Description
In the motor system, the motor shaft, as a core component for power transmission and support, its quality is directly related to the operating efficiency of the equipment. Our company has deeply engaged in the field of motor shaft production. With strict quality control and flexible customization capabilities, we provide a reliable power backbone for motors in various industries.
Precision Manufacturing, Adhering to Standards
The production follows a strict quality system, with full-process control from the incoming inspection of raw materials to the delivery of finished products. In the processing stage, high-precision CNC equipment is used, and the turning, milling, and grinding processes are precisely controlled. The key dimensional tolerance of the shaft can reach ±0.005mm, and the geometric tolerances such as cylindricity and circular runout strictly comply with national standards and high-end industry standards. Advanced processes are adopted for surface treatment, such as hard chrome plating to enhance wear resistance and Dacromet treatment to improve corrosion resistance. After salt spray testing, it can serve stably for a long time in harsh environments, ensuring that the quality of the motor shaft is always at a high level.
Reliable and Durable, Stable Transmission
The motor shaft undertakes the important tasks of power transmission and rotor support. We ensure high-quality performance through optimized design and processes. The reasonable shaft diameter design, transition fillet, and keyway layout can effectively disperse stress and avoid the risks of fracture and deformation during operation; strict dynamic balance detection ensures that the vibration value is ≤0.5mm/s when the rotation speed exceeds 10,000 revolutions, ensuring the stable high-speed operation of the motor, reducing noise and additional losses, and providing a solid guarantee for the stable and efficient operation of the motor system.
Power Hub, Collaborative Core
The motor shaft is a key hub for the power output of the motor, connecting the rotor and the external load, accurately transmitting torque, and realizing the efficient conversion of electrical energy to mechanical energy. In servo motors, the high-precision motor shaft ensures accurate positioning control and helps automated equipment achieve millimeter-level motion control; in industrial drive motors, the tough shaft body supports high-power operation and drives the stable operation of production line equipment; for new energy vehicle motors, the lightweight and high-strength shaft components improve the energy efficiency of the power system, promote the energy conservation and high-performance driving of vehicles, and are the power backbone for the motor to function.
Professional Accumulation, Worry-free Service
The company has rich experience in the R & D and production of motor shafts. The technical team has deeply engaged in the fields of mechanical design and material processing and has served many motor manufacturing enterprises.An exclusive project docking team is provided. From the communication of customization requirements (such as special structures and performance requirements) to the output of design schemes, feedback on production progress, and then to after-sales technical support, a one-on-one full-process service is provided. It can quickly respond to small-batch customization and large-scale orders, and become a trusted motor shaft partner for customers with professional, efficient, and considerate services.
From the adherence to the quality of precision manufacturing to the consideration of various applicable materials, from the stable and reliable quality guarantee to the key role of driving the motor, and then to the professional and considerate company services, our customized motor shafts create exclusive power cores for various motors. We look forward to working with you to empower the efficient development of the motor industry!
