MS2N03-B0BYN-CMSL0-NNNNN-NN

The MS2N03-B0BYN-CMSL0-NNNNN-NN is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MS2N Synchronous Servo Motors series. It serves as the rotary actuator in closed-loop drive systems where rapid acceleration, repeatable positioning, and electronic gearing are required on automated assembly lines, printing machinery, and material-handling axes.

This unit reaches a rated speed of 9000 1/min, allowing short cycle times when paired with a suitable inverter. Feedback precision comes from an Advanced – 20-Bit, ACURO®Link encoder, and absolute position tracking over 4,096 mechanical turns is provided by the multiturn feedback. The motor’s low inertia rotor minimizes torque demand during quick reversals, so the drive can follow high-frequency command profiles with less current. Mechanical construction follows B5 / IM3001 with integrated PT1000 sensing for winding temperature supervision, while frame length B matches the MS2N03 size code listed in the type designation. A standard bearing arrangement, standard flange exactness, and general-purpose design features keep the mechanical interface consistent across the series. Standard varnish in RAL 9005 black protects the laminated core and housing surfaces from moisture and contaminants.

Thermal management relies on self-cooling; heat is dissipated through the housing without forced airflow, simplifying cabinet layouts. Power and encoder conductors exit through a single cable connection M23, rotatable, which eases routing in tight installations. For applications that hold position by drive torque alone, the motor is supplied without a holding brake. The shaft is machined with a keyway, without a shaft sealing ring, so users must install an external seal if oil migration is expected. A standard varnish, RAL 9005 black finish completes the assembly, providing uniform appearance and basic corrosion resistance while keeping overall weight low.
