The surface of the China New energy equipment motor shaft by Guanshuo supplier is made of nickel-phosphorus plating, electrophoretic painting, vacuum ion nitriding or stainless steel base material (304/316L), which is resistant to outdoor salt spray, vehicle coolant, and damp condensation corrosion at photovoltaic or wind power sites. The salt spray test time is ≥500 hours, meeting the anti-corrosion requirements for multi-environment procurement of new energy equipment. After quenching and tempering and surface hardening treatment, the surface hardness is HRC58-62, the core toughness is ≥110J/cm², and the torsional stiffness is ≥250N·m/°. It can withstand the alternating loads of high-frequency start and stop and sudden torque changes of new energy motors, meeting the mechanical requirements of high-reliability procurement. A long-life and fatigue-resistant design can be adopted to enhance durability.

The basic dimensions of the New energy equipment motor shaft follow the general standards for new energy equipment (such as the national standard for on-board motor shafts and the industry standard for wind turbine main shafts). The key connection sections can be customized with splines, conical surfaces, and hollow shaft structures. The delivery cycle is short, meeting the procurement requirements for large-scale mass production in the new energy industry. High torque and impact resistance, high-frequency start and stop for greater durability: Resistant to sudden torque changes and alternating loads.
