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 a irreversible residual magnetic force between the core housing and the armature.
Claims72
A method of latching a first element to retain engagement with 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 axially with respect to the second element due to the irreversible residual magnetic force.
A latch for retaining a first element in engagement with a second element, the method comprising:
- a core housing coupled to one of the first element and the second element;
- an armature positioned adjacent the core housing, the armature coupled to one of the first element and the second element;
- and
- a coil positioned adjacent 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 retain the first element engaged to the second element.
A latch for use in retaining a first element engaged to a second element, the latch comprising:
- electromagnetic assembly means for forming a substantially closed magnetic path, the electromagnetic assembly means coupled to the first element;
- and
- controller means for providing a magnetization current to the electromagnetic assembly means in order to create an irreversible residual magnetic force and to retain the first element engaged with the second element.
