Two Station New Energy Motor Rotor, EV Motor Rotor Automatic Balancing Machine
The Two-Station New Energy and EV Motor Rotor Automatic Balancing Machine is specifically engineered for high-precision dynamic balancing and automatic imbalance correction of electric vehicle and new-energy motor rotors. Designed for modern manufacturing environments, the system features an anti-magnetic measuring structure, a fully enclosed safety enclosure, and advanced balancing software to ensure accurate, efficient, and reliable operation.
The machine is capable of processing rotors weighing between 10 kg and 50 kg, with diameters ranging from φ130 mm to φ260 mm and lengths from 220 mm to 550 mm. A servo-driven balancing system provides adjustable operating speeds from 800 to 4000 rpm with high rotational accuracy. The robust cast-iron machine frame enhances structural stability, while the balancing support assembly is manufactured from anti-magnetic 304 stainless steel to ensure measurement reliability when handling magnetized components.
Automatic imbalance correction is performed through a dual-station drilling system, where servo-controlled power heads independently remove material from both ends of the rotor based on imbalance values and angular positions calculated by the balancing software. Pneumatic clamping mechanisms securely hold the rotor during the correction process, ensuring consistent and precise results. The system also incorporates a high-capacity vacuum extraction unit that efficiently removes drilling chips and prevents debris from dispersing into the work environment.
The equipment includes a dynamic balancing support assembly, dual drilling and correction units, pneumatic holding devices, a mobile drilling mechanism, and an industrial vacuum system. Operator safety is enhanced through a fully enclosed protective guard, visual status indicators, and automatic alarm notifications for abnormal operating conditions. The machine is suitable for balancing rotors manufactured from materials such as aluminum, copper, and stainless steel.
Designed to deliver exceptional balancing performance, the system can achieve a residual unbalance value below 0.2 g·mm/kg while reducing rotor imbalance by more than 90%, ensuring improved motor efficiency, reduced vibration, and enhanced product quality.
