Title:
RELUCTANCE ROTOR WITH RUNUP AID
Document Type and Number:
WIPO Patent Application WO/2014/166555
Kind Code:
A3
Abstract:
The invention relates to a rotor (10) for a reluctance motor, wherein the rotor (10) has a laminate stack (14) having layers (16), each of which has a plurality of flux-conducting sections (24) formed in each case by a magnetically conductive rotor lamination (18) and extending transversely to a corresponding q axis (30), wherein the flux-conducting sections (24) are separated from one another by nonmagnetic flux barrier regions (22). The invention is based on the problem of providing the rotor (10) with a runup aid. For this purpose, an electrically conductive and non-ferromagnetic filler material is arranged in a plurality or all of the flux barrier regions (22) of the layers (16), by means of which filler material the flux barrier regions (22) of adjacent layers are electrically connected to one another so that cage bars (34) of a rotor cage of the rotor (10) which extend axially parallel or skewed with respect to the axis of rotation (A) are formed by the filler material in the flux barrier regions (22).
