Brushless DC Motor

BEI Kimco Magnetics (Vista, CA) introduced the DII15-60-200A High Pressure High Temperature (HPHT) brushless DC (BLDC) motor developed specifically to withstand harsh conditions found in the oil exploration Industry. The robust design also makes it suitable for other applications found in severe environments. The 1.5" diameter motor provides a solution for severe down-hole applications such as mud pulser valves, caliper deployment, and sensor positioning. The motor operates under continuous duty in temperatures up to 205 ºC and pressures up to 30,000 psi.

The motor features integral Hall commutation and uses Rare Earth Magnets. Designed to withstand shock to 1000g’s and vibration to 25g’s, the motor can be customized for gearbox or other feedback device options. Winding variations are offered to meet a wide range of controller voltages and currents.
