The globally first-to-market product ESW8517 has set a new industry record with its global lowest iron loss of 7.9W/kg (400Hz), and its magnetic performance indicators at a thickness of 0.1mm have reached the world's leading level. This product not only represents a major breakthrough in performance but also makes an innovative progress in balancing strength and magnetic performance. With a yield strength of 490MPa, it increases the safety factor of the motor by 11%, and improves the motor efficiency by 0.72% under CLTC conditions. The launch of ESW8517 precisely matches the future design trend of high-speed motors, injecting strong impetus into the upgrade of high-efficiency motors and the new energy vehicle industry, providing a new technical solution for achieving the "dual carbon" goals, and leading the industry towards a new era of high efficiency and low carbon
The disruptive design opens up a "second curve" for motor performance improvement, not only fundamentally solving the problem of severe deterioration

of iron loss during the process of iron core casing, but also contributing to the improvement of iron loss, significantly enhancing motor performance. This technology can also be combined with self-bonding and annealing technologies, pushing the comprehensive performance of motors to a new dimension and opening up a new technical route for breaking through the performance limits of motors. The pioneering thin-film high-viscosity self-bonding coating technology increases the bonding strength by 50% under the same film thickness and reduces the film thickness by 30% under the same bonding strength, further enhancing the applicability of rapid self-bonding in the field of new energy vehicle motors, providing new material technology support for ultra-quiet, high-efficiency, and extremely stable new energy vehicle.

 

The picture above provides an introduction to the parameters of other steel grades.The globally first-to-market product 20RSW175 is a high magnetic permeability non-oriented soft magnetic material specifically designed for humanoid robots. With a magnetic induction intensity of 1.75T, it increases the torque by 1.6% compared to conventional products and reduces iron loss by 27%, effectively meeting the development needs of high torque density and high power density for frameless torque motors used in humanoid robots. It fills the gap of high magnetic permeability non-oriented soft magnetic materials in China and ignites a new engine for the development of the Chinese humanoid robot industry.
