Copper rotor

A copper rotor comprises a silicon steel plate module, two copper rings and a plurality of copper stripes. The silicon steel plate module is clamped between the two copper rings, and each copper ring has a through hole formed at the center of a surface of each copper ring, and each copper ring has a plurality of penetrating holes formed with an interval apart from each other on a periphery surface of each copper ring, and silicon steel plate module is formed by stacking a plurality of silicon steel plates, and each silicon steel plate has a perforation formed at the center of a surface of the silicon steel plate and a plurality of containing holes formed with an interval apart from each other along the peripheral surface of the silicon steel plate, such that the containing hole of adjacent silicon steel plates and penetrating hole of the copper ring are interconnected. Each copper stripe is passed through the plurality of containing holes interconnected to the silicon steel plates, and both ends of the copper
