Product Description:

The MSK076C-0450-NN-S1-UP1-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It provides closed-loop rotary motion for positioning and speed control in automated machinery, where accurate feedback and steady torque response are important. When paired with a compatible drive, the motor can react quickly to changing load conditions while maintaining commanded motion. The unit uses motor size 076 with length class C and a standard design, so the housing, mounting dimensions, and insulation system follow the normal configuration used across the series.

This model is cooled by natural convection, so no external blower or liquid circuit is required. That approach keeps the motor self-contained and avoids separate cooling lines or fan assemblies around the machine. The feedback system uses Hiperface communication and an optical scale with 128 signal periods per revolution, which supports commutation and precise position interpolation. A rotatable 240° encoder connector allows the plug to be set over a wide angular range, making cable routing easier in tight enclosures. This feedback layout supports stable signal transmission between the motor and the drive while keeping installation flexible.

Inside the encoder, optical sensing is paired with single-turn operation, so the motor reports absolute position within one mechanical revolution. An electrically released holding brake provides 11 Nm of static torque to hold vertical or inertial loads when power is removed. The output uses a shaft with keyway, which transfers torque through a keyed hub instead of a friction-only connection. This arrangement is suited to driven elements that require positive torque transmission during repeated starts and stops. Winding code 0450 indicates the coil arrangement and related electrical values expected by the drive, helping the controller apply appropriate current and thermal parameters.
