Latest Patents

**Method for Manufacturing a Stator.** This invention describes a process for covering a stator coil end with a resin layer. First, a liquid thermosetting resin impregnates the tip side of the coil end to form a first layer. A second thermosetting resin is then applied from the core side toward the tip, forming another layer over the first. Both layers are subsequently cured.

**Manufacturing Method for Electric Motor Stator.** This method involves injecting thermosetting resin into a forming die and dipping a coil end into the resin. The resin is heated to create a molded portion, which is released from the die when the resin’s shear force or its adhesive strength to the coil end exceeds a predetermined release force.
