本発明は洗濯機など家庭用電化製品に用いる樹脂モール
ドモータに関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to resin molded motors used in household electrical appliances such as washing machines.
従来の技術
近年、樹脂モールドモータは騒音低減のため、あるいは
安全性向上のために、家庭用電化製品に数多く採用され
ている。2. Description of the Related Art In recent years, resin molded motors have been widely used in household electrical appliances to reduce noise or improve safety.
以下に従来の樹脂モールドモータについて説明する。A conventional resin molded motor will be explained below.
第６図に示すように、コネクタ８を通してステータコア
６に挿入されているコイル７に通電するとロータ９が回

る。As shown in FIG. 6, when the coil 7 inserted into the stator core 6 is energized through the connector 8, the rotor 9 rotates. 11 is a bearing, and 12 is a bearing housing. If the shaft 1o of the rotor 9 is immersed in water, such as in a dishwasher, technical standards require that the stator core 6 or rotor 9 be grounded.

入して接続するので工数がかかシかつ圧入したアース端
子がゆるむという問題点を有していた。Note that when used in a washing machine, the product is specified to withstand a certain level of pressure, so a pressure test is conducted upon completion. If the power is turned on, the microcomputer may be destroyed, so grounding is required. The ground wire 13 is soldered to the stator core 6, or as shown in FIG. 6, it is press-fitted into the stator core 14 instead of the ground wire 13. However, in the above-mentioned conventional configuration, the ground wire is soldered to the stator core, which reduces workability. The problem is that the soldering is poor and easily peels off, and the ground terminal is connected by being press-fitted into the stator core, which requires a lot of man-hours, and the press-fitted ground terminal becomes loose.
