Product Description:

The MSK071D-0450-FN-M2-UG0-RNNN is a synchronous servo motor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It uses an IndraDyn rotor-stator platform to provide torque and position control for automated axes such as pick-and-place stations, packaging machines, and gantry drives. This arrangement supports precise motion in systems that require repeatable acceleration, steady speed control, and accurate positioning under changing loads. Its size 071 stator and D-length housing keep the frame in a mid-range format, and the plain output shaft allows direct coupling to gearboxes or loads without the imbalance associated with a keyway.

This motor relies on liquid cooling that circulates through an internal jacket to remove heat directly at the stator, so the flange temperature remains stable during continuous high-current operation. Because heat is removed at the stator jacket, the motor can sustain demanding duty cycles without relying on external airflow around the housing. Feedback is managed by a modular encoder system whose connector can rotate through 240°, simplifying cable routing in tight cabinets. Position data are transmitted over the EnDat2.1 serial interface, which supports automatic parameter transfer to the drive controller. The measuring element uses optical scanning and generates 2048 signal periods, providing fine incremental resolution before interpolation. The 0450 winding code matches the motor to standard IndraDrive inverters for consistent torque production.

The encoder provides multiturn absolute position data, so the axis power-on position is available without homing even after mechanical rotations that exceed 360°. The motor is supplied without a holding brake, which lowers inertial load and suits applications that use external clamping or vertical counterbalances. That combination is useful on axes where retaining force is handled elsewhere and where restart position must be known immediately after power is restored. The housing has an IP65 rating that protects the windings against dust ingress and water jets when the mating connectors are installed. Thermal insulation class 155 supports continuous winding temperatures within the stated 0 to 40 °C ambient range when the specified liquid flow is maintained.
