Product Description:
The MSK050C-0450-NN-M3-UP1-NNNN is an IndraDyn S synchronous servomotor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It converts drive current into controlled torque and speed for positioning, contouring, and indexing axes on packaging equipment, handling robots, and machine tools that rely on closed-loop motion control. Direct shaft coupling can eliminate belt reduction, which helps reduce backlash while the compact frame supports high-acceleration duty cycles on modern production lines. When paired with a compatible servo drive, the motor supports precise starts, stops, and repeatable path control under changing loads.
The motor rejects heat through natural convection, a passive cooling method that avoids external fans and simplifies surrounding airflow requirements. Its electrically released holding brake supplies 6 Nm of static torque, allowing vertical axes to remain stationary when power is removed. This brake is intended to hold a stopped axis rather than replace dynamic braking by the drive. A housing rating of IP65 seals the stator against dust ingress and low-pressure water jets in washdown areas. Feedback signals travel over the Hiperface protocol, and rotor position is measured by a capacitive sensor head that delivers 16 signal periods of internal resolution; the connector can be rotated 240° to ease cable routing. Continuous operation is permitted in ambient rooms between 0–40 °C under natural cooling conditions.
The frame size is 050, and length code C provides a longer active section within this housing. Winding code 0450 sets the electrical values expected by compatible IndraDrive amplifiers during operation. Thermal endurance follows insulation class 155, supporting continuous winding temperatures near the design limit without accelerated aging. The motor has a keyed shaft for positive torque transfer to pulleys or rigid hubs, and the standard housing uses the common mechanical interfaces found across the MSK family. Its multiturn absolute feedback retains position information after power is restored.
