Abstract： Due to second harmonic electromagnetic force, the end winding coil was subject to vibration damage，which is an important part of F4 three-phase synchronous motor stator for precision bar steel in Bao steel. A modal testing has been carried out on the winding coil, and of which some first modes acquired. The test shows us some appropriate positions for fixtures and where the maintenance should pay attention or on which the short circuit and damage happen more
