FIELD: machine building; electrical engineering.
SUBSTANCE: machine (20) includes stator (24) and rotor (26), which is made with possibility of rotation relative to stator (24). Rotor (26) includes shaft (28) having paramagnetic shell (36) with cavity (40) formed therein, and magnet (30) at least partially located in said cavity (40). Feature of the invention is the design of magnet (30) freely floating in cavity (40) and having a shape complementary to said cavity (40) so that magnet (30) and paramagnetic shell (36) are rotationally interlocked with each other. Cap (38) closes magnet (30) in cavity (40).
EFFECT: higher reliability and manufacturability.
