Design and Simulation of Novel 3-DOF Spherical Voice Coil Motor
Actuators, 2021 Multi-DOF motion is realized in the eyes and joints of robots mostly through the combination of multiple one-degree-of-freedom (1-DOF) motors. However, this results in reduced efficiency, a large volume, reduced response speed, and inaccurate positioning.

Design and Optimization of a Voice Coil Motor With a Rotary Actuator for an Ultrasound Scanner
IEEE Transactions on Industrial Electronics, 2015 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
