Title:
DEVICE FOR INDUCTIVE ENERGY TRANSFER
Document Type and Number:
WIPO Patent Application WO/2012/126465
Kind Code:
A3
Abstract:
A device for inductive energy transfer between a stationary three-phase primary system and a mobile three-phase secondary system is designed in a magnetically symmetrical form with magnetic flux paths of equal length in the three phases and a correspondingly approximately constant power transfer. A stationary iron core part and two mobile iron core parts (3, 5) which are connected electrically in series are each designed as an equilateral triangle or as a star which spans an equilateral triangle and has limbs (3a, 3b, 3c; 5a, 5b, 5c) of equal length which run at the same angle in relation to one another, and supporting posts (3ay, 3by, 3cy; 5ay, 5by, 5cy) which start from the ends of said limbs, and also primary and secondary windings (4, 6) which are arranged at the same distance from one another. The two stationary iron core parts (3) are connected at the respective supporting posts (3ay, 3by, 3cy) by means of magnetic rails (2) which run in parallel and on which the mobile iron core part (5) can roll or be positioned with the aid of ferromagnetic running rollers (7) which are accommodated in recesses (8) in the mobile supporting posts (5ay, 5by, 5cy). The device of simple design has a high degree of efficiency in respect of energy transfer. In the case of energy transfer only in the inoperative state, a stationary iron core part and a mobile iron core part can also be positioned directly one on the other without magnetic rails.
