Characteristics Analysis and Test of a Voice-Coil-Type LOA Considering the Push/pull Effects

Push/Pull Effect를 고려한 보이스코일형 LOA의 특성해석 및 시험

Abstract

The effect of the coil flux, so called "push/pull effect", is to shift the airgap flux density variation due to the magnet alone by a certain amount. Thrust therefore is shift downward or upward. The push/pull effect was presented through the FEM analysis and static tests. We compared with the thrust obtained through the FEM analysis and static tests.
