If door magnet signal line is connected, the user can see which door is open and which door is closed at a glance.

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).
