Title:
RELUCTANCE ROTOR LAMINATION HAVING AN OPENING FOR STRESS REDUCTION
Document Type and Number:
WIPO Patent Application WO/2015/113656
Kind Code:
A3
Abstract:
The invention relates to a reluctance rotor lamination that permits easy assembly of a rotor, in particular by means of press fitting, wherein there must be sufficient stability. For this purpose, a reluctance rotor lamination (18) is provided, wherein an opening (6, 42) for stress reduction is arranged on each d axis half (32) in each flux-conducting section (24), such that a partial flux-conducting section (36, 37) is formed on each of the two sides of each d axis half (32) in each flux-conducting section (24). The sum of the smallest cross-section of each of the two partial flux-conducting sections (36, 37) is substantially greater than or equal to a smallest cross-sectional area of the flux-conducting section (36, 37) perpendicular to each partial d axis half (32) radially above the opening, such that the opening (6, 42) does not cause magnetic impairment.
