Despite the fact that the energy losses in the beam pumping motor systems (BPMS) utilized in oil fields represent a monumental challenge industrially, very few studies discussed the feasibility and applicability of a universal energy saving technology for such industry. This study proposes a sectional control strategy integrating variable frequency (VF) with voltage regulation (VR) based on the mechanical load characteristics of the BPMS. Main merits of the proposed strategy are as follows: 1) controlling horse-head acceleration through VF, and indirectly weakening the inertia torque of polished rod load, thereby reducing the power consumption during the up-stroke; and 2) based on monitoring load conditions in real time, auto-tracking VR is adopted to optimize the online efficiency of the system. The proposed strategy utilized the adaptive fuzzy logic control to alternate between VF and VR modes. The proposed energy saving strategy was applied to a CYJ10 BPMS driven via a 37-kW induction motor in simulation and experimental environments. Results revealed that the effectiveness of the proposed strategy to improve the load balance effects through better utilization of the counterbalance during the heavy-loading conditions in up-stroke. Furthermore, the energy consumption is reduced via the auto-tracking of VR under light-loading conditions during the down-stroke. Moreover, the energy saving ratio is more than 10% under different dynamic liquid levels and counter weights. The effectiveness of the proposed strategy is verified through comparing the calculated results with the measured data for a standard oil rig, and the generality is verified as well.

“…The load torque varies strongly from a high positive value to a high negative value in a cyclic manner, with an average torque that is much smaller than the peak. This highly cyclic load variation not only affects the energy consumption but also the system sizing [13]- [18]. In the modern looms, high speed is a key element hence, the power consumption becomes an essential factor.…”

This paper presents the dynamic modeling and analysis of an electric motor with integrated magnetic spring (EMMS) when it is coupled to a weaving loom application. The EMMS can provide the majority part of the oscillating part of the load in a passive way by the magnetic spring. The electric motor provides the average torque and the remaining oscillating part in an active way. This reduces the energy consumption. To create an accurate dynamic model for the EMMS, lookup tables are generated from a finite element model (FEM). Further, a 4-bar linkage mechanism is employed to emulate the behavior of the shedding mechanism of a real weaving loom application. Eventually, the whole system dynamic model was created in Matlab environment. Moreover, a complete experimental setup was constructed to validate the effectiveness of the proposed dynamic model and the EMMS behavior. It is shown that the proposed dynamic model effectively predicts the performance of the EMMS system. Besides, it is proved that the EMMS can effectively reduce the energy consumption of the weaving loom application. The amount of reduction in the energy consumption depends on the designed magnetic spring. For the considered application, it can reach 57%.

Cyclic loads such as weaving looms have an oscillating load torque profile which negatively affects the motor size and power consumption. In this paper, a novel electric motor with an integrated magnetic spring (EMMS) is proposed for cyclic loads. The magnetic spring provides the majority of the oscillating part of the load torque in a passive way, thereby reducing the power consumption. Besides, the design and analysis of the proposed EMMS are investigated for a weaving loom application. Moreover, the optimal design of the EMMS is manufactured and various measurements are obtained to validate the principle of the EMMS. It is found that the EMMS can effectively deliver about 40% of the load torque in a passive way. Interestingly, the amount of the delivered torque by the magnetic spring depends on the design choice. For a given load torque, the higher the part of the torque delivered by the magnetic spring is, the lower the power consumption from the supply will be. However, this increases the manufacturing cost of the EMMS. Therefore, the torque of the magnetic spring is a design choice that is a compromise between the investment cost of the EMMS and the total cost of ownership.
