ABSTRACT:
A rotary electrical machine for heating a flow of air comprises a primary magnetic circuit suitable for creating a ring of magnetic poles of polarity alternating from pole to pole, and a secondary magnetic circuit suitable for moving relative to the primary magnetic circuit with the circuits being separated by a cylindrical air gap. The secondary magnetic circuit comprises a cylindrical sleeve (1) of laminated ferromagnetic material having a ring of rectilinear notches (4) formed in the vicinity of one of its two cylindrical faces, these notches extending parallel to the axis of the sleeve and being open at both axial ends. Each of the notches receives a zig-zag corrugated copper sheet (6) and the two axial margins (6.sub.3) of each sheet project axially beyond the sleeve and are electrically interconnected with the adjacent margins of the other sheets by two copper rings (8) disposed at opposite axial ends of the sleeve.
