Abstract
Residual magnetic locks, brakes, rotation inhibitors, clutches, actuators, and latches. The residual magnetic devices can include a core housing and an armature. 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 braking a first element with respect to a second element, the method comprising:
- forming a substantially closed magnetic path between an armature, at least one plate, and a core housing in order to create an irreversible residual magnetic force;
- and
- substantially preventing the first element from moving with respect to the second element due to the irreversible residual magnetic force.
A brake for use in preventing a first element from moving with respect to a second element, the brake 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;
- at least one plate positioned between the core housing and the armature;
- and
- a coil positioned in the core housing, the coil receiving a magnetization current to create a substantially closed magnetic path between the armature, the at least one plate, and the core housing in order to create an irreversible residual magnetic force and to prevent the first element from moving.
A brake for use in preventing a first element from moving with respect to a second element, the brake comprising:
- electromagnetic assembly means for forming a substantially closed magnetic path, the electromagnetic assembly means coupled to the first element and the second element and including at least one plate;
- and
- controller means for providing a magnetization current to the electromagnetic assembly means to create an irreversible residual magnetic force in order to prevent the first element from moving with respect to the second element.
