“…During working of PCPs in different fit modes, the total power consumption can be generally reflected by the shaft power, which mainly consists of the theoretical hydraulic power and the frictional loss power. The former power is linear to the lifting pressure, while the latter power is closely related with the frictional condition between the stator and rotor inside the pump [10]. Therefore, the total power consumption can be given as:…”

The performance of progressing cavity pumps(PCPs)is significantly different in different fit modes between the stators and rotors，such as interference fit for conventional PCPs with rubber stators and clearance fit for novel all metal PCPs. In order to study the influence of fit modes on PCP performance, a novel concept of the fit parameter is introduced to quantitatively describe the fit condition. Based on working principles of PCPs, comprehensive studies are carried out on the pump performance in different fit modes, including the volumetric characteristics, power consumption and work efficiency. The results show that the theoretical pump rate slightly decreases with the increase of the fit parameter. Though there is obvious friction inside the pump and the interference has a great impact on the power consumption, the PCP in interference fit is able to achieve high volumetric efficiency (>80%). Though there is inevitable leakage and the clearance has a significant influence on the flow rate, the PCP in clearance fit can reach high mechanical efficiency (>90%). The novel all metal PCP in clearance fit has enormous potential for development owing to its good overall performance.

This research paper presents an analysis of electric motors performance by the assessment of vibration characteristics caused by bearing faults, housing bearing looseness and rotor unbalance. In this study, an analysis of fault that occurred in electric motor has followed ISO 10816-3 Standard. Bring the used electric motors for testing and measuring the vibration of the electric motors by using the Spectrum Analysis & Field Balancing Analyzer model ADASH A440-VA4 Pro. The vibration results of 22kW, 55kW and 75kW motor imply the malfunction of bearing faults, housing bearing looseness, and rotor unbalance. The results obtained from the analysis will be used as references and guidelines for predictions of faults in the electric motors, including maintenance scheduling of electric motors.

In this paper, active damping control based virtual positive impedance for a PMSM driver is proposed. The proposed model is assumed to achieve the better motor current with a better harmonic response. 6 switches can be employed in the design of the driver to obtain high performance with a simultaneous reduction in the motor current harmonics and thus the torque ripple of PMSM. However, the reduction of input current harmonics is very important to operate the PMSM with less cogging torque. The proposed concept offers a significant decreasing in harmonics. Thus, the effect of VPI on the cogging torque can be understood. The inverter with a Field Oriented Control (FOC) method operates in 3-phase and 20 kHz switching frequency. The PMSM motor is fed by the inverter. The VPI based active damping control for the motor drive is discussed to confirm the performance of the proposed method. The simulation results based on MATLAB are provided to validate the proposed control strategy.
