High Pressure High Temperature Downhole Brushless DC (BLDC) Motors

  • Rated up to 205°C and 30,000 PSI with integral Hall commutation
  • Capable of withstanding shock loads in excess of 1000g
  • Vibration resistance of 25g RMS
  • Proprietary structural adhesive and insulation material increases reliability under continuous duty operation
  • Tested for operational life in excess of 600 Hours

BEI Kimco’s High Pressure High Temperature (HPHT) Brushless DC motor is designed for the most extreme ambient temperature and pressure environments. The Hall commutated design has been validated under the most extensive environmental test protocol in the industry to ensure survivability at ambient operating temperatures of up to 205°C, atmospheric pressures levels of 30,000 PSI and the high shock and vibrational loads present in the most extreme MWD and LWD applications. This proprietary design is highly customizable and is available in a wide range of torques and speeds, as well as configured for gearboxes or other feedback devices.
