<p>This rotor (8) extends along an axis of rotation X-X, and comprises a short-circuit cage (14) having at least one shorting bar (20) and at least one first electrical and mechanical short-circuit ring (16), each bar having a first end portion (24), said first end portion (24) being connected to the first short-circuit ring (16) mechanically and electrically by a connecting means (30). The connecting means (30) is a form-fit connection holding the end portion (24, 26) relative to the associated short-circuit ring (16, 18) in a holding direction (S) which extends radially relative to the axis of rotation. When the rotor is not turning about the axis of rotation of same, the connecting means (30) prestresses the end portion (24, 26) in a prestress direction (P) having a radial component relative to the axis of rotation, which is particularly directed radially relative to the axis of rotation. Application to the rotors of asynchronous motors.</p> |
