Study of a Bidirectional Proportional Electromagnet

Abstract:

Aim to fulfill the design requirements of a pneumatic proportional directional valve, a novel bidirectional proportional electromagnet with integrated lineal Hall position sensor was proposed. Magnetic circuit model and finite element model were established separately. Both static force vs. armature stroke characteristic and Hall sensor output vs. armature position were tested on a newly designed test platform. The experimental result shows a good linear magnetic spring characteristic of the proportional electromagnet, which further ensures a unique spool auto reset capability for directional valves. The mass of the armature is considerably reduced, thus it will benefit the overall performance of high speed pneumatic proportional directional valves.
