I am using an electric motor to impose displacements on a specimen,
but when the motor is on, there is too much noise in the displacement
and force signal.
Everything seems to be nice when the motor is off. The frequencies
of the noise are less than 10Hz, too low to be filtered. In addition,
I am sure that each cable is effectively shielded with the same ground cable.
Does a motor, in my case, which is a Permanent Magnet Synchronous
Motor (AC), always introduce noise like that? How can I reduce it?
I will greatly appreciate your help.
