ArcelorMittal出专用于电动汽车电机的硅钢片了，大家来讨论下~
本帖最后由 Edwin_Sun 于 2012-7-1 20:38 编辑ArcelorMittal宣布开发出了专用于电动汽车电机的硅钢片材料并推向市场，让我们大胆的来推测一下这种硅钢片材料的基本属性，以及该种材料对未来电动汽车用电机设计的影响~
不知道国内有没有类似的产品出来，性能如何？
有意义的帖子加分呀~
ps，那种说看不懂英文等来灌水的就别来灌水了~
具体的报道如下英文版所示。
As EV production ramps up around the globe, companies are developing ever more components and materials optimized for use in electric and hybrid vehicles. At this week’s Coil Winding, Insulation and Electrical Manufacturing trade fair in Berlin (doesn’t that sound like a glamorous event?), steel giant ArcelorMittal unveiled a range of electrical steel products designed specifically to meet the requirements of EV manufacturers.
Electrical steels are specialty steels tailored to produce certain magnetic properties - strips of electrical steel are stacked (laminations) to form electric motor stators and rotors. ArcelorMittal’s iCARe portfolio was created to help carmakers deliver lower emissions and improved fuel consumption for hybrid vehicles, or longer range for pure EVs. The iCARe steels promise to deliver increased power density from electric motors, helping to reduce the size and weight of a vehicle via enhanced energy efficiency.
The iCARe portfolio includes three grades of electrical steel:
The iCARe Save range offers low electrical loss, maximizing use of current batteries and allowing electric vehicles to drive further on a charge. Save grades reduce the iron losses from the stators of synchronous machines, helping to improve efficiency, which leads to an increase in power density. Power density can be tuned to create a lighter, smaller machine, or a more powerful machine for a given weight.
The iCARe Torque products ensure the highest levels of mechanical power output from EV motors. Torque grades are suitable for machines which need high torque at low speeds.
The iCARe Speed steels provide a compromise between mechanical properties and losses. They deliver very high strength, making them suited for the manufacture of high-speed rotors that allow a further weight reduction of the motor.
As part of the iCARe project, ArcelorMittal plans to invest $112 million to build a new continuous annealing line at its production facility at St-Chély d’Apcher, France. The line will be capable of producing up to 120,000 tons of iCARe steel per year. 猜测一下
三种大概是：
1、低铁损，可能是减薄了厚度
2、高磁感，在炼钢环节有所改进
3、高强度 回复 2# 张老五
还有，降低产品成本 回复 3# pat
虽然降成本是用户共同的心声，但从报道里没看出来有降成本的信息 有降成本啊
低损耗，可以提高AJ
高磁感，提高功率密度
…… 有降成本啊
低损耗，可以提高AJ
高磁感，提高功率密度
…… 反问：1. iCARe 同一产品能否兼顾高磁感和低铁损？
2. 有木有改善的相对幅度数据！
若不能回答这2个问题，就有广告的嫌疑。 回复 7# caohongfei
基本信息到他们网站上找吧。
同一产品很难做到同时兼顾高磁感和低铁损，这本身是矛盾的。 汽车 电 机用 的
