Product Description:
The MSK076C-0450-NN-S3-UP1-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied in the MSK IndraDyn S Synchronous Motors series. The unit converts drive-controller current into precise rotary motion for positioning, indexing, and continuous-duty axes in automated machinery. It is intended for closed-loop operation with a compatible drive and feedback system, where accurate speed regulation and repeatable positioning are required. Its compact 076 frame and C length create a torque-dense package that fits tightly spaced cabinets and gantry carriages while maintaining inertia ratios suited to modern motion loops.
Thermal behavior is managed by natural convection, so the motor can be mounted without forced airflow and still maintain the continuous-duty performance associated with winding code 0450. A rotatable 240° encoder connector simplifies cable routing where space around the motor is limited. The integrated capacitive encoder uses the Hiperface interface with 16 signal periods of single-turn resolution to send absolute position data directly to the drive. The motor also has an IP65 enclosure that seals the stator against dust and water jets encountered on production floors.
Machine safety is supported by a spring-applied, electrically released brake that delivers 11 Nm of holding torque, allowing vertical or load-holding axes to remain motionless when power is removed. A shaft with keyway supports positive mechanical locking for pulleys or gearboxes. The motor operates in ambient temperatures from 0–40 °C, which supports use in standard industrial environments. Its insulation system is rated to class 155 for the winding temperatures reached under cyclic loading. This helps protect the windings during repeated acceleration and deceleration cycles.
