“…The configuration of the pulse input range and the pulse rating settings of the torque sensors in the WT5000 strongly influences the torque and speed values. Therefore, a zero balancing as described in [10] of the torque transducer and null function as mentioned in the user manual of Yokogawa WT5000 is required as shown in Figure 3 and Table 3.…”

Torque measurements that account for the influences of temperature and rotation are vital in determining the efficiency of rotating electrical machines on test benches. During experimental efficiency measurements, the influences of temperature and rotational speed generate errors in the torque measurements that could also affect the overall traceable efficiency measurement on test benches. In this paper, experimental efficiency mapping results with a focus on the influence of rotation and temperature on torque measurements are presented.

“…First approaches to the traceability of dynamic torque were presented in [9]- [9], where an oscillatory (sinusoidal) regime was applied to the measurement system through a frequency range sweep, followed by the frequency domain analysis of the data. This method evaluates both the amplitude and phase responses of the device under calibration.…”

The traceability of the torque quantity finds a gap when there is a regime with torque variation rates. The traditional calibration methods define the references to be on the static regime, with null torque rates. This paper presents a method for providing torque traceability to rotating sensors under high torque variation rates. The principle of applying acceleration pulses to rotating shafts, with mounted reference discs with known mass moments of inertia thereon, is presented herein, followed by a description of sequential proceedings for obtaining an analysis in the time domain. The development of the uncertainty budget is also discussed. Demonstrative experimental data is used in order to ratify the principle and to maintain a qualitative approach to the theoretical description of these methods. The research gives a very good idea of the necessary different future approaches to guarantee traceability for mechanical quantities.

“…Thomas [4] carried out a sinusoidal torque calibration using the laser interferometric method, and initially realized the calibration of a sinusoidal excitation torque with a maximum frequency of 100 Hz and amplitude of 100 N•m. Then, Georg et al [5] realized the calibration of the torque sensor under a dynamic torque and rotation conditions, respectively. Zhang et al [6] developed a dynamic torque calibration device with a calibration range of 0.1-200 N•m and a maximum frequency of 100 Hz.…”

A circular grating angle encoder is a key component in the dynamic torque calibration system. To improve the accuracy of an angle measurement, in this paper, the source of the angle measurement error of the circular grating is analyzed; an eccentricity error model and an inclination error model are proposed, respectively; further, these two models are combined to establish a total error model. Through the simulation study with the models, the conditions, in which the eccentricity error or inclination error can be ignored, are discussed. The calibration and compensation methods of the angle measurement error are given, and a progressive error compensation function which integrates the first harmonic fitting and the second harmonic fitting is obtained. An experiment is performed to verify the proposed calibration and compensation methods. The peak-to-peak value of the compensated angle measurement error of the single reading head can be reduced by about 93.76%, which approximates to the error of the mean value of the double reading heads. The experimental results show that the error calibration and compensation method based on the proposed error model can effectively compensate the angle measurement error of the circular grating with a single reading head, and obtain a high-precision measurement angle.
