摘要： PURPOSE:To increase the lifetime of a stator by molding with resin a coil end, and winding a water shielding tape and a resin-immersed high strength fiber cloth tape, thereby increasing the water resistance of the stator. CONSTITUTION:The coil end 3 of a stator is molded with resin 4 in a compact manner, and a water shielding tape 5 is wound in a toroidal shape on the entire peripheral surface of the molded stator 1. Then, a resin-immersed high strength fiber clock tape 10 is wound in a toroidal shape on the outer periphery of the wound layer of the tape 5, the wound stator 1 is then inserted into a mandrel which is slightly larger than the outer diameter of a rotor, the resin is cured, and the mandrel is pulled out after the curing. Then, the temperature rise of the stator can be suppressed, the water resistance can be improved, and the lifetime of the stator can be increased.
摘要翻译：目的：为了通过树脂一个线圈端成型来增加定子的使用寿命，并缠绕一个防水带和一个树脂浸渍的高强度纤维布带，从而提高定子的耐水性。构成：定子的线圈端3以紧凑的方式模制树脂4，并且在模制定子1的整个外周表面上以环形形式缠绕防水胶带5.然后，树脂浸渍的高强度纤维时钟带10在带5的卷绕层的外周上以环形形状缠绕，然后将缠绕的定子1插入到稍微大于转子外径的心轴中，树脂固化，固化后拉出芯棒。因此，能够抑制定子的温度上升，能够提高耐水性，能够提高定子的寿命。
