The conversion and optimum adaptation of the mechanical torques to the particular application is usually carried out by means of finely graduated reduction gears in rotary drive tasks. High-precision spindles in combination with DC micromotors, brushless DC servomotors or stepper motors make it possible to convert the rotary motion into linear lifting or pulling motions. The ball screws BS 22-1,5 from Faulhaber allows linear movements with minimum path fluctuations of only max. 5 μm over the absolute travel.
The combination with motors and add-on components such as high-resolution encoders, integrated motion controllers or stepper motors in micro-stepping mode enables high precision. Demanding positioning tasks in optical filters, in fiber optic technology, in lens adjustment in optical systems or micro actuators for medical technology are potential fields of application. The mechanical connection to the motors was realized by means of a backlash-free coupling integrated into the spindle. For applications in special applications there are numerous modifications such as variable spindle lengths, adapted spindle nuts or special lubricants on request.
