Brushless DC motor used for oil exploration

BEI Kimco Magnetics designed a BLDC motor (brushless DC) for oil exploration.

08/16/2011


BEI Kimco Magnetics, a company of Custom Sensors + Technologies, Inc., recently met the challenging Brushless DC Motor requirements for a down hole oil exploration application.

Key to the product's design specification was a motor that would deliver 7.0 Nm (62 in-lb) of peak torque and 5Nm (44 in-lbs) at speeds of 2000 rpm on a continuous basis. The motor would also be required to survive ambient temperatures approaching 200 degrees and pressures of 30,000 psi. A final requirement was the need for Hall effect sensors for commutation.

BEI Kimco Model DII36-125-000A measures 3.6-in. outer diameter and 12.5-in. overall length. High energy samarium cobalt magnets were incorporated to ensure high efficiency operation, survive the extreme temperatures, and for improved corrosion resistance. A proprietary hall sensor support structure and advanced cable strain relief system were developed to achieve unprecedented reliability under the extreme conditions. The housing design allows the motor to be filled with oil to compensate for the high pressures, the company noted.

"Over the past few years BEI has developed a reputation for highly reliable motor solutions," said Walter Smith, BEI Kimco's senior applications engineer/project manager for motors.

BEI Kimco said it developed products for industrial, military, aerospace and medical applications.
