Stator/rotor welding facility
Short project description:
The facility manufactures stator and rotor laminated sheet packages for the electric powertrain of the Renault Z.E. The electric motor of the Kangoo Rapid Z.E. has an output of 44kW/60 HP with 10,500 1/min. The maximum torque of 226 newton metres is available upon start-up.
The sheet packages are weighed using the integrated scales to ensure that the correct number of sheets is used. With the help of the filling guide, the sheets are positioned in the tool of the facility. Once the fully automated manufacturing process commences, the sheet package is compressed and measured behind the closed safety door. Any deviation from the required length is shown to the operator in the number of sheets (+/- sheets). Once the package has been measured successfully, the seams are welded using a generated G-code (interpolated line movements) and a rotational and welding axis. During the welding process, all welding streams of the individual burners, forces, speeds, etc. are recorded and saved in the SQL database. After the welding process, a gripper system places the welded package in the cooling section. At the control station, the packages are measured and the reference dimensions are added to the article data and saved in the database by a PC station.
