motor squirrel cage rotor 

At present, the modern stamping equipment used for stamping stator and rotor core parts of motors mainly includes: Germany: SCHULER, Japan: AIDA high-speed punch, DOBBY high-speed punch, ISIS high-speed punch, the United States has: MINSTER high-speed punch, Taiwan has : Yingyu high-speed punch, etc. ROTOR CORE Just like the stacking of the stator, the rotor lamination cannot deviate when it is pressed by the hydraulic press, otherwise the actual size of the rotor slot will change less than the design size, which will make the magnet or conductor bars inserting more difficult. The rotor cores we currently produce are mainly cast aluminum rotors and copper rotors with shafts. The lamination stacking process of the cast aluminum rotor needs to use a high-precision mandrel during the lamination process, if the rotor is skewed design, the mandrel must have a corresponding key. Rotor core stacking process is similar to the stator core…
