Product Description:

The MSK071D-0450-FN-S2-UP2-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. The unit converts controlled electrical power into precise rotary motion for positioning axes and continuous-duty drives in industrial automation cells. As an IndraDyn S motor, it integrates feedback electronics and mechanical features needed for closed-loop drive systems on packaging lines, machine tools, and robotic handling stations. Its synchronous design supports accurate torque production and stable speed control during indexing, contouring, and continuous-motion tasks. This allows the motor to serve demanding axes that must respond quickly to changing load and motion commands.

The motor relies on liquid cooling, designated as cooling mode FN; circulating coolant removes stator heat so the drive can sustain peak torque without derating. A rotatable 240° hybrid connector supports flexible alignment of power and feedback cabling without twisting conductors. Position data is reported through the EnDat2.1 serial interface, and the optical encoder delivers 2048 signal periods per revolution; this resolution supports fine velocity control in high-speed axes. Because the encoder is configured as a single-turn device, absolute position within one mechanical rotation is available after power-up. An electrically released holding brake supplies 30 Nm of static torque for load retention during standby, and the housing carries an IP65 rating that blocks dust ingress and water jets in production environments.

The motor uses insulation class 155, which permits winding temperatures up to that class index before insulation life is reduced. The rated operating range is 0 to 40 °C, so continuous duty is possible in most factory environments without auxiliary conditioning. Power is transmitted through a shaft with a keyway, giving positive mechanical locking to pulleys or couplings while preserving concentricity for the D-length 071 frame.
