Abstract: The invention relates to a stator (8) for an electric rotating machine (2), which stator has a laminated stator core (16) having coil bars (20) and has at least one stator winding head board (24) having an insulating main body (28). In order to reduce the axial length of the stator (8), according to the invention, conducting tracks (26) are integrated into the insulating main body (28), wherein the at least one stator winding head board (24) lies on an end face (23) of the laminated stator core (16) and wherein the conducting tracks (26) are integrally bonded to the coil bars (20).

Abstract: A method for producing an annular active part of an electric machine, where the active part has ring segment-shaped sections with grooves for receiving electric conductors, an electric machine with the ring segment-shaped section, a mill with the electric machine, and a service method for such an electric machine or such a mill, and where the goal is to assembly the electric machine inexpensively.

Abstract: The novel squirrel-cage rotor should enable a power output of the motor of more than 1 MW even at rotation speeds of more than 10,000 rpm. To this end, the conductor bars (4) of the squirrel cage are soldered into slots (8, 9) arranged on the periphery of the massive rotor core (3) across their entire length, and the conductor bars are arranged to be flush with the surface (13) of the rotor core (3).
