Product Description:
The MSK050C-0450-NN-S2-UG1-RNNN is a permanent-magnet servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is intended for precision axis control in industrial automation, where regulated torque and speed must track electronic drive commands within milliseconds. Typical duties include positioning of pick-and-place heads, coordinated motion in packaging machines, and following profiles in light machining centers. Its synchronous design supports responsive motion control when paired with a compatible drive and closed-loop feedback.
This model relies on natural convection to conduct heat away from the stator, so no auxiliary fan or coolant manifold is required. The housing complies with IP65, sealing the windings against dust and low-pressure water spray encountered on open production lines. Rated operation spans ambient temperatures of 0–40 °C, matching general plant conditions. An electrically released brake supplies 6 Nm of holding torque, automatically clamping the rotor whenever power is absent. Winding code 0450 identifies the motor's electrical winding configuration used with the paired IndraDrive amplifier. Insulation class 155 materials help the winding tolerate elevated temperatures during dynamic cycles.
Rotor position feedback is handled by an EnDat2.1 optical encoder that provides 2048 signal periods per revolution. The encoder is a single-turn type, delivering an absolute value for every shaft angle within one mechanical turn, while multi-turn counting is handled by the drive. Its hybrid power and feedback connector is rotatable 240°, so cable routing can be aligned with available installation space while maintaining strain relief. Increased concentricity machining minimizes radial runout on the plain shaft, which helps protect bearings during rapid acceleration and repeated positioning cycles. The C motor length and 050 frame size provide a compact envelope for machines that need servo performance in limited mounting space.
