EV Motor Rotor Automatic Balancing Machine Magnetic Motor Rotor Balancing Machine
The Magnetic and New Energy Motor Rotor Automatic Balancing Machine is a fully integrated solution designed for dual-plane dynamic balancing and end-face drilling correction of a wide range of rotating components. It is suitable for both magnetic and non-magnetic applications, including new-energy vehicle motor rotors, EV motor rotors, electromechanical spindle rotors, center-drive motor rotors, hub motors, and asynchronous induction motors. The system combines precision measurement and automatic correction within a single platform to improve balancing accuracy and production efficiency.
The machine accommodates rotors with shaft diameters ranging from φ20 mm to φ80 mm and rotor diameters between φ130 mm and φ220 mm. Its specially engineered support structure is designed to provide stable mechanical force transmission while maintaining excellent rigidity and minimal vibration interference during operation. This robust construction ensures consistent balancing performance and long-term reliability in demanding industrial environments.
Equipped with high-sensitivity sensors, the system delivers accurate and repeatable measurement results with excellent linearity and durability. Dynamic balancing calculations, rotor phase control, and correction processes are managed through a PLC-based control system, ensuring precise and reliable operation. An intuitive touchscreen interface serves as the operator control panel, allowing easy parameter configuration, process monitoring, and machine operation. The user-friendly design simplifies setup procedures while enhancing productivity and balancing consistency across different rotor types.
