| In a setting step, a plurality of steel plates configuring a rotor core stacked in an axial direction of a rotor is set in a predetermined position in a mold that is capable of being opened and closed by relative movement in the axial direction. In a casting step, molten metal is fed into a molten metal introduction passage to form a conductive member of the rotor. The molten metal introduction passage has a ring-shaped gate that is opened so as to oppose one axial end surface of the steel plates set in the mold. In a cutoff step, the molten metal is cut off in the molten metal introduction passage so as to be separated into a gate side and a molten metal introduction opening side. In a mold-releasing step, the mold is opened such that a casting configuring the rotor is removed from the mold. | ||||||

| A rotor core for an electric motor includes a stack of laminations having peripherally spaced openings receiving copper bars with opposite end portions projecting from the stack. The core is mounted on an arbor and is inserted into a mold on a vertical die cast press having a shot chamber. The mold has upper and lower mold members defining annular cavities receiving end portions of the bars. Molten copper or aluminum is poured into the shot chamber and forced upwardly by a shot piston through passages in the lower mold member and into the cavity around the lower end portions of the bars. The pressurized molten metal solidifies and shrinks around the bar end portions to form an endring for the rotor. The core, endring and arbor are inverted and confined in the mold, and the casting steps are repeated to form the opposite endring. | ||||||

| Ceramic adhesive is applied inside the slots of an electric machine squirrel cage rotor prior to casting or insertion of rotor conductors. This heat-resistant insulation provides superior electrical insulation that is also mechanically rugged, thus enabling casting of squirrel cage rotors by die or cost-effective consumable pattern casting. The consumable pattern cast copper rotors are electrically well insulated, thus minimizing rotor losses. The ceramic insulation in cast rotors enables longer conductors to be cast by thermally insulating the molten metal from the cooler laminations. The ceramic insulation in fabricated rotors withstands the high temperatures of end ring attachment. This method is applicable to both conventional induction machine rotors and brushless doubly-fed induction machine rotors and provides the degree of electrical isolation of the bars from the laminations needed to avoid excessive parasitic torques in doubly-fed machines, while ensuring adequate thermal conductivity to dissipate conductive bar heat to the laminations. | ||||||
