Design of a High Force Voice Coil Motor
Applied Mechanics and Materials, 2013Voice coil motor is an electromagnetic actuator widely used for motion generation. The main weakness of a voice coil motor is small force. In this paper a voice coil motor is mathematically modeled, analyzed and optimized to obtain high force. According to the optimized final designs, the performance of the voice coil motor is evaluated.

Voice coil motor nano stage with an eddy current damper
2008 10th International Conference on Control, Automation, Robotics and Vision, 2008This paper presents a nano positioning mechanism with flexure hinge and damper. The nano stage represented in this paper consists of a leaf spring guides and the voice coil motor (VCM) since it provides long working range and the control is easy. However, when the leaf spring is used alone, mechanism has very small damping, which reduces the system ...

A New Loading Device Driven by Voice Coil Motor
Applied Mechanics and Materials, 2013The mechanical environment has an important influence on biological behavior of the human musculoskeletal system. Either in vivo or in vitro culture, the growth and development of the musculoskeletal tissue depend on the mechanical environment. Now we propose a new loading device which uses a voice coil motor as driving force to further optimize tissue

Development and Application of a High-Thrust Voice Coil Motor
Advanced Materials Research, 2013A Voice Coil Motor (VCM) for precise positioning with high output force was designed. The stability and heat dissipation of VCM were analyzed. The performance of VCM was also compared with that of the same type VCM produced by SMAC. Uniaxial ratcheting behavior of solder wire (Sn63/Pb37) was studied by uniaxial cyclic stress controlled tension ...

Towards a Generation of Ironless Voice Coil Motors
2010Classical voice coil motors for linear displacements are often used in applications that require the force they exert to be a linear image of the current in the coil. However, these devices have drawbacks which are linked to the presence of iron and result in a non linear force. Therefore, this paper presents ironless motor structures.

Evaluation of the dynamic properties of a Voice Coil Motor (VCM)
2007 14th International Conference on Mechatronics and Machine Vision in Practice, 2007The electrical and mechanical characteristics of a voice coil linear motor under moving conditions are evaluated using a method based on the levitation mass method (LMM). The force generated by the actuator is measured as the inertial force of the mass, which is levitated with sufficiently small friction using a pneumatic linear bearing.
