Product Description:

The MSK040C-0450-NN-S1-UG0-NNC1 is an IndraDyn S synchronous servo motor built by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. As a compact rotary actuator, the unit converts drive controller current into the shaft torque and speed needed for positioning tables, packaging feeders, and other automation axes. When connected to a compatible drive, it supports closed-loop motion tasks that require repeatable starts, stops, and speed changes. Its compact format makes it suitable for installations where responsive motion and a small motor envelope are both important.

With a frame size of 040, the motor uses a stator diameter and mounting pitch suited to light-duty axes, while the C length code provides a medium active stack that balances torque density and inertia. Heat produced by the winding set is removed by natural convection, so the enclosure surface must remain unobstructed during operation. The housing has an IP65 protection rating, sealing internal components against dust and low-pressure water jets. The motor uses insulation class 155, and it is intended for ambient temperatures from 0 to 40 °C without auxiliary cooling. Because cooling is passive, the motor can be installed without separate fan hardware, which helps keep the surrounding machine layout simple.

The servo’s plain shaft transmits motion directly to couplings, and the lack of a holding brake reduces axial length where static clamping is handled elsewhere. A rotatable 240° connector simplifies cable routing inside tight cabinets and links the optical encoder to the drive. Position data are exchanged over the Hiperface protocol, and the sensor provides 128 signal periods per revolution with single-turn tracking for commutation and stable velocity control. The feedback arrangement lets the drive monitor rotor position accurately during acceleration, steady running, and low-speed movement. Cable orientation can be adjusted to reduce strain where the motor is mounted close to guards or machine frames. Winding code 0450 matches the electromagnetic layout to applications such as medium-speed indexing and synchronized print rollers.
