Abstract
A rotor of an electric motor including a rotor core, two conductive end plates, a plurality of conductors and a casting metal is provided. The rotor core has a central hole and a plurality of slots surrounding the central hole at a predetermined interval. The two conductive end plates, disposed at two ends of the rotor core, have a plurality of fixing structures, respectively. A plurality of cavities is disposed between two neighboring fixing structures and the shape and the positions of the cavities correspond to that of the slots. The conductors are shaped as long bars and penetrate the slots. Two ends of the conductors are fixed by the fixing structures. The casting metal is injected into the cavities and the slots, and further covers the peripheral of the conductors and the fixing structures, two ends of the rotor core and outside of the two conductive end plates.
