Abstract: A power collection device includes a carrier and a connection portion integrated with or attached to the carrier. The connection portion has a via for a wire to pass therethrough, a first side being in contact and connection with the carrier, a second side opposite to the first side, and a third side connected with the first and second sides. The via is in a shape of a circle, rectangle, square, rhombus, triangle with one side being close to the second side, or triangle with one angle being close to the second side. The via has a maximum length in a direction parallel to the first side being ¼ to ¾ times a length of the first side, and a maximum length in a direction perpendicular to the first side being ¼ to ¾ times a length from the first side to the second side.

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.
