BEI Kimco Magnetics (www.beikimco.com), a subsidiary of Custom Sensors & Technologies (CST), Inc., has met the demanding Brushless DC Motor requirements employed in a Down Hole Oil Exploration application.
The product’s design should feature a motor that delivers 62 in lbs (7.0 Nm) of peak torque and 44 in lbs (five Nm) at 2000 rpm on a continuous basis, while surviving pressures of 30,000 PSI and ambient temperatures around 200 degrees. The product should also feature Hall effect sensors for commutation.
BEI Kimco’s Model DII36-125-000A, which comes with a motor measuring 12.5 inches in overall length and 3.6 inches in diameter, met these requirements for a robust and highly reliable design. DII36-125-000A’s high energy samarium cobalt magnets allowed it to ensure high efficiency operations, offer improved corrosion resistance while surviving extreme temperatures. Its advanced cable strain relief system and proprietary hall sensor support structure helped it achieve exceptional reliability under extreme conditions. Meanwhile, the product’s housing design compensated high pressures by allowing the motor to be filled with oil.
“Over the past few years BEI has developed a reputation for highly reliable motor solutions,” said Walter Smith, Senior Applications Engineer/Project Manager for Motors at BEI Kimco.
“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.”
