Abstract: A rotor (1) for an electric machine, in particular a permanently excited synchronous machine. At least one recess (20) is formed on the outer wall (12) of the receiving space (6) and forms a non-magnetizable space (29) adjacent to the lengthwise surface (10) of the permanent magnet (7). Due to this non-magnetizable space (29), iron losses in the stator teeth can be reduced in particular during operation of the electric machine in the field weakening range, which may result in a rise in efficacy of up to 3% for the electric machine.

Abstract: The invention relates to an electric asynchronous machine (1), in particular an induction machine, comprising: —a cylindrical stator (2) with stator teeth (22) on a stator yoke (21), wherein a ratio between a yoke height (hy1) of the stator yoke (21) in the radial direction and a groove height (hn1) of the stator grooves (23) in the radial direction ranges from 1.75 to 2.5; —a cylindrical rotor (4) with poles (42) on a rotor yoke which are defined by short-circuit windings in a rotor body (41), wherein a ratio between the yoke height of the rotor body (41) in the radial direction and the groove height of the rotor grooves in the radial direction ranges from 2 to 2.75.

CPC classification number: H02K1/2766
Abstract: The invention relates to a rotor (1) of an electric machine (2), said rotor comprising a rotor body (4) which can be rotated about a rotor axis (3) and which, with respect to a cross-section, has a plurality of rotor poles (5) each having a pole center axis, (6) wherein; a plurality, in particular all, of the rotor poles (5) have a two-layer magnet assembly (7) comprising a plurality of magnets (8), in particular permanent magnets; each magnet assembly (7), as viewed in the radial direction with respect to the rotor axis (3), comprises an inner layer (10) of at least three magnets (8) and an outer layer (11) composed of two magnets (8); the inner layer (10) forms a radially outwardly open arc; the outer layer (11) is designed such that the distance between the magnets (8) of the outer layer (11) increases radially outwards; and the magnets (8.2) of the inner layer (10), which are outer with respect to the pole center axis (6), and the magnets (8) of the outer layer (11) each have an angle of inclination (α2, α1) with respect to the pole center axis (6), which angle of inclination is formed between the pole central axis (6) and an axis of inclination (12) of the magnet (8) in question.
The rotor is characterized in that:
the magnets (8) of the radially outer layer (11) are arranged in such a manner that a point of intersection (S1) of the axis of inclination (12) of the magnets (8) of the radially outer layer (11) with the pole center axis (6) lies radially inside the radially inner layer (10); and
the angle of inclination (α1) of the magnets (8) of the radially outer layer (11) is designed to be smaller than the angle of inclination (α2) of the outer magnets (8.1) of the radially, inner layer (10).-
