Brushless DC HPHT motor rugged enough for oil drilling

May 5, 2015 By Lisa Eitel Leave a Comment

BEI-Kimco-BLDC-for-drilling-motorBEI Kimco Magnetics now sells a rugged brushless DC (BLDC) motor to withstand harsh oil-exploration applications … as well as other severe-environment applications that can’t have failures.

Called the DII15-60-200A High Pressure High Temperature (HPHT) brushless dc motor, it’s tested to operate under continuous duty in temperatures up to 205º C and pressures to 30,000 psi.

As oil extraction reaches greater depths, drilling equipment must withstand increasing temperatures and pressures under extreme shock and vibration. One hour of downtime can cost $100,000, and replacing a motor in drilling applications can take up to ten hours or more.

So, durable HPHT motors are essential.

The new 1.5-in. diameter DII15-60-200A motor works in down-hole applications such as mud pulser valves, caliper deployment and sensor positioning.

“We’ve subjected the design to an extensive environmental test protocol at 30 kpsi. This qualification test data proves motor performance in these deep drilling conditions where temperature, pressure, shock and vibration extremes combine to create a destructive environment for equipment operation,” said Walter Smith, BEI Kimco applications engineer and project manager.

The manufacturer took a decades-old design and pushed the performance envelope into the HPHT realm. The resulting motor features integral Hall commutation and uses rare-earth Magnets to support high operating efficiencies and corrosion resistance. Designed to withstand shock to 1000 g and vibration to 25 g, the new BLDC motor endures extreme environmental conditions. Some DII15-60-200As sport custom gearboxes and feedback. Winding variations help OEMs meet a myriad controller voltages and currents.

“Today oil and gas operators have been forced to simply endure high motor failure rates, ultimately resulting in hours of downtime and hundreds of thousands of dollars lost,” added Smith.
