REDA Maximus Eon

Extended-life, install-ready ESP motor

Maximus Eon motor improves ESP reliability with cooler running temperatures as compared with previous-generation ESP motors.

Wide-ranging impact

Hundreds of thousands of ESPs currently operate in diverse industries, and most of them use induction motor technology. REDA Maximus Eon extended-life, install-ready ESP motor’s optimized electromagnetic design delivers a minimum of 3.5% higher electrical power efficiency—directly reducing energy consumption and Scope 1 or Scope 2 emissions, with applicability across a range of industrial sectors.

Increase ESP reliability and lifetime with a cooler, more robust, and more efficient motor

REDA Maximus Eon extended-life, install-ready ESP motor delivers industry-leading efficiency and power factor with optimized motor geometry for maximum electromagnetic and thermal performance through the operating range.

The two-pole, three-phase, squirrel-cage induction motor transfers generated heat to the well fluid flowing past the motor housing, and the motor thrust bearing carries the load of the rotors.

REDA Maximus Eon Motor: Introduction
Find out how your wells can benefit from a cooler, more robust high-efficiency ESP motor.

Improve motor performance and flexibility

The motor can be delivered with standard thermally optimized windings or encapsulated windings for extra cooling that lower operating temperature by as much as 30 degF [16.8 degC]. A temperature-sensing device enables real-time monitoring of motor-winding temperature.

Simplify installation and enable real-time monitoring

The motors are factory vacuum filled in a controlled environment with high-temperature synthetic oil to provide dielectric strength, lubrication for bearings, and thermal conductivity. MaxJoint ESP flange connection and MaxLok ESP quick-plug motor lead extension (MLE) simplify installation at the wellsite. The gauge-ready base is also compatible with any Phoenix artificial lift downhole monitoring systems sensor for real-time monitoring of ESP and reservoir properties.

The new electromagnetic-optimized geometry enables boosting horsepower by 33% compared with prior-generation motors.

† The performance improvement is based upon a 540-hp motor configuration and in comparison with previous-generation induction motor technology. Calculations are based on a run life of 365 days with 100% uptime and take into consideration efficiency losses of the power cable, variable frequency or variable speed ESP drive, and transformer. The conversion from electricity to CO2 is based on the IEA (2019) Emission Factors reference of 485.30 g of CO2/kW.h.

‡ The potential CO2 savings per year per well are equivalent to eliminating emissions from 216,135 miles [347,835 km] driven by an average passenger vehicle, as determined using the Environmental Protection Agency’s greenhouse gas equivalencies calculator.
