Aluminum centrifugal cage rotor for high voltage motors

Now with the rapid development of high-speed stamping technology, high-speed stamping multi-station progressive dies have been widely used in the fields of motors and electrical appliances to manufacture automatic laminated structural iron cores.

Rotor Core

After the rotor laminations are stacked, copper or aluminum circuits or permanent magnets will be embedded according to the design requirements. We are able to provide all types of Rotor Assembly for medium-to-high voltage motors and generators. Most Motor Rotor fabrication doesn't need welding techniques. 

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.
