Abstract
Provided is a system for reducing velocity of a conveyance. The system may include a conveyance. A first member of In a linear motor may be attached to the conveyance. A second member of the linear motor may include stator coils. The second member may be separate from the first member and may be separate from the conveyance. The first member may be moveable relative to the second member. A current-interrupting device may selectively shunt at least two coil wires of the stator coils by shorting the at least two coil wires. A method for reducing velocity of a conveyance and a method for making a system for reducing velocity of a conveyance are also disclosed.
Claims22
A system for reducing velocity of a conveyance, comprising:
- a conveyance;
- a first member of a linear motor attached to the conveyance;
- a second member of the linear motor, the second member comprising stator coils, the second member separate from the first member and separate from the conveyance, the first member moveable relative to the second member;
- and
- a current-interrupting device configured to selectively shunt at least two coil wires of the stator coils by shorting the at least two coil wires.
A method for reducing a velocity of a conveyance, comprising:
- moving a first member of a linear motor relative to a second member of the linear motor, the first member attached to a conveyance, the second member comprising stator coils, the second member separate from the first member and separate from the conveyance;
- shunting at least two coil wires of the stator coils by shorting the at least two coil wires;
- and
- inducing an induced current in the stator coils by moving the first member relative to the second member while the at least two coil wires are shunted.
A method of making a system for reducing a velocity of a conveyance, comprising:
- attaching a first member of a linear motor to a conveyance;
- providing a second member of the linear motor comprising stator coils, the second member separate from the first member and separate from the conveyance, the first member moveable relative to the second member;
- and
- coupling a current-interrupting device to the second member, the current-interrupting device configured to selectively shunt at least two coil wires of the stator coils by shorting the at least two coil wires.
