Abstract

A magnet arrangement (10) for a magnetic levitation vehicle (1) is described. The magnet arrangement comprises at least one magnetic pole (11) consisting of a core (14) and a winding (12) applied to the core, a control circuit connected to the winding (12) and a power supply unit for supplying at least the electrical energy required for the control circuit. According to the invention, the magnet arrangement (10) is designed as an autonomous modular unit integrating within itself the magnetic pole (11), the control circuit and the power supply unit (FIG. 5).

Claims

1. A magnet arrangement for a magnetic levitation vehicle (1) comprising:

at least one magnetic pole (11) consisting of a core (14) and a winding (12);

a control circuit (18) connected to the winding (12); and

a power supply unit including a voltage converter (24), for supplying at least the electrical energy required for the control circuit (18);

wherein the magnet arrangement is constructed as an autonomous modular unit in a form of a hollow-bodied magnet back box (15, 15a), within which is integrated the at least one magnetic pole (11), the control circuit (18) and the power supply unit (23, 24;

24, 41;

24, 47); and

wherein the magnet back box (15, 15a) includes drawer-like units (30) into which at least the control circuit (18) and the voltage converter (24) of the power supply unit are disposed and, which is configured to be fastened to a car body (17) of said magnetic levitation vehicle (1).

2. A magnet arrangement according to claim 1, characterized in that the magnet arrangement is constructed of a plurality of magnet poles (11), whose windings (12) are electrically connected in series and connected with the control circuit (18).

3. A magnet arrangement according to claim 2, characterized in that the magnet poles (11) are combined to form at least two groups of magnet poles each group being connected to an associated control circuit (18), and that both control circuits (18) are integral parts of the modular unit.

4. A magnet arrangement according to claim 3, characterized in that the magnet poles (11) form a group each, individually or in pairs.

5. A magnet arrangement according to claim 1, characterized in that the power supply unit comprises a winding (23) of a linear generator at least in one magnet pole (11a), which linear generator winding (23) is connected to a voltage converter (24) of the rower supply unit accommodated in the modular unit.

6. A magnet arrangement according to claim 1, characterized in that the power supply unit comprises at least one pick-up coil (47) for a contact-less inductive transmission of energy.

7. A magnet arrangement according to claim 1, characterized in that the power supply unit comprises of least one current collector (41).

8. A magnet arrangement according to claim 1, characterized in that the magnet arrangement is constructed as a support magnet (5) and/or a guidance magnet (9).

9. A magnet arrangement according to claim 8, characterized in that the magnet arrangement is constructed as a module comprising the support magnet (5) and the guidance magnet (9).

10. A magnet arrangement according to claim 1, characterized in that the power supply unit comprises at least one buffer battery integrated in the modular unit.
