High Temperature Down Hole Drilling (MWD/LWD)
VISTA, Calif., – January 28, 2010–BEI Kimco Magnetics, a company of Custom Sensors & Technologies
(CST), Inc., recently met the challenging high-performance motor requirements for a Down Hole
Measurement While Drilling (MWD) application. With oil companies drilling deeper than ever before to
obtain increasingly valuable deposits, components within the drill tool must deliver reliable operation at the
most extreme ambient temperatures.
Key to the down hole tool string design was a motor capable of extended operation at elevated winding
temperatures of up to 220 °C and pressures approaching 30,000 PSI. The motor would be used to position
a sensor that would take measurements of the materials encountered during the oil exploration operations.
To meet the manufacturer’s requirements, BEI Kimco developed a High Performance Motor measuring 3.0”
in diameter x 8.5” in length with a custom housing and dual shafts for gearbox and resolver mounting. High
energy samarium-cobalt magnets were utilized to provide high operating efficiencies and superior corrosion
resistance. The motor was also designed for operation while filled with oil to compensate for the high
pressures. These tailor-made features combined to provide a highly robust solution.

Application for High Temperature
Down Hole Drilling (MWD/LWD)
“Performing drilling and logging operations at ever increasing depths is extremely expensive and our
customers cannot tolerate failure of any of the components within the tool string,” says Walter Smith, BEI
Kimco’s Senior Applications Engineer/Project Manager for Motors. “If the motor failed to position the
sensor properly, the accuracy of the measurement would be compromised and the tool would have to be
pulled up. Time is money, so reliability at these severe temperatures was paramount to the motor’s
design.”
BEI Kimco’s motors and actuators with extended temperature operation range capabilities have been used
successfully in countless mission-critical applications for many high-end industrial and military applications.
The ability to provide high-performance solutions tailored to the specific needs of the customer has allowed
Kimco to consistently fulfill unique and challenging OEM requirements.
We will be happy to discuss your application for our motion control products as well.
