A rotating magnetic field generator based on permanent magnets

Abstract

The invention relates to a rotating magnetic field generating device based on a permanent magnet, the device comprises a driving mechanism, a first bracket, at least one permanent magnet, and a secondbracket, wherein the driving mechanism drives the first bracket to rotate, the at least one permanent magnet is mounted on the first bracket, and a receiving seat is mounted on the second bracket, and the receiving seat is located in a magnetic field formed by the at least one permanent magnet. The positions of the first permanent magnet, the second permanent magnet and the receiving seat can beadjusted, facilitating the formation of magnetic fields of different directions and intensities, the magnetic fields are stable and reliable, at the same time, the first permanent magnet and the second permanent magnet are driven by the step motor, Industrial cameras can capture clear images at different mounting heights, which is easy to operate, cheap in cost, excellent in performance and stability, and greatly improves the experimental environment of the current magnetic-controlled flexible robots, simplifying the experimental research in the field of magnetic-controlled flexible robots andon the like.

Description

technical field [0001] The invention relates to the fields of bionic flexible robots and experimental science, in particular to a rotating magnetic field generator based on permanent magnets. Background technique [0002] High-speed, precise, and lightweight flexible robots have many advantages, such as small size, high working speed, low energy consumption, large load-to-mass ratio, and compact mechanism. Magnetically controlled flexible robot is a new, effective and convenient control driving method, which provides the necessary guarantee for the flexible movement of the robot. Small magnetically controlled soft robot experiments require a magnetic field with sufficient strength and flexible direction changes. [0003] At present, it is almost difficult to find this type of device that is ready-to-use on the market. The changing magnetic field device generated by alternating current is expensive and bulky. Under the same volume, the magnetic field strength is smaller than...

[0003] At present, it is almost difficult to find this type of device that is ready-to-use on the market. The changing magnetic field device generated by alternating current is expensive and bulky. Under the same volume, the magnetic field strength is smaller than that formed by a permanent magnet.
