Abstract

This paper presents the research on the influence of coil parameter on the force of DC electromagnetic actuator. The coil parameter discussed in the paper is the angle between the windings. The research method is based on analyzing the magnetic path of DC electromagnetic actuator and on comparison of analytically obtained results with the numerical simulation results. Transient numerical simulation of DC electromagnetic actuator has been performed on the 2D axial-symmetric model using the Finite Element Method (FEM). The main contribution is the coil winding angle impact on the force of DC electromagnetic actuator. The results showed that, by reducing the coil winding angle, it is possible to increase the electromagnetic force, reduce the coil dimensions, and thus the dimensions of electromagnetic actuator.

Summary

Introduction

Solenoid electromagnetic actuators are electromechanical devices which convert electrical energy to mechanical energy related to linear motion [1] and [2]. They are characterized by their compact size and simple structure. When developing an EMA, Transient numerical simulation of DC electromagnetic actuator has been performed in ANSYS Desktop Electronics software, on the 2D axial-symmetric model, using Finite Element Method (FEM). When electromagnetic force overcomes the initial force of the return spring, the plunger starts to move, which is the beginning of the transient period. Electromotive Force (EMF), which opposes to the voltage source and causes the current drop, is induced in the coil due to change of linkage magnetic flux. Stopping period starts when the plunger touches the core and finishes the movement, EMF disappears and current continues to increase
