Rotary Voice Coil Actuators (VCA)

  • Wide range of torque and excursion angles
  • Various mechanical mounting options available
  • Arc-segment and cylindrical designs available

Rotary voice coil actuators (VCA) are ideal for high acceleration applications that require angular movement. There are two types of designs available: Cylindrical and arc-segment. Cylindrical models are typically used in long stroke applications, whereas arc-segment designs are better suited for short stroke and precise positioning. Rotary actuators feature all of the inherent advantages of VCA technology, such as direct-drive, zero backlash and cog free operation for accurate motion, as well as high acceleration and the use of single phase.
