摘要：
A squirrel-cage rotor of an asynchronous machine has a rotor bar (4) in a rotor stack (1), wherein the bar (4) can be tipped at a tipping point (11, 12, 13) when the bar (4) has not yet been cast. The rotor bar (4) can in this case have a contour on a radial outer face, wherein the bar (4) can also have a channel (27), the opening (29) in said channel being wider than the shoulders (32, 33) of the limbs (30, 31) which form the channel (27).
