Abstract
A multi-axis motor includes a first elongate magnet member disposed in a first orientation and a second elongate magnet member disposed in a second orientation orthogonal to the first orientation and mechanically coupled to the first elongate magnet member. The first elongate magnet member is operable to adjust a first axis of a fine axis structure. The second elongate magnet member is operable to adjust a second axis of the fine axis structure.

A method for using a multi-axis motor, the method comprising:
- adjusting a first axis of a first motor by moving a first magnet member in a first coil, wherein:
- the first magnet member is coupled with a support structure;
- an optical device is coupled with the support structure;
- the first magnet member is an elongate magnet member having a length and a width;
- the length of the first magnet member is greater than the width of the first magnet member;
- and
- the first magnet member is curved along the length of the first magnet member;
- adjusting a second axis of the first motor by moving a second magnet member in a second coil, wherein:
- the second magnet member is coupled with the support structure;
- the second magnet member is an elongate magnet member having a length and a width;
- the length of the second magnet member is greater than the width of the second magnet member;
- the second magnet member is curved along the length of the second magnet member;
- and
- the first magnet member and the second magnet member protrude from the support structure at right angles so that the length of the first magnet member is orthogonal to the length of the second magnet member at the support structure;
- and
- adjusting a first axis and a second axis of a second motor, wherein the second motor is for coarse adjustment and the first motor is for fine adjustment of the optical device.
A method for a fine adjustment for a multi-axis motor, the method comprising:
- adjusting a first axis of a motor by moving a first magnet member in a first coil, wherein:
- the first magnet member is an elongate magnet member having a length and a width;
- the length of the first magnet member is greater than the width of the first magnet member;
- and
- the first magnet member is curved along the length of the first magnet member;
- and
- adjusting a second axis of the motor by moving a second magnet member in a second coil, wherein:
- the second magnet member is an elongate magnet member having a length and a width;
- the length of the second magnet member is greater than the width of the second magnet member;
- the second magnet member is curved along the length of the second magnet member;
- and
- the second magnet member is rigidly coupled with the first magnet member.
A method for a multi-axis motor, the method comprising:
- applying a first current to a first coil to generate a first magnetic field to apply a force to a first elongate magnet member, wherein the first elongate magnet member is part of a structure comprising:
- a hub;
- a first magnet;
- a second magnet;
- a first section;
- a second section, wherein:
- the first section is between the hub and the first magnet;
- the first section rigidly couples the first magnet with the hub;
- the first section is iron;
- the first section and the first magnet are part of the first elongate magnet member;
- the second section is between the hub and the second magnet;
- the second section rigidly couples the second magnet with the hub;
- the second section is iron;
- and
- the second section and the second magnet are part of a second elongate magnet member;
- and
- applying a second current to a second coil to generate a second magnetic field to apply a force to the second elongate magnet member.
