“…In order to adapt this PLL to our application, we propose to modify the original structure by producing a normalized signals with amplitude ±1, regardless of the sensor used and its position. The normalization is possible if the signals v α and v β have the same amplitude, which is not the case with the filters (18). The same output amplitude is obtained by:…”

A PLL-Based Online Estimation of Induction Motor Consumption Without Electrical Measurement

This work is supported by a company wishing to develop new products in the field of energy monitoring in industry. It concerns the real-time estimation of the electrical consumption of an asynchronous motor without electrical measurement. The challenge consists of estimating the characteristic quantities of the motor (speed, torque, powers, efficiency) with only one vibratory measurement, information on the nameplate and commercial documentation available online. To obtain a real-time estimate, traditional FFT analysis is replaced by a PLL initially designed for power grid analysis. So, the second challenge is to modify this PLL for use with vibratory measurement characterized by a low signal-to-noise ratio, amplitude variations and a non-stationary behavior. A complete design and experimental tests are presented to validate the proposed approach.

“…If these data are not available, the characteristic P m = f (N m ) can be approximated by the slip method. In the same way, the efficiency curve can be approximated from models, database or standards [16][17][18][19]. One important point is the sensitivity of these two models to the accuracy of the speed estimation.…”

“…The increasing demand for the use of small AC motors has stimulated research related to the development and enhancement of techniques for the measurement of the motors' efficiency, and for the computation of the associated accuracy [18][19][20][21][22][23][24][25][26][27][28], where we provide a short review of the related research papers. In Reference [9], a comparative analysis of direct and indirect efficiency estimation techniques was presented for a 3 kW, three-phase induction motor, and it was concluded that the direct determination of efficiency should be used for all sizes of induction motors.…”

“…The authors recommended the use of the direct method rather than the indirect method for three-phase motors with power ratings ≤1 kW. In Reference [20], the authors proposed the use of a combination of genetic algorithms to estimate the efficiency of an induction motor, where the uncertainty for a rated output power of 3 kW, was only 0.3%, which was within the acceptable range of accuracy. In Reference [21], the same authors showed that the difference between the measured efficiency (direct method) and the efficiency estimated by the authors' technique (indirect method) was only 0.25%, for a rated power of 3 kW.…”

Experimental Study for the Assessment of the Measurement Uncertainty Associated with Electric Powertrain Efficiency Using the Back-to-Back Direct Method

Brushless electric motors are used intensively in the industrial automation sector due to the motors low inertia and fast response. According to the International Electrotechnical Commission, IEC 60034-2-1, the efficiency of a three-phase electric machine (excluding machines for traction vehicles) can be determined by direct or indirect techniques. In the case of small traction motors (<10 kW), direct methods are used extensively by manufacturers, even if no standard has been published or scheduled by the IEC. In this paper, we evaluated the accuracy of the (direct) back-to-back method for the estimation of the energy performance of a 3 kW brushless AC electric motor used in a light electric vehicle. We measured the efficiencies of a pair of motors and inverters, as well as the overall efficiency of the entire power train. The results showed that the methodology was sufficiently accurate and comparable with other indirect methods available in existing literature. Moreover, we developed a Simulink model that used the powertrain efficiency map as the input to perform the simulation of a standard urban driving cycle. The simulation was run 500 times to calculate the probability density function associated with the total range of the vehicle, considering the uncertainty of the efficiency that was determined experimentally. The simulation results confirmed the low deviation of the distribution standard compared to the average value of the range of the vehicle.

“…Constructing different operating points under different test conditions and using pulse-width modulation technology to control the excitation can also produce satisfactory results [17]. Going further, the genetic algorithm has been applied to induction motor efficiency estimation by the DC test, voltages, currents, input power, and speed measurements [18].…”
