Applying Patented Rotor Technology

to Customer Products

Patented Rotor Die-Casting Technology

Our self-developed patented rotor die-casting technology upgrades the whole rotor manufacturing process.Every internal structural detail of the rotor is precisely controlled.

Integrated forming of rotor lamination, end ring and end cap avoids loose assembly and energy loss.Our finished rotor cores feature lower iron loss, higher conductivity and stronger structural rigidity.

We provide reliable, energy-saving rotor component solutions for all kinds of motors and pumps.
