Abstract

A system having vehicles, each including a secondary coil for the inductive supply of the vehicle from a primary conductor system, wherein the secondary coil includes a coil core, which has at least one main limb, the secondary coil being made up of a first and a second coil, each composed of windings which enclose the main limb in each case, the first coil arranged such that the windings are connected in series, and the induction voltage arising at the coil corresponds to the sum of the individual voltages induced at all windings when the magnetic flux enclosed by an individual winding in the main limb always has the same direction, especially in each winding of the first coil, the second coil arranged such that the second coil is made up of a first type of windings, i.e., a first partial coil, and of a second type of windings.

First claim

The invention claimed is:

1. A system, comprising:
at least one vehicle;
a primary conductor system; and
a secondary coil for inductive supply of the vehicle from the primary conductor system;
wherein the secondary coil includes a coil core, which has at least one main limb having an axis, the secondary coil being made up of a first and second coil, which are formed of windings which enclose a main limb in each case by winding around the axis,
wherein the first coil is arranged such that windings are connected in series, and an induction voltage arising at the first coil corresponds to a sum of individual voltages induced at all windings when a magnetic flux enclosed by an individual winding in the main limb always has a same direction;
wherein the second coil is composed of a first type of windings and of a second type of windings, the windings connected in series, and an induction voltage arising at the second coil corresponds to a difference of a summation voltage of all individual voltages induced at the windings of the first type, and to a summation voltage of all individual voltages induced at the windings of the second type, when a magnetic flux enclosed by an individual winding in the main limb always has a same direction, wherein the second coil surrounds the first coil, and wherein the first type of windings of the second coil and the second type of windings of the second coil are wound in opposite directions from each other and connected in series with respect to one another.

2. The system according to claim 1 , wherein the coil core has a center limb pointing toward one of a floor and a ceiling.

3. The system according to claim 1 , wherein the first type of windings corresponds to a first partial coil and the second type of windings corresponds to a second partial coil, and wherein the first partial coil and the second partial coil of the second coil are set apart from one another in a direction of the main limb.

4. The system according to claim 1 , wherein the first type of windings corresponds to a first partial coil and the second type of windings corresponds to a second partial coil, wherein a center limb is arranged between the first and second partial coils of the second coil, and wherein the center limb points toward a floor.

5. The system according to claim 1 , wherein side limbs are arranged at ends of the main limb such that the coil core has one of (a) an E-shape, (b) a C-shape, and (c) a U-shape, a open side pointing toward a floor.

6. The system according to claim 1 , wherein the first coil includes at least two partial coils.

7. The system according to claim 1 , wherein the first type of windings corresponds to a first partial coil and the second type of windings corresponds to a second partial coil, and wherein at least one of (a) the first and (b) the second partial coil of the second coil includes at least two partial coils.

8. The system according to claim 1 , wherein the first type of windings corresponds to a first partial coil and the second type of windings corresponds to a second partial coil, and wherein the first and the second partial coil of the second coil are arranged in identical size and have a same number of windings.

9. The system according to claim 1 , wherein the secondary coil is compensated by a capacity, connected in series, such that an associated resonant frequency corresponds to a frequency of an alternating current impressed on the primary conductor.

10. The system according to claim 1 , wherein the first type of windings corresponds to a first partial coil and the second type of windings corresponds to a second partial coil, and wherein the first and second partial coils are provided in individually compensated form.

11. The system according to claim 1 , wherein the vehicle is movable moved along a primary conductor of the primary conductor system at an angle of less than 50.degree. relative to a direction of movement.

12. The system according to claim 1 , wherein the vehicle includes an energy store, so that the vehicle at times is movable independently of the primary conductor system.

13. The system according to claim 1 , wherein the vehicle includes a position detection system, whose signal is suppliable to control electronics of the vehicle, which controls a drive of the vehicle, a path being determined, in a manner that takes into account regions in which the primary conductor system is installed, for energy-optimized execution of transport operations within the system.

14. The system according to claim 1 , wherein the vehicle includes a data exchange connection to a central computer of the system.

15. The system according to claim 1 , wherein the vehicle includes a track guidance system cooperating with the primary conductor system, and an anti-collision system.

16. The system according to claim 1 , wherein the coil core includes the main limb and omits a center vertical limb.
