3 Ton Electric Truck Motor Rotor Automatic Balancing Machine New Energy Motor Rotor Balancer
The 3-Ton Electric Truck Motor Rotor Automatic Balancing Machine is specifically engineered for dynamic balancing and automatic imbalance correction of new-energy vehicle motor rotors. Designed to meet the demands of heavy-duty electric truck applications, the system enables simultaneous balancing and calibration of two rotor assemblies, significantly improving productivity and operational efficiency. The rotor imbalance is corrected through a precision radial arc milling process that ensures accurate material removal and reliable balancing performance.
The measuring station incorporates a robust hard-bearing balancing system, combined with a universal joint drive and a high-power variable-frequency motor. This configuration provides high torque transmission, excellent adaptability to different rotor designs, and simplified setup during product changeovers. The correction unit utilizes a three-axis milling mechanism that can be adjusted to accommodate varying rotor dimensions and specifications, offering flexibility for diverse production requirements.
For enhanced rigidity and machining stability, the milling assembly is constructed using a heavy-duty cast iron dovetail structure. To safeguard both the workpiece and the equipment during the correction process, the machine is equipped with a dedicated workpiece stop mechanism. This safety system prevents unwanted rotor movement during milling operations and is hydraulically actuated with synchronized positioning on both sides, allowing quick and precise adjustment based on the rotor configuration.
Key Features and Production Advantages
