Low Power Consuming Electromagnetic Actuators for Pulsed Pilot Stages

Authors: Z. Zhang, M. Honarpardaz, J. Derkx, A. Trangärd, J. Larsson


Pilot stages are one of the most common positioners and regulators in industry. In this paper, we present two novel concepts for pilot stages with low power consumption to regulate a pneumatic device. Pilot 1, first concept, is designed based on a conventional frame core electro-magnetic actuator and a leaf spring to control the air flow and pilot 2 has an axisymmetric actuator and spring made of non-oriented electrical steel. Concepts are simulated in a system modeling tool to study their dynamic behavior. Both concepts are prototyped and tested. Experimental results are comprehensively analyzed and compared. The most promising concept that consumes less than 8 mW is highlighted and presented.

Keywords: low power consumption, electro-magnetic actuator, multidisciplinary system, pilot stage
