Abstract
The invention relates to a permanent magnet rotor (1) for an electronically commutated DC Motor, comprising a shaft (2), a rotor sheet packet (3, 3') supported by the shaft, which rotor sheet packet comprises close to the periphery thereof completely closed and tangentially extending rectangular recesses (4) for receiving planar permanent magnet plates (5, 5', 5''). At least one permanent magnet plate (5, 5', 5'') is accommodated in each case in each recess, the permanent magnet plates (5, 5', 5'') are held by spring elements (6) free of play by force locking, the recesses (4) have free spaces (7, 7') connected to the permanent magnet plates (5, 5', 5'') in the tangential direction, which free spaces extend across the major part of the side surfaces (8) of the permanent magnet plates (5, 5', 5'') and the rotor sheet packet (3, 3') consists essentially of a radial outer annular region (9) and a radial inner core region, wherein the annular region (9) in a large part is delimited by the recesses (4) and the free spaces (7, 7') and is integral with the core region (10) via thin radial webs (11). The problem addressed by the invention is to simplify the producibility and to increase the mounting safety, without affecting the magnet circuit. According to the invention, said problem is solved by the characteristic of the claim (1).
