Targeting applications that include fast valves in respiration equipment, auto-focus capabilities in optical systems, and active damping in instrumentation, the LA50-65-001A voice-coil actuator ...

Need smooth motion, high speed and acceleration, or tight servo control? Voice coil actuators, providing rotary or linear motion, may be the solution you need. Here is a look at choosing the right ...

Aerotech’s XL4s linear amplifier for closed-loop servo control of voice coil and single-phase motors eliminates the nonlinearities common with PWM amplifiers. The unit provides deterministic behavior, ...

Claimed to operate both cog and hysteresis free, the model LA15-16-020A is a two-wire, non-commutated direct drive linear voice coil servo actuator. With a diameter of 1.5" and ...

Details are at the shutter website and described in the paper Enhanced laser shutter using a hard disk drive voice-coil actuator, Rev. Sci. Instrum. 78 026101 (2007). The shutter, and variations based ...

Voice coil actuators provide numerous benefits to the engineer. VCAs are simple and highly robust while also offering exact precision based on their input. VCAs accelerate smoothly and quickly to any ...

Voice coil actuators are direct-drive electric motors that provide limited linear or rotary motion. They are often used in applications requiring proportional and tight servo control, such as ...
