MULTI-TURN ANGLE POSITION SENSOR (EXTENDIBLE FOR MORE THAN 10 TURNS) |
| 摘要 |
A multi-turn non-contact sensor includes a rotationally mounted driver magnet, and a rotationally mounted driven magnet. The driver magnet has a first number (P1) of magnetic poles and is configured to selectively receive a rotational drive torque and, upon receipt of the drive torque, to rotate about a first rotational axis. The driven magnet is spaced apart from, and is coupled to receive a magnetic force from, the driver magnet. The driven magnet has a second number (P2) of magnetic poles and is responsive to rotation of the driver magnet to rotate about a second rotational axis that is parallel to the first rotational axis. The driven magnet rotates one complete revolution each time the driver magnet rotates a predetermined number (N) of complete revolutions, P2>P1, and N=(P2/P1). |

1. A multi-turn non-contact sensor, comprising:
a rotationally mounted driver magnet configured to selectively receive a rotational drive torque and, upon receipt of the drive torque, to rotate about a first rotational axis, the driver magnet having a first number (P1) of magnetic poles; and a rotationally mounted driven magnet spaced apart from, and coupled to receive a magnetic force from, the driver magnet, the driven magnet having a second number (P2) of magnetic poles, the driven magnet responsive to rotation of the driver magnet to rotate about a second rotational axis that is parallel to the first rotational axis, wherein the driven magnet rotates one complete revolution each time the driver magnet rotates a predetermined number (N) of complete revolutions,
P2>P1, andN=(P2/P1). |
