US 2025/0260348 A1 · EDDY CURRENT BRAKE FOR LINEAR DRIVES

Abstract

A linear eddy current brake includes a brake plate and a moving rotor with magnets having magnet surfaces which generate inductions in the brake plate and induce eddy currents about the magnet surfaces. The brake plate is divided by slots in the brake plate into open segments insulated from one another which reduce the brake force of the eddy current brake (WBS). The open segments are electrically connected or short-circuited to increase the braking force of the WBS. The eddy currents of the segmented brake plate (S-brake plate) flow in the respective open segments and in a conductor region which connects the open segments on one face. The S-brake plate is functionally divided into a securing region, contact region, induction region, and a conductor region, and the regions of the S-brake plate, except the conductor region, are divided into segments which can be short-circuited by slots running in the transversal direction.
