Aluminum rotor casting for large oil equipment

Rotor Core

The traditional method of making iron cores is to punch out stator and rotor punching pieces (loose pieces) with ordinary ordinary molds, and then use rivet riveting, buckle or argon arc welding and other processes to make iron cores.

Most of the Motor Rotor fabrication doesn't use welding techniques. 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. 

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.
