Magnetics Business & Technology - May/June 2022 - 20

FEATURE ARTICLE
...Continued from page 19. The following details are excerpted
from the company's descriptions which can be fully seen on its
website.
The accompanying diagram illustrates five key features of the
SCS:
1.
Active Magnetic Thrust Bearings - The active bearing
system supports hydraulic section thrust loads without any
physical contact or lubrication, delivering unlimited bearing life.
Magnetic bearing controllers located on the surface provide real
time information on thrust loads from the compressor to enable
system diagnostic and prognostic capabilities.
2.
Passive Magnetic Radial Bearings - The radial bearing
system supports high-speed rotating components radially
without any physical contact or lubrication, delivering unlimited
bearing life. Smart damping without the need of active controls
improves system stability by minimizing the vibrations of the
motors and compressors.
3.
Hermetically Sealed High Speed PM Motors - In
comparison to other types of motors used downhole, Upwing's
permanent magnet (PM) motors enable a shorter tool length
due to their higher energy density and lower heat dissipation
from higher efficiency levels. The completely canned motor system,
including both the rotor and stator components, isolates
the failure-prone electrical system from hostile downhole fluids.
4.
Hybrid Compressors - The hybrid multiphase compressor
system decreases the bottom hole flowing pressure
dynamically at the intake of the compressor and boosts the
pressure and velocity at the discharge to carry liquids uphole.
5.
Magnetic Coupling - Upwing's novel " protector-less "
design is enabled by transmitting the torque from the hermetically
sealed motor to the compressor without a mechanical
shaft.
PM Motor as Magnetic Coupling
The permanent magnet motor serves as a magnetic coupling.
In the MDS, the stator is canned as a part of the well's permanent
completion, allowing the rotor and other rotating pump
components to be retrieved independently from the stator.
There are no connections between the rotating and stationary
components. The stators initially are varnished with a vacuum
pressure impregnation process. All varnished copper wires are
potted, and the complete stator is inserted into a hermetically
sealed chamber for protection and reliability.
Lower Heat Dissipation
Magnetic losses are generated when magnetic field variations
cause losses in magnetically and electrically conductive materials.
The high strength magnets positioned on the rotor that
provide the magnetic field, rather than coils that need to be energized,
in a PM machine serve to minimize any field variations
to which the components on the rotor may be exposed.
Traditional ESP topologies, however, cannot take full advantage
of PM motor benefits by replacing an induction rotor with
a PM rotor, explains Upwing. The limiting factor of delivering
power in ESP applications is thermal management. In conventional
ESP motors, which operate in liquid filled chambers that
have a balanced pressure with the environment, the friction
losses generate more heat than the motor electromagnetic
losses. This heat must be removed from the motor and put into
the pumped fluid, where the only path is through the housing
