Study of electromagnetic field distribution and force characteristics of a DC electromagnetic actuator with T-shaped armature

This paper studies a solenoid DC electromagnetic actuator with T-shaped armature. Using the finite element method, a computer model has been developed in the software product Comsol Multiphysics for studying the 3D magnetic field and the force characteristics of the actuator. Comparison has been made with results, obtained for an actuator with E-shaped core and flat armature and with experiment.
