Global Voice Coil Actuators (VCA) Market: Overview
Voice coils were developed for loud speakers for the conversion of electrical energy into sound wave through the use of a diaphragm originally. Voice coil actuators (VCAs) are direct drive, limited motion devices that utilize a permanent magnet field and coil winding (conductor) in order to produce a force that is proportional to the current applied to the coil. These non-commutated electromagnet devices are used in linear and rotary motion applications which require linear force or torque output, as well as high acceleration or high frequency oscillation. Voice coil actuators are direct-drive, hysteresis-free devices used for providing highly accurate linear or rotary motion. Voice coil actuators are being constantly used in applications where proportional or tight servo control is a necessity. Voice coil actuators are a type of direct drive mechanism that provides extremely precise positioning over small displacements. Voice coil actuators are very controllable, repeatable as well as predictable with low hysteresis. VCAs have been used in many other applications to supply precision linear or rotary motion. Such actuators also provide desirable attributes, such as low hysteresis, no cogging or detent, high acceleration and force, and a long life cycle. VCAs, when instrumented with position encoders, can achieve an exceptional level of performance when coupled with appropriate driver electronics and closed loop servo control.
Global Voice Coil Actuators (VCA) Market: Drivers and Restraints
Increasing use of voice coil actuators (VCAs) for precision motion applications, need for high reliability and fast actuation are some of the primary factors driving the growth of the global voice coil actuators (VCA) market. The VCA greatly reduces the magnet leakage and has less electromagnetic interference with other electronic devices. One of the important limitation of voice coil actuators (VCA) is that huge costs are incurred. This is one of the factors hampering the growth of voice coil actuators (VCA) market. Efforts are being taken by many companies to upgrade their research and development activities to introduce innovations in this field.
