Abstract
The electromagnetic machine (1) includes a tubular duct (3 ) intended to receive a conducting material which can circulate in the duct (3) around the core (4) and an inductor (2) arranged coaxially around the duct (3). The inductor (2) includes a magnetic circuit (15) formed by laminated sheet metal combs (18) and windings (14 ) arranged in annular notches (5 ) made in the magnetic circuit (15). The notches (5) are separated from each other by teeth. The teeth of the inductor have lengths in the axial direction which are smaller in the central part of the inductor (2) than in the end parts. The notches (5) are less deep at the ends than in the central part and enclose windings having a smaller number of turns. The windings (14) are each connected to one phase of a polyphase current source.
