Analysis of High Force Voice Coil Motors for Magnetic Levitation
Actuators, 2020 A voice coil motor is a simple and linear electromagnetic actuator. Since it has a non-contact force and very low stiffness, it is widely used for precision positioning devices including magnetic levitation systems. During magnetic levitation, high force

Space Mapping Optimization of a Cylindrical Voice Coil Actuator
IEEE International Conference on Electric Machines and Drives, 2005., 2005 An optimal design problem of an electromagnetic actuator is formulated by defining the set of design variables, the constraints, and the optimality criterion. Solving such a problem is a difficult and time-expensive task when many variables, constraints, and conflicting objectives are involved, and when high accuracy is required.

Optimization design of a voice coil actuator based on improved SOM [PDF]
2011 International Conference on Applied Superconductivity and Electromagnetic Devices, 2011 Voice coil actuator is a new kind of direct drive motor. It has many good performances, such as high acceleration and fast response. We present an improved sequential optimization method (SOM) and dimension reduction optimization method to design optimization a cylindrical voice coil actuator in this work.

Driving complex flow waveforms with a linear voice coil actuator. [PDF]
Biomicrofluidics, 2019 Oscillatory and pulsatile fluid flows for use in microfluidic applications were generated using a deformable chamber driven by a low cost linear voice coil actuator. Compliance in the fluidic system originating in the deformable chamber and the fluidic tubing produced a strong frequency dependence in the relationship between the system’s input and the ...

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.

Voice Coil Actuator for Active Vibration Isolation in Microgravity
, 2001 Many microgravity experiments require very low levels of acceleration which cannot be achieved on the International Space Station due to the residual vibration. A vibration isolation system is then usually devised between the experiment and the space station to obtain the desired accelerations at the experiment level.
