Motor earns high marks in extreme validation testing

Immediate availability of validation test results has been announced for Sensata Technologies' enhanced BEI Kimco Brushless DC (BLDC) Motor DII15-60-201A in a completed validation test report. As substantiated by the testing, the motor can operate reliably under the harsh conditions of oil and gas exploration applications. The validation test report will be available to attendees at the upcoming Offshore Technology Conference, booth 4519, 1st-4th May 2017 at NRG Park in Houston, Texas, where the new motor will be showcased.

The extensive environmental test protocol for the enhanced BEI Kimco model DII15-60-201A High Pressure High Temperature (HPHT) BLDC motor was conducted and certified by two independent environmental test labs, Precision Hermetic Technologies for temperature and pressure testing, and Intertek for shock/vibration testing. These lab tests validated the thermal, pressure, vibration/shock load ratings of the motor throughout its operational life.

The Test Report describes test procedures, test data for each test sequence, certifications achieved, and documents the type of test equipment used throughout the process. The testing validates that the DII15-60-201A can operate reliably under continuous duty in temperatures up to 205°C, atmospheric pressures of up to 30,000psi and shocks/vibrational loads approaching 1,000g's/25g's respectively. The 1.5" diameter DII15-60-201A HPHT BLDC motor provides a useful solution for harsh down-hole applications such as mud pulser valves, caliper deployment and sensor positioning. The robust design also makes it suitable for other severe enviromental applications.

The DII15-60-201A incorporates a proprietary integral Hall commutation circuit, and structural enhancements coupled with advanced magnets to support high operating efficiencies and durability. Other variations include custom gearbox interfaces and alternate winding options.

"Upon review of the Validation Test Report, it is evident that the design has been subjected to the rigorous testing necessary to instill confidence that the motor can withstand the harsh conditions of oil and gas applications," said Walter Smith, Applications Engineer. "BEI Kimco's DII15-60-201A motor offers a solution that minimises the downtime and high costs associated with motor failures."
