Design and Optimization of a Voice Coil Motor With a Rotary Actuator for an Ultrasound Scanner

Abstract

This paper proposes a new application for the rotary voice coil motor (VCM). In developing a low-cost ultrasound scanner for the developing world, an oscillating transducer is required to sweep over the skin. The ultrasound scanner must operate from a USB power supply in remote locations. The application requires a 3.3-N force on the coils of the motor to… (More)
