BEI Kimco Magnetics' BLDC Motor Solves Challenging Application Requirements for 2.0 HP 200 Degree Celsius Capabilities



VISTA, Calif. − BEI Kimco Magnetics, a company of Custom Sensors & Technologies (CST), Inc., recently met the challenging Brushless DC Motor requirements utilized in a Down Hole Oil Exploration application.

Key to the product's design specification was a motor that would deliver 7.0Nm (62 in-lbs) 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.

To meet these demanding requirements for a highly reliable and robust design, BEI Kimco designed their Model DII36-125-000A. The resulting motor 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.

"Over the past few years BEI has developed a reputation for highly reliable motor solutions," says Walter Smith, BEI Kimco's Senior Applications Engineer/Project Manager for Motors. "We are constantly designing products to meet the unique needs of each individual application. Our customers have come to rely on this expertise in a wide range of industries."

BEI Kimco products have been used successfully in countless applications from high-end Industrial to Military and Aerospace to Medical applications. The ability to provide high performance solutions tailored to the specific needs of the customer has allowed BEI Kimco to fulfill many challenging requirements.
