Abstract
Methods and apparatus are disclosed for assembling a motor rotor. The apparatus includes a rotor fixing module, a conductive bar driving module, a plurality of conductive bars and a pump module. The rotor fixing module supports and holds the rotor. The conductive bar driving module has a plurality of assembling slots. When the pumping module is attached to the conductive bar driving module and each of the conductive bars seals the assembling slots, the pumping module and the assembling slots cooperatively form a sealed chamber, and the pumping module vacuums the sealed chamber to generate a suction force on each of the conductive bars, and the suction force further drives the conductive bars into the assembling slots. The method is for assembling the rotor by utilizing the same procedure mentioned above.
