January 31, 2010 - BEI Kimco Magnetics announced a motor for 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. 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.
