Abstract

The invention discloses a linear current vortex brake apparatus and a linear carrying apparatus. The linear current vortex brake apparatus includes a stator and a mover, wherein the stator includes a substrate and a plurality of conductor sheets which are arranged on the substrate at uniform intervals in the width direction of the substrate; each conductor sheet utilizes a multi-segment structure made of materials with different resistivity; in the brake direction, the resistivity of each conductor sheet is successively reduced in the brake direction; the mover includes a connecting base and a plurality of permanent magnets which are arranged on the connecting base at uniform intervals in the width direction of the connecting base; the thickness of the permanent magnets at two side edges is a half of the thickness of the permanent magnets between the two side edges; the quantity of the permanent magnets is one more than the quantity of the conductor sheets; and the conductor sheets of the stator and the permanent magnets of the mover are respectively inserted into the mutual gaps. For the linear current vortex brake apparatus and the linear carrying apparatus, as a vortex brake apparatus which is made of segmented materials and uses a comb structure is utilized, stronger braking force can be continuously provided.

technical field [0001] The invention relates to a linear electric eddy current braking device and a linear carrying device using the linear electric eddy current braking device. The linear electric eddy current braking device is used for rapid braking of high-speed linear moving objects. Background technique [0002] Traditional linear motion braking methods mainly include mechanical and electromagnetic. [0003] Mechanical braking includes elastic rope braking or hydraulic friction braking, etc. The braking principle is simple and the effect is safe and reliable, but it will cause damage to the braking device, large vibration shock and loud noise during the braking process; [0004] Electromagnetic braking uses electromagnetic methods to convert kinetic energy into electrical energy for power generation. Two types of methods are commonly used. One is to let the linear motor itself enter its electric braking state, and the generated electric energy can be flexibly disposed o...
