rotor core assembly
Complete rotor core assemblies consisting of laminated rotor cores, aluminum die-cast bars and end rings, and shaft assembly. Manufactured with high precision and excellent magnetic and mechanical performance, with full customization available for dimensions and structure, suitable for high-efficiency and high power density motor applications.
Rotor core assembly is the core component of the motor rotor system, consisting of rotor laminations, shaft, aluminum die-cast bars, and end rings. It is widely used in industrial motors, high-voltage motors, wind power generators, and new energy drive systems. The manufacturing precision, magnetic performance, and structural stability of the rotor core assembly directly affect motor efficiency, torque output, vibration, noise, and reliability.
We provide a complete rotor core assembly solution, including lamination stamping, stacking, aluminum die casting, shaft assembly, and inspection. Supported by precision tooling, high-speed stamping equipment, and large aluminum die casting machines, we ensure excellent dimensional accuracy, stable magnetic performance, and high mechanical strength for demanding motor applications.
