WebA BHA with a straight motor and a bent sub above it is effective in a vertical or nearly vertical hole and is frequently used in a kickoff assembly. For hole inclination angles of 20° or more, the effectiveness of straight motors with bent subs is poor, and for this reason, downhole motors with bent housings (Fig. 8.39) were developed. WebApr 7, 2024 · The plotted motor current corresponds to the sum of the magnetizing current and mechanical friction associated with the rotating components of the drill rig, including gearbox and bottomhole assembly. The spectrum in Figure 7b shows that the motor current signal has a fundamental component around 47.9 Hz with an amplitude of 2.96 A. The ...

WebConventional induction motors, which dominate the downhole rotating equipment, achieve 85% efficiency with an approximately 1 mm air gap. PM machines achieve efficiencies over 90% with an approximately 13 mm air gap. This is due to the high magnetic field created by permanent magnets vs. energizing coils. This ability to operate with large ... WebPumps and motors are the components with the largest impact on energy consumed. Permanent magnet motors (PMMs) deliver higher efficiency, power factor, and power density as well as a wider range of operating speeds compared with conventional induction motors. REDA ESP pump PMM technology lowers electricity consumption by up to 10% … hopkins bakery tallahassee
