Voice Coil Motor (VCM) using permanent magnets
Electromagnetic actuator with high responsiveness and bidirectional operation.
The voice coil motor (VCM) is an electromagnetic actuator that achieves high responsiveness and bidirectional operation. As a result, it enables various movements that are not possible with conventional solenoids when combined with driver circuits. 【Features】 ■ Generates force by utilizing the interaction between the magnetic field produced by permanent magnets and the current flowing through the coil. ■ Linear bidirectional operation. ■ The movable part is the coil, allowing for weight reduction and thus high responsiveness. ■ Due to the good linearity of the "thrust: current" characteristic, it can be used in open control when combined with a return spring mechanism. ■ By combining with sensor circuits and driver circuits for closed-loop control, precise movements can be achieved.
