The present disclosure relates to a ring for a rotor of an electric machine as a support for a retaining ring and for cooling coils of the rotor. It is an object of the invention to provide measures for cooling coils of a rotor of an electric machine. Disclosed is a ring for an electric machine, the ring is connected between a retaining ring and coils wound around a rotor, whereas the ring is fabricated from a non-conductive material.

Ring for an electric machine

The present disclosure relates to a chamber for housing strands of a stator bar for electric machines. The problem to provide a reliable chamber for a stator bar of an electric machine is solved with a stator bar chamber engaging a stator bar in an electric machine. The chamber includes a number of hollow conductors in a first straight part of the chamber, a number of hollow conductors in a second tapered part, and a number of hollow conductors and adjacent solid conductors in a third straight part. The first part of the chamber is closed with a ring mounted at the edge of the first part and a nipple adapted to the ring.

Chamber for conductors of electric machines

The method for removing a bar or coil from a slot of an electric machine includes weakening the bonding between the slot and the bar or coil, and then removing the bar or coil.

Method for removing bars or coils from slots of an electric machine

A cutting device for cutting a wedge and/or conductive bar or coils and/or part of thereof within a slot of an electric machine includes a saw with at least a blade, a guide for guiding the saw during cutting, the guide being connectable to the electric machine. The saw and the guide are withheld together preventing their separation.
