Rotary actuators utilize a rectangular linear actuator and bending heat technology to provide high resolution to form a preferred angular positioning system. Rotary actuators are commonly used as mirror position actuators for laser technology, rotary valve actuators , rotary positioning systems and flight control actuators, Rotary actuator markets include semiconductor, automotive, industrial and aerospace industries.
Application scenarios for rotary voice coil motors in mirrors are as follows:
In composite axis tracking systems, rotary voice coil motor-driven mirrors act as fast tilting mirrors (FSMs) to compensate for optical path shifts caused by carrier vibration or target motion, enhancing tracking accuracy in scenarios such as laser communication and weapon targeting.
Rotary voice coil motors are used in astronomical telescopes or laser launching systems to compensate for beam aberrations caused by atmospheric turbulence or mechanical deformation by adjusting the mirror angle in real time, restoring imaging quality or beam directivity.
In industries such as laser cutting and lithography, the rapid deflection of mirrors is controlled for beam scanning, focus position correction or pattern generation.
Rotary type voice coil motor Light weight of moving coil, short response time, high frequency.
