Product Description:

The MSK101C-0450-FN-M1-BG2-NNNN servo motor is built by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. In automated machinery, this motor serves as the rotary actuator that turns drive current from an IndraDrive controller into tightly regulated shaft motion, giving position and speed control for indexing tables, feeders, and coordinated multi-axis systems. When paired with a compatible drive, it supports closed-loop motion on packaging, material-handling, and general automation equipment. It is intended for dynamic servo applications that require accurate acceleration, repeatable positioning, and stable speed regulation during changing load conditions.

An FN identifier in the type code indicates that the unit uses liquid cooling; the internal coolant channel removes heat directly from the stator so continuous torque is not limited by ambient air. Position feedback is generated by an optical encoder that transmits through the Hiperface interface; its scan head reads 128 signal periods per mechanical revolution and stores position data with multiturn absolute tracking, eliminating homing cycles after power loss. An electrically released brake rated at 70 Nm holds the load whenever the drive is disabled, which is useful on vertical or suspended axes. The housing meets a protection level of IP65, blocking dust ingress and water jets so the motor can be mounted outside a sealed cabinet. Power wiring enters through the B-side connector, which can simplify cable routing on machines with fixed cable paths.

The mechanical interface uses a plain shaft, which mates with shrink discs or clamp couplings to transfer torque without backlash. Thermal integrity is supported by Class 155 insulation, allowing winding temperatures up to 155 °C when the liquid circuit keeps stator copper within limits. Reliable service is specified for ambient temperatures of 0–40 °C, matching most control-room and factory environments. Additional identification details include length code C, frame size 101, and winding code 0450. These codes distinguish the mechanical length and winding arrangement used for this motor version.
