The system must be cooled to 50 millikelvins to minimize thermal vibrations, which interfere with the cantilever’s magnet-induced displacement signal.

This paper proposes a servo control system for permanent magnet synchronous machine (PMSM) based on Application Specific Intelligent Power Module (ASIPM) and Digital Signal Processor (DSP).

Magnetic-inductive linear position sensors with analog output provide a signal that is proportional to the position of the positioning magnet and cover measuring ranges of up to 200 mm.
