ABB's BSM N-series provides applications with low inertia to attain the highest acceleration capability to allow you to position faster. The BSM N-series servo motors provide a rugged and durable design, with high energy Neodymium-Iron-Boron magnetics. This series provides continuous stall torque capability ranging from 3.9 Lb-In (0.45 N-m) to 354 Lb-In (40 N-m). Peak torque capability is nominally 4 times continuous. Features: Low inertia rotor design with Neo magnets - 5 standard frame sizes to choose Acceleration torques from 16 Lb-In (1.8 N-m) to 1400 Lb-In (160 N-m) High output torque at low speed - continuous 4 Lb-In (0.4 N-m) to 354 Lb-In (40 N-m) Inertia range .00006 - .034 Lb-In-s2 (.067 - 38 Kg-cm2) Standard windings for 160, 300, 650 bus volts- customs available Dependability designed in the high 155°C design Premium 200°C moisture resistant, multi-coated wire for reliability Extra high insulated stator for high voltage and current spike protection Superior bearings with Exxon PolyrexEM TM polyrex grease to provide 4 times greater life Rugged industrial construction to provide quality throughout the design Stock and customs available - IEC/NEMA designs UL/CSA/CE BSM Series Servo Motors Brochure
