Alternator flux shaping
10581358 · 2020-03-03 · ·

An electric machine includes a stator, a rotor, and magnets. The stator includes multiple flux members having ferrous material. The rotor is configured to rotate relative to the stator and spaced from the stator by an air gap. The magnets are rigidly mounted to the flux members of the stator. At least a first magnet and a second magnet of the magnets includes an elongated axis parallel to a radius of the rotor and a minor axis perpendicular to the elongated axis, and a first pole of the first magnet having a first polarity and positioned along the minor axis to face a first pole of the second magnet having the first polarity.

PERMANENT MAGNET ARRANGEMENT, AXIAL FLUX MACHINE AND ELECTROMECHANICAL DRIVE
20250003277 · 2025-01-02 ·

A permanent magnet arrangement for use as a rotor or stator of an axial flux machine, in particular an axial flux machine of a door drive includes. permanent magnets arranged in a ring-shaped manner around a central axis and each magnetised in an axial direction running parallel to the central axis. Permanent magnets arranged adjacent to each other each have an opposite polarisation. All permanent magnets are configured in one piece and form a multi-pole pair ring magnet.
