BLDC motor conforms to environmental lab tests

BEI Kimco has announced the availability of a brushless DC (BLDC) motor for oil and gas exploration applications. The manufacturer’s claim that the DII15-60-201A motor can operate reliably under extremely harsh conditions is supported by two independent environmental test labs. BEI Kimco’s new high-pressure high-temperature (HPHT) motor has been certified by Precision Hermetic Technologies for temperature and pressure testing and by Intertek for shock and vibration testing. These lab tests validated the thermal, pressure, and vibration and shock load ratings of the motor throughout its operational life.

The testing validates that the DII15-60-201A motor can operate reliably under a continuous duty in temperatures of up to 205°C, atmospheric pressures of up to 30,000 psi, and shock and vibration loads approaching 1,000 g and 25 g, respectively.

The 1.5-inch-diameter motor is highly suitable for harsh down-hole applications such as mud pulser valves, caliper deployment, and sensor positioning. Walter Smith, applications engineer at BEI Kimco, says that the DII15-60-201A motor offers a solution that minimizes the downtime and high costs associated with motor failures.

The BLDC motor incorporates a proprietary Hall commutation circuit and structural enhancements coupled with advanced magnets to support high operating efficiencies and durability. The optional features include custom gearbox interfaces and alternate winding.
