Abstract
The present disclosure relates to a variable diameter electromagnetic coil. The coil may include a coil winding containing inner and outer winding layers. The coil may incorporate a first hub including one or a plurality of inner supports, one of the inner supports connected to a location on the inner winding layer. A second hub may then be provided including one or a plurality of outer supports, one of the outer supports connected to a location on the outer winding layer. One of the first or second hubs may be capable of rotating to cause the coil winding to wind or unwind. An interconnect hub may then be provided which may be capable of providing electrical connection to the coil winding.
Claims20
An electromagnetic coil comprising:
- a coil winding containing inner and outer winding layers wherein said coil winding is wound in a first direction;
- a first hub including one or a plurality of inner supports, one of said inner supports connected to a location on said inner winding layer;
- a second hub including one or a plurality of outer supports, one of said outer supports connected to a location on said outer winding layer;
- wherein one of said first or second hubs is capable of rotating to cause said coil winding to wind or unwind;
- an interconnect hub capable of providing electrical connection to said coil winding.
An electromagnetic coil comprising
- a coil winding containing inner and outer winding layers wherein said coil winding is wound in a first direction;
- a first hub including one or a plurality of inner supports, one of said inner supports connected to a location on said inner winding layer and is capable of extending or retracting in a radial direction;
- a second hub including one or a plurality of outer supports, one of said outer supports connected to a location on said outer winding layer and is capable of extending or retracting in a radial direction;
- wherein one of said first or second hubs is capable of rotating to cause said coil winding to wind or unwind;
- an inner interconnect cable and an outer interconnect cable, both attached to said coil winding and to an interconnect hub wherein one of said inner or outer interconnect cables is capable of winding about said interconnect hub in a second direction that is either equal to or opposite to said first direction.
A method of manufacturing a variable diameter electromagnetic coil comprising:
- forming a coil winding containing inner and outer winding layers wherein said coil winding is wound in a first direction;
- positioning a first hub including one or a plurality of inner supports within said coil, one of said inner supports connected to a location on said inner winding layer;
- positioning a second hub within said coil including one or a plurality of outer supports, one of said outer supports connected to a location on said outer winding layer;
- wherein one of said first or second hubs is capable of rotating to cause said coil winding to wind or unwind;
- attaching an inner interconnect cable and an outer interconnect cable to said coil winding and to an interconnect hub wherein one of said inner or outer interconnect cables is capable of winding about said interconnect hub.
