BEI Kimco Magnetics' HPHT brushless DC motor
DII15-60-200A is a 1.5-inch diameter, high-pressure, high-temperature (HPHT) brushless DC (BLDC) motor that provides the ideal solution for severe, downhole applications, such as mud-pulser valves, caliper deployment and sensor positioning. The motor has been successfully tested to operate under continuous duty in temperatures up to 205 ºC and pressures up to 30,000 psi. DII15-60-200A also features integral Hall commutation, and uses rare earth magnets to support high operating efficiencies and corrosion resistance. It's designed to withstand shock to 1,000 Gs and vibration to 25 Gs, and is built to endure the most extreme environmental conditions. DII15-60-200A also can be customized for gearbox or other feedback device options, and winding variations are offered to meet a wide range of controller voltages and currents.
