis (X-X); an outer radial end (14); an inner radial end (16); and an inner platform (18) which is configured to be fixed to the inner fixed structure (20), is attached to the inner radial end (16) by an inner attachment elbow (16a) and extends from the inner radial end (16) in a single first tangential direction secant to the radial axis (X-X) of the aerodynamic airfoil (12). The inner platform (18) comprises an opening (18a) for receiving a radial fixing system (30) for independently fixing each of the guide vanes to the inner fixed structure (20). A reinforcement element is arranged radially between the inner platform (18) of each of the guide vanes (10) and the inner fixed structure (20).
