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.
To address the diverse corrosion challenges encountered across photovoltaic farms, wind power installations, and electric vehicle under-hood environments, Guanshuo offers a comprehensive portfolio of surface protection solutions for the New Energy Equipment Motor Shaft. Each option is validated through ≥500 hours of salt spray testing per ASTM B117 standards, ensuring long-term service life in aggressive operating conditions.
● Nickel‑phosphorus electroless plating -- provides uniform coverage on complex geometries with excellent anti-corrosion properties and moderate wear resistance
● Electrophoretic (E-coat) painting -- offers superior chemical resistance against coolants, brake fluids, and atmospheric pollutants
● Vacuum ion nitriding -- enhances surface hardness, fatigue strength, and galling resistance without dimensional distortion
● Stainless steel substrate (304/316L) -- delivers inherent corrosion resistance for the most demanding marine or chemically aggressive environments
Beyond standard offerings, alternative treatments including zinc-nickel alloy plating, DLC (diamond-like carbon) coatings, and thermal spray coatings can be explored based on specific application requirements.
Through a meticulously controlled sequence of quenching, tempering, and case hardening, Guanshuo achieves a metallurgical structure that balances high surface hardness with retained core toughness for the New Energy Equipment Motor Shaft. This combination is critical for shafts subjected to torsional fatigue, impact loads, and fretting wear commonly experienced in new energy motor applications.
● Surface hardness: HRC 58--62 (achieved through induction hardening or carburizing processes)
● Core impact toughness: ≥ 110 J/cm² (Charpy V-notch test)
● Torsional stiffness: ≥ 250 N·m/° (dependent on shaft diameter and length)
● Hardened case depth: 1.5 -- 3.5 mm (controllable based on design requirements)
● Fatigue life: baseline ≥ 15,000 hours under standardised cyclic loading
For applications demanding extended service intervals, additional enhancements can be incorporated, including rolling strengthening of fillet radii to mitigate stress concentration, and induction tempering to refine residual stress profiles. Our engineering team can perform custom FEA-based fatigue life predictions tailored to specific torque and speed profiles.
The New Energy Equipment Motor Shaft is manufactured to tight dimensional tolerances essential for high-speed rotating assemblies, where vibration, noise, and bearing life are directly influenced by geometric accuracy. Our CNC grinding and hard turning capabilities consistently achieve the following precision levels:
| Parameter | Specification | Measuring Instrument |
|---|---|---|
| Shaft diameter range | φ12 – φ80 mm | Micrometer / Laser gauge |
| Surface roughness | Ra 0.2 – Ra 0.4 μm | Surface roughness tester |
| End face run-out | ≤ 0.005 mm | Dial gauge / CMM |
| Hardened case depth | 1.5 – 3.5 mm | Microhardness tester |
Key connection interfaces can be customised with spline profiles, tapered surfaces, flat or keyway configurations, and hollow cross-sections to accommodate weight reduction or internal cooling requirements. All dimensions follow general new energy equipment standards and can be adapted to customer-specific drawings (ISO, DIN, JIS, or ANSI compatible).
Inspection equipment includes hardness testers, 2D projectors, surface roughness gauges, gear testing centres, and cylindricity measuring instruments.
