Patent Images
1. A rotary electrical machine comprising:
- a rotor provided with a body with an axis, the rotor body comprising a plurality of longitudinal cavities each for receiving at least one permanent magnet; and
magnetic poles each formed by the permanent magnets accommodated in two adjacent cavities forming a “
V”
on a plane orthogonal to the axis of the rotor body,the rotor comprising at least one part for retention of the permanent magnets in the cavities,wherein the retention part comprises two elongate strips, each strip comprising at least one boss which applies a force of retention of the corresponding permanent magnet in the cavity, andwherein the retention part additionally comprises at least two connection arms between the two strips, with the boss extending axially between the two connection arms.

Abstract
The invention relates mainly to a rotary electrical machine comprising a rotor (10) provided with a body (12) with an axis (X), the rotor body (12) comprising a plurality of longitudinal cavities (16) each designed to receive at least one permanent magnet (13);
- magnetic poles each formed by the permanent magnets (13) accommodated in two adjacent cavities (16) forming a “V” on a plane (P) orthogonal to the axis (X) of the rotor body (12);
- the rotor (10) comprising at least one part (35) for retention of the permanent magnets (13) in the cavities (16),
characterised in that the retention part (35) comprises two elongate strips (36), each strip (36) comprising at least one boss (37) which is designed to apply a force of retention of the corresponding permanent magnet (13) in the cavity (16), and in that the retention part (35) additionally comprises at least two connection arms (40) between the two strips (36), with the boss (37) extending axially between the two connection arms.
