铸铜的主要难点在工艺，因为铜的熔点比铝高很多，我比较关心铸铜工艺对硅钢片的性能是否有影响

同问铸铜跟铜条比有什么优越性
不跟铸铝比，只跟铜条比

批量生产的话效率会高一些吧，如果插入铜条再焊端环很浪费时间（尤其对于槽数较多的电机）
注意每根铜条和端环都有经过车铣

如果只是为了一点生产效率，那实在是不值得。毕竟铸铜工艺还是相当的不成熟，能耗、流动性、温度对硅钢片和绝缘层的影响，都还没有定论。
再说了，铸铜的生产效率就一定高吗？铜条的就一定低吗？铜条和瑞环虽然是加工件，但这个可以单独做，批量做。插完铜条再焊瑞环，现在多半用中频焊，一个环一下子就都焊好了，也不费什么事，反倒是之前的预热比较费时间。

可以参考：
As the electric vehicle (EV) party gets—dare we say?—amped up, there’s something that throws a wet blanket on things to a certain extent: The availability of rare earth materials that are used in the powertrain, as in the magnets. As is the case with other powertrain-related materials (think: oil in another context), not all of the rare earth materials are readily available (they are, after all, rare), and according to the people at the International Copper Association, “Currently, China holds 95 percent of global production capacity for the rare earth minerals and dominates rare earth magnet production. China’s Ministry of Industry and Information Technology is enforcing tight limits on production and export of these materials.”
So, what’s an electric motor producer to do?
Well, the source of that quote is a clue, as the organization claims that copper can be “an efficient replacement” for rare earth materials in the manufacture of induction motors for EVs.
In addition to which, the ICA claims that it is more economical than using rare earth materials, which is helpful, given the prices of batteries.
And the use of copper for EV motors is not a theoretical exercise.
Telsa Motors is using a copper rotor for its motor, a motor that generates 300 hp and weighs 100 lb.
According to J.P. Strauber, vice president at Tesla, “In a world where we are building millions of electric vehicles, I think the copper motor rotor will be the technology of choice to make that happen.”
Of course, that “millions of electric vehicles” remains to be seen

下次把特斯拉的电机专利放上来～

只是说是“铜转子”，看不出是“铸铜转子”，从图上看，还是像铜条的。
至于这个功率么，看不出是主要靠提高转速，还是有什么别的技术在里面
Show 一下我们做的永磁油冷的。相互学习。

看到他们小电机--60KW峰值功率图纸，转子是焊接铜条。
大电机也应该是焊接的吧！
台湾的一家企业在做Tesla驱动电机，应该能查得到吧。
楼上说的台湾企业 是不是AC Propulsion

不是AC Propulsion，是台湾富田电机
