Voice coils are fundamental electromechanical mechanisms that are used in material handling equipment, gimbals, medical devices, and even interplanetary spacecraft. Each application has used voice coil actuators (VCAs) to supply the precision linear or rotary motion needed for exceptional...

Voice Coil (VC) Actuators are direct-drive, hysteresis-free devices used for providing highly accurate linear or rotary motion. By virtue of their high acceleration and the absence of commuta-. tion, voice coil actuators offer numerous advantages in such applications as medical, semiconductor...

Voice coil motors offer excellent control characteristics where linear actuation is required over short distances with electronic control systems. Comparison of the force characteristics vs displacement, and vs current, for voice coil devices and solenoid actuators shows the difference between...

The question of whether to use voice coil actuators or solenoids for small displacement motion control applications comes up often. This article explains the key differences between each product and why you might choose one over the other for your application. A non-commutated DC linear actuator...

The combination of "coarse" precision screw drives for long distance motion and ultra-high resolution actuators such as piezo and voice-coil-based systems allows combining travel ranges up to hundreds of millimeters with response, smoothness and resolutions not achievable with conventional drives...
