Baldor AC Servo Motor BSM N-Series

Baldor'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 issued in the world's fastest machines and demanding applications.

The N-series brushless servo motors provide a very responsive acceleration in a rugged, 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. This series has the lowest inertia to provide the maximum torque per package size.

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)
