1Abstract-In this paper, we present a wireless instantaneous
torque measurement system based on MEMS accelerometers
and high frequency RF transmitter. We develop this system for
instantaneous torque and speed measurement on machine rotary
shafts. Real time data are transmitted to the DSP board that is
used to implement traditional vector control of an induction
motor. It can be applied to any rotating system to identify and
analyze torque ripple. Experiments are carried on direct startup
and under vector control to prove the effectiveness and accuracy
of this wireless torque measure
