Abstract
A device for providing angular displacement of an axis in a direction selected from the X or Y direction or rotational movement about the Z direction with respect to the axis. The device comprises a magnetic core element which produces a magnetic field and defines a Z axis. The core element is capable of displacement in the X and Y directions respectively, and also rotational movement about the Z axis. A coil device proximate the core element introduces a distortion force in the core element in at least one of the X and Y directions or about the Z axis as desired a mounting device suspends the core element with respect to the coil means to permit relative movement therebetween in response to the distortion force.
Claims28
A device for providing angular displacement of an axis in a direction selected from the X or Y direction or rotational movement about the Z direction with respect to said axis, comprising:
- a magnetic core element producing a magnetic field and defining a Z axis, said core element being capable of displacement in the X and Y directions respectively, and also rotational movement about the Z axis;
- coil means proximate said core element for introducing a distortion force in said core element in at least one of said X and Y directions or about said Z axis as desired;
- and
- mounting means for suspending said core element with respect to said coil means to permit relative movement therebetween in response to said distortion force.
A device for providing angular displacement of an axis in a direction selected from the X or Y direction or rotational movement about the Z direction with respect to said axis, comprising:
- a magnetic core element producing a magnetic field and defining a Z axis, said core element being capable of displacement in the X and Y directions respectively, and also rotational movement about the Z axis;
- a ferromagnetic ring surrounding at least a portion of said core element to produce a distortion force in at least one of said X and Y directions or about Z axis as desired, said ring including a coil wound around a portion of the periphery thereof;
- and
- mounting means for suspending said core element with respect to said coil means to permit relative movement therebetween in response to said distortion force.
The device of claim 21, wherein said magnetic core element is sized to have a length facing said gap and the portion of the periphery 180° radially from said gap and a width shorter than said length to provide increased spacing between said element and said ring proximate said two coils.
