Abstract
This chapter presents the development of a Micro Electro Mechanical System (MEMS) gyroscope-based sensing module and the experiments to verify the functionality of the sensing module in a rotating mechanism. The module integrated a MEMS gyroscope sensor, battery, microprocessor, signal processing circuitry, analog-to-digital converter, memory unit, remote switch to turn on/off the module operation, and signal output port. It has no wire connection for power supply and signal transmission, which avoids the wire twisting problem during spindle rotating test. The module is then firmly secured on a rotating platform to test its function. The measured angular velocities are verified the accuracy through the encoder readout of the driving motor. Also, using this sensing module to detect a rotating plate with intentionally run-out error setting, the acquired signals clearly exhibit the corresponding relationship. The preliminary results demonstrate the feasibility of the developed sensing module for dynamic characterization of rotating mechanism. © 2013 Springer Science+Business Media New York.
