SensorPlot™ can be used to observe the characteristics of power transmission components ranging from the couplings of a motion control system to a gearbox in an industrial application.

Compliance and Mechanical Resonance

Mechanical resonance is often observed as vibration, and can cause a control loop to become unstable. Complex loads can introduce multiple resonant frequencies.

Coupling Resonance

Couplings Introduce Velocity Errors

Coupling misalignment can introduce periodic velocity ripple. In the graph below, velocity is plotted versus angular position over one revolution. Notice that the velocity error is periodic and repeats twice per revolution.
