Brushless motor gives oxygen therapy the silent treatment
Engineering360 News Desk | July 27, 2021For patients reliant on oxygen therapy for a severe lung disease, oxygen concentrators offer more mobility than heavy, bulky oxygen tanks. But patients say even smaller devices weighing as little as 5 lb and measuring less than 12 inches wide and tall can be noisy and tiring to carry. To hurdle these challenges, Moog Industrial Controls segment, a division of Moog Inc., offers designers and makers of medical equipment the Silencer BN series brushless DC motors for oxygen concentrators.
The smallest Silencer motor, including housing, measures 1.2 inches in diameter and 1.3 inches long. The Silencer series motors have a continuous torque ranging from 2.4 to 519 ounces per inch, speeds up to 20,000 rpm and range-rated power up to 874 W.
A high level of efficiency also ensures a longer battery operating life for oxygen concentrators, whether running in a pulse-flow or continuous mode. Moog also designed the Silencer with high-energy magnets and exceptional winding density to not only reduce the motor’s size but also generate nearly twice as much torque as conventional stator technology.
