Our customers' challenges evolve and so do our products. The R&D department strengthened and expanded the Nar Motion products series accordingly. A series of motor controllers dedicated to the oil & gas applications.

To each use, a dedicated product

The Nar Motion series includes five motor controllers to meet any customer need for downhole tools: Nar Motion XS, Nar Motion S 60V, Nar Motion S 250V, Nar Motion M and Nar Motion L. Failure is not an option. To make the most of the well, each Nar Motion got designed to serve its purpose with several form factors, several configurations, and optimal efficiency.

The features and complexity differ on the task that the motor will be performing. With an average rate of 98% efficiency, Watt & Well's motor controllers are the top-of-mind products on the market.  The ruggedized designs generate less heat, less noise, and fewer motor vibrations while producing more performance.

Nar Motion Series

The advanced solution for severe environments

The Nar motion series is built on the combined and proud heritage of the harsh environments know-how and power electronics expertise. Over ten years of experience and hundreds of motor controller equipment currently running thousands of feet below ground, make us confident in the reliability of our products.

So, prior to the design, the engineers dig the concept of high-reliability to withstand:

  • Extreme temperature from -40°C/°F to 175°C/347°F with a maximum survival temperature up to 200 °C/392 °F
  • Random vibration up to 20G rms, 50-500Hz
  • Repetitive shocks (up to 500 G)


Maximizing results at best cost

We understand both the stakes and constraints of our customers. Any delay in commissioning results in financial and reputation expenses. As a result, Watt & Well is committed to delivering optimal operational motor controllers.

The Nar Motion series is tested with the Accelerated stress techniques such as HALT (Highly Accelerated Life Test) and HAST (Highly Accelerated Stress Test). It is based on a series of thermal and mechanical tests aimed at detecting defects and weaknesses in the electrical equipment.

Watt & Well has a library of tested and approved components because when operating thousands of feet below ground the last thing a service provider wants is to have its drill stop because of a component failure. The Nar Motion series provides sharp optimal operation into severe environments, because at Watt & Well we convert power into confidence.
