dc motor

A fully house voice coil actuator (VCA) further expands upon the idea of the semi-housed VCA that incorporates self-aligning bushings and a shaft. This design fully captures the coil assembly to maintain concentricity with the field assembly. An added internal flex circuit protects external moving wires and limits axial travel on both ends of the stroke.

As a single piece, the linear actuator can be mounted on one side and does not require a customer supplied alignment system, making it easy to integrate into applications. Housed voice coil 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 use of single phase.

  • Designs available with magnet springs and/or latches
  • Different shaft options available
  • Housing offers additional mechanical and environmental protection
  • Single unit that is more easily integrated into customer applications
  • Life tested in excess of 500 million cycles
