Brushless Motors Meet Centrifuge

Oct. 28, 2016
For reliable, quiet operation

Brushless DC (BLDC) motors DIT11-15 and DIH40-49 meet the necessary specifications of the individual centrifuges including operating speeds approaching 25,000 RPM.


While the DIT11-15 motor delivers relatively moderate torque levels of 3.0 oz-in given its small size (1.1" in diameter x 1.28" in axial length), it does incorporate integral drive electronics for a more simplified external control scheme. In contrast, the robust DIH40-49 design is capable of power levels approaching 500 watts in a size of 4.0" in diameter x 4.9" in axial length.


These two brushless motors provide impressive low noise characteristics that are achieved through precision rotor system design methodologies and bearing selection.
