Product Description:

The MSK071C-0450-NN-M2-UP1-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It provides closed-loop rotary motion for automated assembly lines, processing machines, and gantry axes where accurate positioning and repeatable dynamics are required. Integrated feedback, a sealed housing, and an electrically released brake combine the mechanical, electrical, and holding functions needed for direct coupling to a drive controller. This configuration is suitable for axes that must maintain controlled motion during operation and secure holding at standstill.

The motor dissipates heat through natural convection, so no fan or coolant lines complicate installation. An IP65 enclosure keeps airborne dust and washdown spray away from the stator and encoder elements, permitting mounting near production areas. Position data travels over the EnDat2.1 serial link, and the optical measuring system yields 2048 signal periods per revolution, giving the control loop fine resolution for velocity and phase alignment. During power loss or emergency stop events, an electrically released brake provides 23 Nm of holding torque, securing the load without additional clamping hardware.

The encoder stores absolute position across multiple turns, and the multiturn absolute design removes the need for homing after startup. A rotatable, 240° plug allows the feedback cable to exit in the most practical direction when installation space is limited. The motor uses a keyed shaft for torque transmission, and increased concentricity machining helps reduce radial runout. Continuous duty is allowed in ambient temperatures from 0–40 °C, and insulation class 155 protects the windings against normal thermal stress. Frame size 071 with length code C and winding code 0450 places the unit in a compact configuration for machines that need stable servo response.
