A new technique is proposed to measure mechanical torque of rotating machinery via computer processing.

Abstract

A new technique is proposed to measure mechanical torque of rotating machinery via computer processing. This aim is pursued performing an FFT-realisation of a differentiating FIR-filter by which the sampled speed step-like waveform, produced during a start-up transient of the motor, is processed. The derivative of the speed signal is executed directly in the frequency domain, so avoiding preventive manipulations of the step-like waveform in the time domain. Optimal results have been achieved from the point of view of processing speed and of reduction of the noise level.
