The voice coil motor's performance and applicable place, Tongmao Xiaobian first told everyone that voice coil motor is a special form of direct drive motor, can directly convert electrical energy into linear motion mechanical energy without any intermediate conversion mechanism of the transmission .
Voice coil motor principle is: in a uniform air gap magnetic field into a cylindrical winding, the windings are energized to generate electromagnetic force to drive the load for linear reciprocating motion, change the strength and polarity of the current, you can change the size and direction of the electromagnetic force . Therefore, the voice coil motor can be in the form of a straight line or a rotation.
The voice coil motor has the advantages of high response, high speed, high acceleration, simple structure, small size, good force characteristics, and easy control. In recent years, with the rapid development of voice coil motor technology, voice coil motors are widely used in precision positioning systems and many different forms of high acceleration, high frequency excitation, fast and high-precision positioning motion systems. Compared with coreless linear motor and ironcore linear motor, it can provide better high-frequency response characteristics and can do high-speed reciprocating linear motion, especially suitable for short-stroke closed-loop servo control system. Voice coil motor control is simple and reliable, no reversing device, long life.
Voice coil motor main application areas: semiconductor, optical electronics, automotive production testing, bio-biochemical detection sampling, food and pharmaceutical, assembly packaging, automated testing, high-speed scanning, digital imaging systems, efficient welding, patch, assembly, testing and testing Equipment, optical element handling and inspection, various linear or rotary applications, precision and high-speed motion equipment, especially applications requiring high-speed cyclic reciprocating motion.
