Abstract: Conventional axial flux motors typically include multiple rotors and stators resulting in a larger and heavier motor. Additionally, conventional axial flux motors include a housing to protect the rotors and stators, but the housing is often difficult to seal from the environment leading to risks of contaminants (e.g., dirt, water) infiltrating the motor and causing failure over time. The present invention overcomes these limitations by disclosing an axial flux motor with a single rotor and two stators. The use of a single rotor reduces the size and weight of the motor. An inboard housing and an outboard housing mechanically support the two stators and are joined together to define an interior cavity. A ring seal is disposed between the two housings to ensure the interior cavity is sealed. Additionally, the two stators may actuate multiple degrees of freedom (DOF) including the rotation of a wheel and actuation of a suspension.

Abstract: A method of assembling a tandem permanent magnet motor includes the steps of using an external visual reference system to align the stator assembly of the upper permanent magnet motor with the stator assembly of the lower permanent magnet motor. The external visual reference system includes a series of external reference marks that provide a mechanism for quickly aligning the upper and lower permanent magnet motors in the field prior to installation in a well as part of an electric submersible pumping system.

In one implementation, an ESP system includes an ESP, drive circuitry, a current sensor, a voltage sensor, and a processor. The ESP includes an electric motor. The drive circuitry is electrically coupled to the ESP and is configured to provide an electrical signal to power the ESP. The current sensor is configured to measure a current of the electrical signal. The voltage sensor is configured to measure a voltage of the electrical signal. The processor is configured to calculate speed of a shaft of the electric motor based on a frequency induced by rotation of the motor detected in the current. The processor is also configured to calculate a density of fluid in the ESP based on the speed.

Abstract: Various implementations include electric centrifugal pump assemblies for producing oil from wells. A submersible electric motor includes a housing, a shaft inside said housing that transmits rotational power from the electric motor section to the pump section, a mechanical seal surrounding the shaft to keep a dielectric fluid inside the electric motor, and a unit for compensating the volume of the dielectric fluid. Said unit maintains a constant positive pressure and includes a spring mounted inside a metal bellows. The spring is arranged in a tensioned state inside a cavity containing dielectric fluid. The spring is rigidly fastened facing the electric motor and to the bottom of the bellows such as to be capable of axial movement. The volume compensation unit is provided with a sensor for sensing the position of the spring/bellows. The cavity is filled with a barrier fluid preventing scale build-up.
