Product Description:

The MSK100C-0450-NN-M2-BP0-RNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This three-phase unit converts commanded current into controlled torque and speed, making it suitable for precision motion axes in packaging, material-handling, and metal-cutting machinery. It is delivered without a holding brake, so external means are needed for static load retention.

Heat produced by the stator is removed through natural convection, so installation must leave clearance around the frame rather than relying on forced fans. Position data are exchanged through the EnDat2.1 serial feedback channel; this bidirectional interface supplies absolute position, motor parameters, and diagnostics to the drive in a single cable. The optical encoder inside the housing resolves 2048 signal periods per mechanical turn, and because the scanning head is multiturn absolute it tracks rotations even during power loss. A sealed housing rated IP65 blocks dust and low-pressure water jets, enabling cabinet-free mounting on a machine frame. Class 155 insulation allows the windings to reach 155 °C without degradation, supporting continuous duty at high current density.

The electromagnetic package follows winding code 0450, giving torque constants matched to high-performance MSK controllers. Frame designation 100 and length C indicate the active iron stack, while the design with increased concentricity minimizes cogging for smoother velocity. Mechanical power is transmitted through a shaft with keyway, and the power cable exits on the B-side connector for straightforward routing in tight enclosures. The motor operates in ambient conditions from 0 to 40 °C. The motor has a length C housing, and the absence of active cooling components helps keep the assembly compact.
