Abstract
Residual magnetic locks, brakes, rotation inhibitors, clutches, actuators, and latches. The residual magnetic devices can include a core housing and an armnature. The residual magnetic devices can include a coil that receives a magnetization current to create an irreversible residual magnetic force between the core housing and the armature.
Claims75
A method of coupling a first element to a second element, the method comprising:
- providing a coil attached to a substantially stationary object;
- forming a substantially closed magnetic path between an armature, a core housing, and the substantially stationary object in order to create an irreversible residual magnetic force;
- and
- coupling the first element to the second element due to the irreversible residual magnetic force.
1 more element
A clutch for use in coupling a first element to a second element, the clutch comprising:
- a core housing coupled to one of the first element and the second element;
- an armature positioned adjacent to the core housing, the armature coupled to one of the first element and the second element;
- a coil attached to a substantially stationary object, the coil receiving a magnetization current to create a substantially closed magnetic path between the core housing, the armature, and the substantially stationary object in order to create an irreversible residual magnetic force and to couple the first element to the second element.
A clutch for use in coupling a first element to a second element, the clutch comprising:
- electromagnetic assembly means coupled to the first element and the second element and including a coil attached to a substantially stationary object;
- and
- controller means for providing a magnetization current to the coil to create a substantially closed magnetic path in order to create an irreversible residual magnetic force and to couple the first element to the second element.
