Abstract. Electromagnetic weft insertion technology has a broad application prospect in the weaving of wide-width textiles. Based on the principle of electromagnetic drive, this paper analyzes the factors that may affect the electromagnetic force. The electromagnetic weft insertion device without yoke is simulated by finite element simulation software. It is found that most of its magnetic field lines are diffused outwardly, the energy conversion efficiency is low and the electromagnetic force is unstable. Then a magnetic yoke is installed outside the drive coil. The results show that the magnetic field inside the drive coil increases significantly, the magnetic field line escaping to the outside decreases obviously, and the electromagnetic force received by the clip weft device increases and becomes more stable, which can effectively improve the efficiency of electromagnetic weft insertion.
