MSK101E-0300-NN-M1-RG2-NNNN

The MSK101E-0300-NN-M1-RG2-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated production cells it delivers commanded velocity and torque directly to linear stages, rotary tables, and tooling spindles, enabling closed-loop motion sequences with repeatable positioning accuracy.

The motor is rated with Cooling FN, meaning the housing must shed heat through ambient airflow; it therefore uses Natural convection rather than forced ventilation. Inside the end-bell an encoder using the Hiperface protocol transmits position and diagnostic data over two differential channels. Its photodiode array resolves each mechanical revolution into 128 signal periods, and the Optical sensing method keeps interpolation free from magnetic hysteresis. Because the scanning unit is a Multiturn Absolute model, up to 4,096 shaft turns are counted and stored without battery backup, so the drive immediately knows machine position after power restoration. Physical parameters include motor size 101 and length code E, giving a stator stack suited to medium inertia loads while keeping the overall footprint under 290 mm. The construction follows a standard design that matches the rest of the series for mounting and sealing requirements.

Process stability during emergency stops is maintained by the electrically released brake that exerts 70 Nm of holding torque when power is removed. Connections for power and protective earth leave the frame on the Right-side, simplifying daisy-chain wiring in multi-axis gantries. A cylindrical Plain shaft with center tap accepts clamp couplings or shrink-fit hubs without keyways. The electromagnetic constants defined by winding code 0300 match drive controllers that supply moderate continuous current with high short-term overload, supporting dynamic indexing and dwell cycles while the natural-convection housing keeps thermal rise within design limits.
