Vacuum Linear Voice Coil Motor Displacement Stage - Fast Response Frequency, Suitable for Semiconductor Applications

Voice coil linear motors, also known as Lorentz motors or scanner motors, are named for their structure resembling the coil of a loudspeaker. They are a fast-response direct-drive motor with zero hysteresis and zero cogging effects, featuring high frequency response, high acceleration, high speed, good force characteristics, easy control, small size, and high resolution. Abroad, voice coil motors are considered excellent servo drives. Depending on the configuration of the drive, feedback, controller, and control algorithm, voice coil motors typically achieve motion frequencies of 500-1000 Hz, even higher.

The oscillating voice coil motor utilizes the technology of the rectangular series products, bending them to form a certain angle for positioning, which meets the requirement of angular oscillation. The RS series can provide an oscillating angle of 90 degrees and a torque of up to 50 N-m. The oscillating voice coil motor products are applied in laser technology for mirror positioners, oscillating valve brakes, oscillating positioning, and flight controllers, involving the semiconductor industry, automation, and aerospace industries. The oscillating voice coil motor is also known as a "galvanometer."

Voice coil motors come in cylindrical, rectangular, and pivot-angle types, which are common, but voice coil motors can be customized with special structures. You can integrate the magnet as part of the housing, position the coil elsewhere, or alter the coil shape, and modify the magnet into a special structural form—all of which are achievable. Often, people get stuck within this limited scope, but voice coil motors can be improved to meet your specific requirements.
