Abstract

Voice coil actuators (VCAs) are applied in a fast steering mirror (FSM), precision positioning platform, etc. These applications demand that the VCAs used are simple, inexpensive, reliable, and efficient. In this paper, we report a novel VCA with concentration flux-line structure. The VCA greatly reduces the magnet leakage and has less electromagnetic interference with other electronic devices. The output force sensitivity of the VCA is 4.17 N/A with a coil of 300 turns and the stroke is ±2.5 mm. Driven by this VCA, the mechanical scanning angle of the FSM can achieve ±4.9 deg when the scanning frequency is 100 Hz.
