2 Exceed expectation2 EVI EVI Culture in Baosteel Baosteel could offer a variety of specialized services and technical support from material selection in design stage to traction motor iron core manufacturing, including:3 EVI4 Steel s EVI in Baosteel for Traction Motor of NEVS teel Product System for Traction Motor of NEV To support customers in electrical steel grade selection for motor design, in order to achieve excellent performance and cost control.

3 To support customers in optimization of material and structure of motor core to achieve performance improvement or cost reduction. To support customers in iron core manufacturing to achieve a good match between material and working facilities. To recommend customers with new products and new technology to improve the competency of their new Electrical Non-oriented Electrical 01 NON-ORIENTED ELECTRICAL STEELS FOR TRACTION MOTOR OF NEV02 permanent magnet synchronous machine (PMSM) is the mainstream of traction motor of NEV, requiring high efficiency, high torque, high reliability, compact volume, and etc.

4 Non-oriented electrical steel series in Baosteel could meet the requirements from all kinds of high performance motors with features of low iron loss at mid and high frequency, high induction density and high strength. Low loss series: low iron loss, high strength; High efficiency series: low iron loss, high induction; High efficiency-Higher strength series: excellent overall performance in loss, induction, and strength; Super induction series: high induction density to satisfy the needs for high torque and compact design of motors.
