Product Description:
The MSK071E-0450-NN-S1-UG1-NNNN synchronous servomotor is manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It is intended for precision velocity and position control in automated assembly lines, material-handling gantries, and similar closed-loop motion axes where high dynamic stiffness and compact dimensions are required. By supplying torque directly to a coupled load, it reduces transmission backlash and lets the drive follow programmed trajectories with minimal position error. Its compact form factor also helps it fit machine sections where moving mass and mounting space must both remain limited.
The motor relies on natural convection to remove winding heat, so installation clearance around the housing is necessary, but external blowers or liquid circuits are not. Its mechanical build uses a plain shaft for backlash-free clamp or collet couplings, and a rotatable 240° encoder connector eases cable routing in tight cabinets. Feedback is transferred over the Hiperface interface, and the integrated single-turn encoder generates 128 signal periods per revolution using an optical scanning method to supply the drive with position data. An electrically released holding brake is fitted and can exert 23 Nm of static torque to maintain axis position whenever the servo amplifier is disabled. Frame size 071 and length code E set the electromagnetic stack for the selected footprint.
The enclosure has an IP65 protection rating that helps keep dust and low-pressure water jets away from internal components. Reliable operation is specified for ambient temperatures from 0–40 °C, keeping internal losses within the insulation system's class 155 thermal limit. The winding code 0450 indicates the electrical characteristics used by compatible IndraDrive controllers. The sealed enclosure suits indoor industrial areas where dust or occasional washdown splash may be present. Heat is removed through the housing, so airflow around the exterior should remain unobstructed during operation, and that arrangement avoids separate hoses or fan assemblies around the axis.
