Rotor for a permanently excited synchronous motor and permanently excited synchronous machine

摘要

Rotor (1) for a permanently excited synchronous machine, the rotor (1) comprising a rotor body (2) with at least one recess (3), which is essentially in an axial direction, at least partially through the rotor body (2), and at least two permanent magnets (4 ', 4 ", 4"'), wherein the recess (3) at least two in the circumferential direction of the rotor body (2) longitudinally extending first regions (5 ', 5 ", 5"'), in each of which a permanent magnet (4 ', 4 ", 4'") and at least one is inserted into a radial direction extending second region (6 ', 6 "), and the rotor body (2) between the inserted permanent magnet (4', 4", 4 "') in the form of a radial web (7', 7") in the second region (6 ', 6 ") of the recess (3) that extends between the radial web (7', 7") and the rest of the rotor body (2), a gap (8 ', 8 ") is formed and the radial web (7', 7") in such a free end (9 ', 9 "), wherein the free end (9', 9") of the radial web (7 ', 7 ") a geometric widening (10', 10"), and wherein the gap (8 ', 8 ") between the radial web (7', 7") and the rest of the rotor body (2) with a magnetically non-conductive material is filled.n="13"
