Abstract

A magnetically continuous winding includes a first coil and at least one additional coil substantially fixed in place in at least one direction with respect to a position of the first coil. A core formed by a resin is applied to the first coil and the at least one additional coil to substantially bind the first coil and the at least one additional coil.

First claim

What is claimed is:

1 . A magnetically continuous winding, comprising:
a first coil; at least one additional coil substantially fixed in place least one direction with respect to a position of the first coil; and a core formed by a resin applied to the first coil and the at least one additional coil to substantially bind the first coil and each additional coil.

2 . The magnetically continuous winding of claim 1 ,
wherein the first coil and the at least one additional coil are formed in a distributed winding.

3 . The magnetically continuous winding of claim 1 ,
wherein the first coil and the at least one additional coil are insulated.

4 . The magnetically continuous winding of claim 1 ,
wherein the coils and the core form a block.

5 . The magnetically continuous winding of claim 4 ,
wherein the block has a shape that allows the block and at least one other block to be substantially interlocked so as to form a continuous winding.

6 . The magnetically continuous winding of claim 5 ,
wherein the block and the other block are spaced from each other so as to provide tolerance for thermal expansion.

7 . The magnetically continuous winding of claim 5 ,
wherein the block and the other block are joined using substantially identical joints.

8 . The magnetically continuous winding of claim 5 ,
wherein the block and the other block are fastened to the same guide.

9 . The magnetically continuous winding of claim 8 ,
wherein the block and the other block are positioned along a track.

10 . The magnetically continuous winding of claim 1 ,
wherein the resin is applied by placing the coils in a mold and using transfer, injection, compression, or vacuum pressure impregnation.

11 . The magnetically continuous winding of claim 1 ,
wherein the resin comprises a polymer-based liquid that is applied to the first coil and the at least one additional coil and solidified.

12 . The magnetically continuous winding of claim 1 , further comprising:
a spacer to maintain a physical separation between a first coil and one of the at least one additional coils.

13 . The magnetically continuous winding of claim 4 ,
wherein a force is generated when voltage is applied to the block.

14 . The magnetically continuous winding of claim 13 ,
wherein voltages up to 8410 volts are applied to the block.

15 . The magnetically continuous winding of claim 1 ,
wherein the mold serves as insulation for the first coil and the at least one additional coil.

16 . The magnetically continuous winding of claim 1 ,
wherein the resin has a thermoclass F characteristic.

17 . The magnetically continuous winding of claim 1 ,
wherein the magnetically continuous winding is used as a fixed component in a low pressure transportation system in cooperation with a rotor fixed to a pod that travels through the substantially vacuumed transportation tube.

18 . The magnetically continuous winding of claim 17 ,
wherein the low pressure transportation system is a substantially vacuumed transportation tube.

19 . The magnetically continuous winding of claim 1 ,
wherein the magnetically continuous winding is a component in a linear motor.

20 . A method of producing a magnetically continuous winding, comprising:
fixedly aligning a second coil in place with a first coil in at least one direction; applying a resin to the first coil and the second coil to substantially bind the first coil and the second coil.

21 . The method of claim 20 ,
wherein a spacer is used to substantially fix the coils in relation to each other and the edges of the block

22 . The method of claim 21 ,
wherein the first coil and second coil and spacers are co-molded within the resin.

23 . The method of claim 20 ,
wherein the first coil and second coil are placed in a mold and the resin is applied by transfer, injection, compression, or vacuum pressure impregnation.
