Abstract
A rotor of an electrical machine designed as a permanently excited synchronous machine includes a rotor base body having pocket-like recesses and permanent magnets positioned in the pocket-like recesses and poles which, viewed in a circumferential direction, are arranged alternately next to one another and form pole pairs. In a region of each pole, radially inner pocket-like recesses with radially inner permanent magnets arranged therein form a radially inner permanent magnet group and radially outer pocket-like recesses with radially outer permanent magnets arranged therein form a radially outer permanent magnet group. In a region of the respective radially inner and respective radially outer permanent magnet group, a first longitudinal center axis of a permanent magnet accommodated in a respective central pocket-like recess extends perpendicularly to a partly curved line which extends in a radial direction of the rotor and centrally divides the respective pole in the circumferential direction.
