In specific application, at the feeding station, the stator coil to be coated with powder is placed on the charging mold 1 1. When the sensor module senses that there is a stator coil on the charging mold 1 1, the lifting cylinder 7 drives the moving plate 8 to move down along the guide rail 9, driving the charging mold1/kloc-0.
