Voice Coil Motor Driver Market

Voice Coil Motor Driver Market: Introduction

• Voice coil motor, or VCM, is a type of electrical motor; it consists of magnetic housing and coil. The voice coil is utilized as an actuator where positioning with high speed or acceleration is required.
• These linear actuators use a magnetic housing and coil to provide linear force without contact between the moving and fixed world. The voice coil converts electrical signals directly into linear magnetic force, providing much higher purity of motion, as compared to DC motors that require separate drivetrains such as belts or gears. When combined with a position sensor, voice coils provide quick, accurate movement with excellent repeatability. The polarity of the voltage determines the transition direction of the motor.
• Since the mass of the moving coil is typically low, the speed and acceleration of the VCM is very high and the settling time is very short. Moreover, low inductance of a VCM leads to low electrical time constant, which enables the VCM to have a highly rapid response and bandwidth.
• Therefore, VCMs have been widely applied to various small range positioning applications. Voice coils stages are used for short travel ranges, typically on the order of 25mm (1 inch) or below.
• Voice coil motor drivers are used to precisely control the electric current in the coil, the magnetic force (Lorenz force) and thus, acceleration, velocity, and position can be varied, very accurately. A feedback sensor – usually a linear encoder – provides the current position information to a closed-loop controller that compares target and actual position and varies the current accordingly to minimize the error.

Rise in Demand for VCM due to Increase in Demand for Fast Quick Actuating Devices

• A high degree of precision has become an essential requirement for positioning systems for the last few years owing to the development of related industries. Increasing demand for fast and accurate actuation in devices and precise motion applications are a few key factors that are expected to boost the global voice coil motor market during the forecast period.
• VCM helps decrease magnet leakage and has contactless electromagnetic interaction with other types of electronic devices
• Applications such vibrators, camera lens focusing, valves, speakers, computer peripherals and drives, and precision machining tools are traditional applications for VCM
• Investments in medical and robotics sectors have been increasing for the last few years, which in turn is boosting the demand for VCMs due to their precision quality. Voice coil actuators offer numerous advantages in applications such as medical valve actuators, instruments used in spectroscopy, and chromatography.
• For instance, voice coil motors are being increasingly utilized to control the valves in ventilators for patients who have difficulty in breathing. VCAs, when instrumented with position encoders, can achieve an exceptional level of performance when coupled with appropriate driver electronics and closed loop servo control.

North America to Hold Prominent Share of Global Market

• North America is projected to account for a prominent share of the global market during the forecast period owing to an increase in consumer applications such as smartphones, digital cameras, medical devices, and small handheld devices. Increasing advancements in automation in homes and infotainment systems are also key factors that are projected to drive the VCM driver market in the region during the forecast period.
