Drive motor for sewing machine, which allows the stop of the machine needle, either at the top dead center, or at the bottom dead center, characterized in that the motor housing supports a hollow shaft on which it is located. Placed the stator, while the rotor is mounted in loco on supports integral with the hollow shaft; the latter contains a shaft that can run transversely and on which a brake and a main clutch are mounted on the one hand and, on the other hand, the hub of the transmission pulley of the movement to the sewing machine; a second clutch, commanded by a speed reducing device by means of a freewheel, whose mission is to allow the clutch disk a greater speed with respect to the integral sleeve of the reduction gear, cooperates with the main clutch to obtain two speeds of rotation of the sewing machine, one of whose ends of the shaft carries a select inverter that controls two electrical circuits, which feed an organ that commands the displacement of the sliding shaft in order to place the needle of the sewing machine in position, either at the top dead center, either at the bottom dead center.
