Comparison analysis of the magnetic field and the magnetic force inside of an electromagnetic actuator with the use of an armature measuring sensor

摘要

Common errors in electromagnetic actuators must be reduced in order to meet the increasing requirements in quality and manufacturing costs. In-line magnetic process control is a promising method to avoid a great number of errors in early stages of production. This paper displays the meaningful correlation between the magnetic field and magnetic force characteristics of a proportional magnet. For this investigation, an armature measuring sensor is developed and implemented into a magnetic field test bench, which enables the realization of a so called smart factory.
