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.
Claims61
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 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.
10 The method of claim 1 and further comprising creating a substantially closed magnetic path including a magnetic air gap of less than approximately 0.005 inches between the core housing and the armature.
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;
- and
- a coil positioned in the core housing, the coil receiving a magnetization current to create a substantially closed magnetic path between the armature 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
- 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.
A method of braking a first element with respect to a second element, the method comprising:
- providing a first level of power to a coil in order to create a first irreversible residual magnetic force between a core housing and an armature, the first level of power not saturating the core housing and the armature;
- and
- substantially preventing the first element from moving with respect to the second element due to the first irreversible residual magnetic force.
