Three-station balancer for EV electric motors

CEMB’s automatic balancing machine for electric motors is designed to precisely balance electric rotors up to 50 kg, including magnetized ones. It ensures extremely short cycle times and boosts productivity thanks to three separate stations.

Features

  • Automatic balancer for high-performance electric motors, with two independent measuring stations and one correction station to ensure extremely short cycle times.
  • Ideal for e-vehicle applications: supports balancing electric rotors up to 50 kg, magnetized or non-magnetized.
  • Four-arm loading system designed for maximum positioning accuracy and rotor protection.
  • Unbalance correction on all materials by axial drilling or complex milling (arcs, slots), with 6 electric axes for simultaneous operations on both flanges.
  • Intelligent touch device with automatic unevenness compensation, poka-yoke system for correct parameter setting.
  • Machine prepared for connection with supervisory and production management systems. It integrates data exchange logic with MES platforms, enabling real-time tracking and monitoring.
  • Augmented reality remote assistance and integration with automated assembly lines for globally optimized production flow.

      Magnetized rotor kit

      Dedicated solutions for handling and balancing magnetized rotors.

      Electronic index

      Electronic system that identifies specific rotor reference points to allow correction in specific areas or take into account systematic workpiece imbalance.

      Data matrix reader

      Manual or automatic data matrix code reading system for part traceability.

      Automatic change over

      Automatic handling for fast and accurate production changeover as an alternative to a manual operator setup.

      Minimal Lubrication (MQL)

      Minimum Quantity Lubrication (Minimum Quantity Lubrication) air-oil system that uses a small amount of oil dispersed in a jet of compressed air to lubricate and cool the tool during machining.

      Tool cooling

      Cooling system to prevent overheating during correction and preserve the tool.

      Tool wear control

      Automatic tool wear detection system in the case of drilling and milling, which ensures maximum efficiency and safety, avoiding machining with unsuitable tools.

      Production control with reference piece

      Cyclic production control system using part reference, which verifies the quality and repeatability of the production process.

      Laser marking

      Non-contact device that uses a laser beam to etch the surface of the rotor.

      Countersink

      Specific tool for removing possible post-correction burrs.
