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 low 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, and even higher.
The oscillating voice coil motor utilizes the technology of the rectangular series products, bending the rectangular series products to form a certain angle for positioning, meeting the requirements 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 "shutter motor."
Voice coil motors come in cylindrical, rectangular, and tilt angles, which are common, but they can be customized with special structures. You can integrate the magnet as part of the casing, place the coil in a different location, or modify the coil shape and the magnet into a special structure. Often, people get stuck within this scope, but voice coil motors can be improved according to your specific requirements.
