A rotor designed as a reluctance rotor includes a laminated core which defines an axis and has end faces. The laminated core includes sheets which are at least partly axially layered, with the sheets having flux-conducting portions and flux-blocking portions to form a specified number of poles. A cage made of electric conductors runs in a substantially axial direction and is connected at the end faces of the laminated core by short-circuit rings. The conductors are located in a radially outer region of at least some of the flux-blocking portions arranged one behind another substantially in the axial direction, with the conductors defining conductor bars formed by conductive material at a quantity determinative to define an internal diameter of the conductor bars.

Rotor of a synchronous reluctance machine

A rotor for a reluctance motor includes a laminate stack having layers. Each layer has a plurality of flux-conducting sections formed in each case by a magnetically conductive rotor lamination and extending transversely to a corresponding q axis. The flux-conducting sections are separated from one another by nonmagnetic flux barrier regions. An electrically conductive and non-ferromagnetic filler material is arranged in a plurality or all of the flux barrier regions of the layers to electrically connect the flux barrier regions of adjacent layers to one another so that cage bars of a rotor cage of the rotor which extend axially parallel or skewed with respect to the axis of rotation are formed by the filler material in the flux barrier regions.

Reluctance rotor with runup aid

The invention relates to a rotor () for a reluctance machine (E), wherein the rotor () has a laminate stack () with layers (), each of the layers having a plurality of flux-conducting portions () which are formed in each case by a magnetically conductive rotor lamination () and extend between two adjacent d-axes and transversely to a respective q-axis (), wherein the flux-conducting portions () are separated from each other by in each case a flux barrier () which is filled with a casting compound. The aim of the invention is to additionally provide a permanent magnetic excitation in the rotor () without degrading the reluctance of the rotor. To this end, the invention provides that the casting compound comprises permanently magnetic particles () in one or more or each of the flux barriers ().
