Product Description:

The MSK100B-0300-NN-M2-BG1-RNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It delivers controlled torque and speed to industrial positioning and processing axes, supporting precise closed-loop motion in packaging, printing, and material-handling machines. Its synchronous design allows the paired drive to maintain accurate motion during indexing and speed-controlled operation.

This unit relies on natural convection for heat dissipation, so airflow around the housing must be maintained. The rotor-stator assembly is machined for increased concentricity, which helps reduce radial runout during rotation. Position feedback is generated by an optical encoder that communicates through the EnDat 2.1 digital interface, and bidirectional data include position, diagnostics, and stored motor data. The encoder produces 2048 signal periods per mechanical revolution, and its multi-turn absolute design preserves position after a power loss. A spring-applied, electrically released brake supplies 32 Nm of static holding torque to keep the load at rest when the drive is disabled. The motor has an IP65 enclosure rating that blocks dust ingress and water jets. Thermal insulation is Class 155 for continuous winding temperatures up to 155 °C.

Mechanical connection is via a plain shaft, which simplifies coupling where backlash must be minimized. The motor operates in ambient temperatures from 0 to 40 °C without derating. Frame size 100 and length designation B correspond to the active iron length, giving a balanced inertia-to-torque ratio for medium-power axes. Winding code 0300 identifies the stator coil set used with the matching IndraDrive amplifier. Power is routed through the B-side connector to keep cabling clear of the encoder flange and support orderly cable routing.
