Abstract

A találmány tárgya osztott mágnesű forgórész, amelynek csavarvonalalakú helyett lépcsősen ferde hornya van. A lépcsősen ferde horonylehetővé teszi egyenes vonalú mágnesek (44) alkalmazását, amelyekbehelyezhetők a forgórész (20) hasítékaiba (38), és ezáltalszükségtelenné válik csavarvonal alakú kalitka előállítása. Alépcsősen ferde horony hatékonyan csillapítja az állórész hornyainakszámától függő felharmónikusokat. Ezen túlmenően a lépcsősen ferdehornyú forgórész (20) egyes kiviteli alakjai nyitott hornyokkal vannakkiképezve és ezáltal a forgórész hídjában nem alakul ki telítés. ÓThe subject of the invention is a split-magnet rotor, which instead of having a helix shape has a stepwise inclined groove. The step-inclined groove enables the use of straight-line magnets (44) which can be inserted into the slots (38) of the rotor (20), thereby eliminating the need to produce a helical cage. A stepped inclined groove effectively dampens harmonics depending on the number of stator grooves. In addition, some embodiments of the staggered bevel groove rotor (20) are equipped with open grooves and thus saturation does not develop in the rotor bridge. HE
