PROBLEM TO BE SOLVED: To provide a technology capable of forming a stator coil with a material different from that of a power supply line without considering a connection structure for dissimilar metals.SOLUTION: A stator of a motor 100 includes stator coils 111-113 of first to third phases. One-side ends 111a-113a of the stator coils 111-113 are connected in common for forming a neutral point connection part 151, and other-side ends 111b-113b are connected to power supply lines 21-23 of first to third phases. The stator coils 111-113 are formed from materials including aluminum and the power supply lines 21-23 are formed from materials including copper. In the neutral point connection part 151, an electro-corrosion prevention part 161 is provided. The electro-corrosion prevention part 161 is formed from a material having an ionization tendency which is greater than that of the materials including aluminum forming the stator coils 111-113.SELECTED DRAWING: Figure 1 |
