Manufacturing method of water protection structure of motor, involves curing outer wrapping material, and softening inner wrapping material so that outer wrapping material flows out through opening and closes opening
The inner wrapping material is provided to enclose (S2) the motor stator, and the outer wrapping material is enclosed (S3) by the inner wrapping material. The outer wrapping material is formed with an opening. The outer wrapping material is hardened (S4) by heat, and the inner wrapping material is softened at the same time, so that the outer wrapping material flows out through the opening of the outer wrapping material and closes (S5) the opening of the outer wrapping material.
