AI Technical Summary

Technical Problem

Existing drive systems suffer from significant slippage and inefficiencies due to changes in friction coefficients and icing, particularly in contact-based systems like rolling rubber wheels, leading to energy wastage and loss of control.

Method used

A drive system utilizing a rotatable disc with permanent magnets and a sword-shaped pole structure that generates propulsive force through magnetic reluctance and eddy currents, allowing slip-free movement and efficient energy use by switching between reluctance and eddy current principles based on speed.

Benefits of technology

Enables smooth, slip-free operation with high tractive force and precise angle control, reducing energy consumption and maintaining efficiency across varying conditions.

Abstract

The system comprises a first part and a second part arranged to be relatively movable relative to the first. wherein the first part comprises a sword part (2) extending in the direction of movement, in particular of an elongated design, wherein the second part comprises at least one rotatably mounted, driveable disk, the axis of rotation being oriented perpendicular to the direction of movement, wherein the disk has permanent magnets (20, 21) on its circumference, the magnetization direction of which is oriented radially or in a direction opposite to the radial direction, wherein the magnetization direction of each permanent magnet (20, 21) is opposite to the permanent magnet (20, 21) nearest in the circumferential direction, wherein the sword part (2) has a pole structure along the direction of movement such that the propulsive force can be generated when the permanent magnets (20, 21) rotate past the pole structure, wherein the pole structure has ferromagnetic regions (40) that are uniformly spaced apart from each other in the direction of movement, wherein the ferromagnetic areas (40) are designed to be wider towards the axis of rotation of the disk.
