Voice Coils

Voice-Coils

High power to mass ratio, high acceleration

Low to no hysteresis and zero backlash / cogging

No contact between coil and core movement to avoid friction and wear, maximising life cycle

Cylindrical or Planar Type

Motion Control Products supply a range of cylindrical and planar voice coil motors which are, in effect, direct drive linear motors that can positioned at high speed with high acceleration depending on the application requirements. The voice coil motor can be controlled by a digital servo drive, coupled with suitable feedback it is the ideal solution for short-distance high speed positioning, position, velocity or force controlled sinusoidal oscillation and constant force application.

  • Zero backlash, zero hysteresis and zero cogging
  • Low coil mass with very fast response and high bandwidth
  • No contact between coil and core movement (no wear and tear)
  • Smooth motion at low speeds with limitless resolution (depends on feedback device)

Due to their versatility, Voice Coils can be found in a myriad of applications, such as: Optical lens focusing, pick & place machines, industrial sewing machines, hydrualic and pneumatic proportional valve control and surgical equipment.
