The invention discloses an integrated cast
copper rotor. The integrated cast
copper rotor is mainly characterized in that a rotor iron core is formed by laminating a certain number of
silicon steel sheets with same size and shape, installation holes are formed in the center of the
silicon steel sheets, a certain number of conduction bar holes are uniformly formed at the periphery of each
silicon steel sheet, the conduction bar holes of all silicon steel sheet are laminated and connected to form conduction bar grooves in the rotor iron core, conduction bars are die-casted in the conduction bar grooves, press plates are arranged at the two ends of the rotor iron core and are die-casted and connected with the conduction bars, the silicon steel sheets are circularly-shaped, the conduction bar hole on each silicon steel sheets is a combined hole of a
waist-shaped hole and a round hole, the
waist-shaped hole is large in one head and small in the other head and is arranged along a
diameter direction of the silicon steel sheet, the
large head of the
waist-shaped hole is arranged at the outer side of an annular circumference of the silicon steel sheet, the
small head of the waist-shaped hole is arranged at the inner side of the annular circumference of the silicon steel sheet, the round hole is arranged outside the
large head of the waist-shaped hole, the
large head of the waist-shaped hole and the round hole are communicated via a narrow connection gap, the width of the gap is smaller than the width of the waist-shaped hole and the
diameter of the round hole, and a certain number of rectangular grooves are uniformly arranged on the outer end surface of each press plate along the
diameter direction of the press plate.
