ABSTRACT:
It comprises a cylinder (2) forming the rotor body, extended on each side by the shaft (1), and eight curved permanent magnets (3A to 3H) disposed on the cylindrical surface of the rotor body (2). The magnets (3A to 3H) are secured by adhesive bonding to the rotor (2) and because of their shape leave between them, in the axial direction, V-shaped interstices (a to h). A thread (5) of carbon fibers passes in succession in each of the interstices (a to h) a plurality of times, applying compression forces to the inclined faces of the magnets (3A to 3H), which are thus firmly held against the rotor. The interstices are then filled with a resin to obtain a continuous cylindrical surface.
