A voice coil motor is a highly controllable actuator suitable for applications that require limited displacement. The VCM consists of a coil assembly and a permanent magnetic field assembly. This non-commuted electromagnetic device is employed in applications of linear and rotary motion that require linear force or torque output and high frequency actuation or high acceleration. The interaction between the magnetic fields of the coil and the gap gives rise to linear force that acts on the coil. Conventionally, most of the VCMs were similar to the design of a loud speaker. However, the newer designs use lower densities of magnetic field, longer axial length gaps, and shorter coils with fewer wire turns.
A voice coil is the wind of wire attached to the tip of a loudspeaker cone. A magnetic field is generated by driving a current through the coil. The magnetic field enables the voice coil to react with the field from a permanent magnet that is fixed to the frame of the speaker, which thereby moves the cone of the speaker. Further, by applying an audio waveform on the voice coil, the cone reproduces sound pressure waves that correspond to the original input signal. Voice coils provide the cone with motive force through the reaction of magnetic field and the current that passes through it.
The voice coil motors has less electromagnetic interference with the other devices and greatly reduce the magnet leakage. Growth in adoption of high-precision positioning stages has driven the market for voice coil motors. However, high cost incurred is a restraint that hampers the growth of the market.
The global voice coil motor market is segmented based on type, coil type, and application. The types of VCM include linear VCM and rotary VCM. By coil type, the market is bifurcated into overhung coil and underhung coil. Based on application, the market is sub-divided into shaker, lens focus, servo valve, speaker, positioning stage, and others. Further, it is analyzed across North America, Europe, Asia-Pacific, and LAMEA.
Linear VCM is the simplest type of electric motor that consists of a magnetic housing and a coil. Rotary VCMs help in the applications that need acceleration and angular movement.
Some of the key players operating in the market include Physik Instrumente, H2W Technologies, Sensata Technologies, Motion Control Products Ltd, Motran Industries Inc., Dura Magnetics, Dat Cam Automation, MotiCont, SMAC Corporation, and Equipment Solutions, Inc.
