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

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
