OFF AXIS SENSOR SYSTEM |
| 摘要 |
An angle sensor device includes first and second magnet tracks, a sensor component, and a control unit. The first and second magnet tracks are fixed to a rotatable object and are configured to generate a non-homogenous field. The rotatable object is configured to rotate about a rotation axis and the non-homogenous field has a smaller gradient of magnitude along a rotational direction than a perpendicular direction, which is perpendicular to the rotational direction. The sensor component is positioned off-axis and is configured to measure a magnetic field including the non-homogenous field and provide magnetic field measurements. The control unit is configured to determine angular information from the magnetic field measurements. |

1. An angle sensor device comprising:
first and second magnet tracks fixed to a rotatable object and configured to generate a non-homogenous field, wherein the rotatable object is configured to rotate about a rotation axis and the non-homogenous field has a smaller gradient of magnitude along a rotational direction than in a perpendicular direction, which is perpendicular to the rotational direction; a sensor component positioned off-axis and configured to measure a magnetic field including the non-homogenous field and provide magnetic field measurements; and a control unit configured to determine angular information from the magnetic field measurements. |
