Voice coil positioner

Motion Control – Miniature Parallelogram Stage Forestville, CA – Motion Control Components – The PVS-5.5 Parallelogram Voice Coil Stage from Equipment Solutions is a complete, compact high performance positioning system. Compared to galvos and voice-coil systems, piezo-driven active optic mounts are typically more compact, fieldless, faster, inherently stiffer, and more predictable when power is cut. Lower current requirements mean reduced ohmic losses and heat production, and cabling is thinner and more tractable. Fast Voice Coil Actuators with Frictionless Air Bearings / Flexures Zero Wear, Velocity to 1000mm/sec, to 25mm Travel, to 70N Force These voice coil actuators uses frictionless bearings – either flexures for short travel, or air bearings for extremely straight guiding. Both drive and guiding systems are wear free and clean room compatible.

Voice coil synonyms, Voice coil pronunciation, Voice coil translation, English dictionary definition of Voice coil. stepper motor. Translations. English: stepper motor n Schrittmotor m.

The voice coil motor works as a linear actuator to pressurize the fuel, and thus the amount of injected fuel and the injection timing can be controlled by the driving current of the coil.
A voice coil was free to move between the steel insert and the permanent magnets within the casting. A current in this coil would draw the coil into or out of the positioner assembly, and thereby move the read/write heads of the disk drive in much the same manner as in a loudspeaker.

Voice coil actuators are, technically, non-commutated DC motors. The term "voice coil" is often used because one of their first applications was to vibrate the paper cones in loudspeakers. Rotary voice coil actuators are also referred to as "arc segment" actuators or "limited angle torque motors" because they produce arc-shaped motion.
Applying a voltage across the terminals of the motor causes the motor to move to one direction. Reversing the polarity of the applied voltage will move the motor to the opposite direction. The generated force is proportional to the current that flows through the motor coil. This force is almost constant in the specified stroke range of the motor. Voice coil motors do not need commutation and using a position sensor, positioning accuracies of less than one micron or 0.00004 inches are achievable.
