Abstract
A magnet for a magnetic angle sensing system, the magnet having a tapered geometry in parallel with a rotation axis of the magnet, and configured to be mounted to a rotatable member such that a thin end of the magnet is closer to a magnetic field sensing element located on the rotation axis than a broad end of the magnet.
Claims20
A magnet for a magnetic angle sensing system, comprising:
- a pyramidal geometry that is symmetrical with respect to a rotation axis of the magnet,
- wherein the magnet is a one-piece magnet homogeneously magnetized diametrically with respect to the rotation axis, and is configured to be mounted directly to a rotatable member such that a thin end of the magnet is closer to a magnetic field sensing element than a broad end of the magnet, and the magnetic field sensing element is centered above the thin end of the pyramidal geometry such that the rotation axis passes therethrough.
A magnetic angle sensing system, comprising:
- a magnetic field sensing element configured to sense a magnetic field;
- and
- a magnet that is rotatable at a rotation axis and with respect to the magnetic field sensing element, is a one-piece magnet homogeneously magnetized diametrically with respect to the rotation axis, and has a pyramidal geometry that is symmetrical with respect to the rotation axis with a thin end located closer to the magnetic field sensing element than a broad end, and wherein the magnetic field sensing element is centered above the thin end of the pyramidal geometry such that the rotation axis passes therethrough.
