Product Description:

Bosch Rexroth Indramat’s MSK100B-0300-NN-M2-RG0-RNNN belongs to the MSK IndraDyn S Synchronous Motors series and serves as a synchronous servo motor for high-precision positioning and velocity control on automated axes. Its electromagnetic design and mechanical form factor let it operate as an integral drive element in packaging machinery, printing lines, and material-handling gantries. The digital feedback chain supports tight motion loops and repeatable accuracy during continuous operation. This arrangement suits machines that require precise speed regulation as well as accurate position control during repetitive cycles.

The integrated feedback system combines a multi-turn absolute encoder, the EnDat2.1 serial interface, and optical scanning to supply real-time position data. Resolution reaches 2048 signal periods per revolution, supporting fine interpolation in the drive controller. This feedback arrangement supports stable commutation and position monitoring across varying operating speeds. Winding code 0300 indicates the stator resistance, inductance, and thermal load characteristics, helping the motor maintain constant torque when operated at rated current. The motor uses a plain shaft for direct coupling to gearboxes or couplings without keyways, which helps reduce torsional backlash. It is supplied without a holding brake, so load-side static retention must be provided by external mechanics or drive torque, and power and feedback connections are routed through a single housing.

Thermal management relies on natural convection, so heat leaves the frame through its surface without auxiliary fans or liquid circuits. The rotor and stator use increased concentricity to reduce radial runout and support smooth velocity profiles at higher speeds. Frame size 100 sets the mounting pitch and flange diameter used for this portion of the series. A power connector on the right side places the cable exit for installations that favor lateral routing and clear adjacent machine structures. Motor length code B adds axial depth for additional copper while keeping overall mass within common handling limits, and the larger axial length increases active material while preserving the basic frame geometry.
