Systems and methods for real-time monitoring and control of well site operations employ well site edge analytics to detect abnormal operations. The systems and methods receive well site data from a remote programmable automation (PAC) controller at the well site, the well site data representing one or more operational parameters related to the well site operations. A probability is derived for a given slope for each one of the one or more operational parameters as correlated to a different one of the one or more operational parameters to produce correlated probabilities for the one or more operational parameters. A resultant probability is derived from the correlated probabilities for the one or more operational parameters and it is determined whether the resultant probability meets a preselected threshold probability value. A responsive action is initiated if the resultant probability fails to meet the preselected threshold probability value.

A motor includes: a first portion that includes a plurality of permanent magnets; and a second portion that includes a plurality of coils, wherein the first portion or the second portion is configured to be rotatable around a rotation axis, wherein the plurality of permanent magnets are circumferentially arranged about the rotation axis, and wherein the plurality of coils are arranged so as to face the plurality of permanent magnets in a direction along the rotation axis, and the motor further includes: a control unit that controls a rotational speed and an attitude of the rotating first portion or the rotating second portion by controlling currents that are applied to the plurality of coils.

A system comprises an electric submersible pump (ESP) motor electrically coupled to a variable speed drive (VSD) that outputs voltage to the ESP motor. The system comprises a magnet on a shaft of the ESP motor and a downhole sensor coupled to the magnet, wherein the downhole sensor is to measure a magnetic flux of the magnet. The system comprises a VSD controller to control the VSD, wherein the VSD controller comprises a processor and a non-transitory memory storage having instructions stored thereon that are executable by the processor to perform operations comprising: obtaining a measurement of at least one pump performance variable and a motor current for a first period of time to establish a first data set and making a first adjustment to a voltage output from the VSD to the ESP motor, the first adjustment having a first adjustment type.

Pumping and water distribution systems for pools/spas, and methods for control thereof are provided. A system includes a pump including a variable speed motor, a controller configured to control the speed of the motor, a plurality of pool/spa components, a plumbing subsystem placing the components in fluidic communication with the pump, and a plurality of control valves switchable between an open position and a closed position. Each of the control valves is associated with one of the components, positioned in the plumbing subsystem between the associated component and the pump to control the flow of fluid to the associated component, and is configured to provide a specific flow rate of fluid to the associated component based on a set system pressure when in the open position. The controller adjusts the speed of the motor to adjust the fluid pressure within the plumbing subsystem to match the set system pressure value.

An adhesive dispensing system for applying liquid adhesive to a substrate using different nozzles with the same manifold is disclosed. The adhesive dispensing system includes a manifold having a body, a first clamp configured to engage the body of the manifold, a second clamp configured to engage the body of the manifold, and a nozzle. The first and second clamps secure the nozzle to the body of the manifold. The body of the manifold has a first contact surface that engages the first clamp and a second contact surface that engages the second clamp and the nozzle, where the second contact surface is angularly offset from the first contact surface.

One or more sensors are mounted on a collar proximate to a motor shaft of a motor. The motor is associated with an electric submersible pump (ESP) located in a wellbore of a geological formation. The one or more sensors sense one or more identifiers located on the motor shaft of the motor. One or more of a rotation direction and rotation speed of the motor shaft is determined based on the sensing of the one or more identifiers. The motor is powered to pump fluid from a reservoir in the geological formation to a surface of the geological formation based on the one or more of the rotation direction and rotation speed of the motor shaft.
