Application of a bending type segment permanentmagnet actuator

C.C.Hong

A bending type design and application presented for the construction of segments permanent magnet (PM) actuator made up of thin plastic strip with segment PM, rectangular PM and support. The strip consists of one layer good bending functional plastic sheet and PM segments under the action ofmagnetic force, thus obtain amaximumcenter deflection of bending plastic strip. The N45H (sintered neodymium-iron-boron) material is used for the segment PM and rectangular PM. The purpose of this paper is to investigate the center deflection of thin plastic strip with segments of PM under bending. The center deflection performs as the stroke length in the segment PM actuator. The important of this paper might be contributed to the innovation of mechanical part designs. The segment PM actuator can produce stroke length with its own magnetic energy.
