ArcelorMittal’s iCARe® family of electrical steels offers the lowest loss levels and excellent yield strength for e-mobility traction applications. Low losses are a particularly important characteristic of the iCARe® Save family. This property minimises the amount of battery energy that is wasted as unwanted heat dissipation. This enables OEMs to achieve longer drive ranges with existing battery technology.
iCare® 420 Save grades combine low losses with high yield strength. The guaranteed minimum yield strength of these grades is 420 megapascals (MPa). This allows OEMs to increase the overall compactness and performance of their electrical machines and to manufacture rotors and stators from the same material.
Motor designers can use the high strength of iCARe® 420 Save to improve the electromagnetic design of the rotor or to increase its rotating speed – both of which increase power density. The steels also exhibit very good punchability.
To help OEMs get the most out of our iCARe® electrical steels, ArcelorMittal offers state-of-the-art tools, technical support, and co-engineering solutions. As well as giving manufacturers access to some of the leading experts in the field of automotive electrification, it also helps them to extract the highest level of performance from our iCARe® electrical steels.
ArcelorMittal’s simulation tools and software can accurately calculate the efficiency of an electrical machine design. Modelling a new design with these tools allows customers to precisely estimate the level of performance and efficiency at each operational point. The tools can also identify and help to mitigate the effect of motor production steps on efficiency. The result is an optimised electrical machine that performs as designed.
The iCARe® range offers OEMs a choice of electrical steels which allow them to meet their requirements for low losses, high strength, and/or high polarisation. iCare® 420 Save is the flagship of the iCare® family. These enhanced Save grades combine low losses with higher yield strength (guaranteed minimum yield strength of 420 MPa) compared to the standard Save grades. The enhanced strength allows rotor design improvements which increase the overall performance and compactness of the electrical machine.
Led by the global account manager (GAM) and the global technical coordinator (GTC), ArcelorMittal’s customer teams also include customer technical support (CTS) engineers. The CTS handle all technical operational questions from the OEM and report back to the GAM/GTC.
Many OEMs also have an ArcelorMittal resident engineer (RE) to support product development and innovation. The RE can provide the latest information and technical data on ArcelorMittal’s offer directly to the customer’s R&D teams.
