It is an electromagnetic actuator with high responsiveness and bidirectional operation, capable of also functioning as an intrinsically safe explosion-proof structure.
The voice coil motor (VCM) is an electromagnetic actuator that achieves high responsiveness and bidirectional operation. Therefore, by combining it with a driver circuit, it enables various movements that are not possible with conventional solenoids. 【Features】 ■ Can also be used as an electromagnetic actuator with an intrinsic explosion-proof structure ■ 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 lightweight construction and 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 performing closed control in combination with sensor circuits and drivers, precise movements can be achieved.

basic information
【Characteristics】 ■ The "Thrust: Current" characteristic has a good precision proportional relationship. ■ The "Thrust: Stroke" characteristic is constant. ■ The inductance is low. 【Other Applications】 ■ Shortening both lead wires of the coil can achieve a damping effect. ■ It is also possible to generate electricity. ■ Can be used as an electromagnetic actuator with an intrinsic explosion-proof structure, as it possesses a large amount of energy from permanent magnets, allowing thrust generation even with small currents. ■ Not only used as an actuator but also applicable as a sensor. ■ We also offer a MM (Moving Magnet) type VCM that does not experience repeated stress on the lead wires.
