The BSM N-series provides applications with low inertia to attain the highest acceleration
capability - to position faster - to obtain the highest machine throughput. Our motors are hard
at work, increasing productivity, improving part quality, providing precision and reducing cost
in many applications. This series provides continuous stall torques ranging from 3.9 lb-in (0.4
Nm) to 354 lb-in (40 Nm). Peak torques are four times continuous. This series has the lowest
inertia to provide the maximum torque per package size.
