US 11,381,181 B2 · System for adjusting alignment and location of a magnet in a mover or other mounting component

Abstract

A system and method for adjusting the alignment and location of a magnet. A first actuator exerts a first applied force to urge the magnet in a first axial direction and a first biasing device exerts a first opposing force. The first applied force and opposing forces are modulated relative to each other to position the magnet at a lateral location. A second actuator exerts a second applied force to urge the magnet in a first angular direction about a pivot axis and a second biasing device exerts a second opposing force. The second applied and opposing forces are modulated relative to each other to position the magnet at a select angular orientation relative to the magnet holder. The magnet is secured to the magnet holder after positioning. The magnet can also be rotated about its geometric centerline to position its magnetic axis.

Dependent claims

An adjustment system for adjusting the alignment and location of a magnet, said system comprising:

a magnet holder;
a magnet carried by the magnet holder;
a first actuator that exerts a first applied force on the magnet to urge the magnet in a first axial direction;
a first biasing device that exerts a first opposing force on the magnet to urge the magnet in a second axial direction opposite the first axial direction;
a magnet fastener that immovably secures the magnet to magnet holder in an operative position.

2 more elements

An adjustment method for adjusting the alignment and location of a magnet relative to at least one of first and second sensor reference positions, said method comprising:

(a) providing a magnet holder and a magnet carried by the magnet holder;
(b) one of:
(i) sensing a magnetic field of the magnet at both said first and second sensor reference positions and adjusting a lateral position of said magnet along an X-axis if respective X-axis components of the magnetic field at both said first and second sensor reference positions have the same sign;
(ii) sensing the magnetic field of the magnet at both said first and second sensor reference positions and adjusting an angular position of said magnet about a pivot axis that is perpendicular to said X-axis if said respective X-axis components of the magnetic field at both said first and second sensor reference positions have opposite signs;
(iii) sensing a magnetic field of the magnet at one or both of the first and second sensor reference positions and adjusting a rotational position of said magnet about a central axis of said magnet;
(c) repeating step (b) until a magnetic axis of said magnet is located at a desired position.
