Product Description:

The MSK040C-0450-NN-M1-UP1-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop positioning and velocity control, the motor couples directly to precision gear stages or machinery shafts and returns real-time feedback to compatible drive controllers. Its compact 040 frame size and C-length housing allow installation in space-restricted automation zones, while the standard design supports general-purpose mounting arrangements in packaging lines, pick-and-place modules, and small handling axes.

This model dissipates heat through natural convection, so no external blower or liquid circuit is required. Rotor position is reported through the Hiperface protocol, which carries commutation data and diagnostic information over a digital serial interface. The integrated encoder provides 128 signal periods per mechanical revolution, helping the drive maintain stable position and speed control. The feedback system uses optical scanning technology for low interpolation error and stable signal quality. For motion hold during idle or power-off states, an electrically released brake supplies 4 Nm of static torque, helping prevent drift on vertical loads or tensioned conveyor axes.

The motor’s feedback connector can be oriented through 240°, which helps route cables around nearby machine structures without forcing tight bends. It uses a Multiturn Absolute encoder structure, so absolute position values remain available across multiple shaft revolutions without requiring a reference move after every restart. Mechanical output is delivered through a shaft with a keyway, which supports positive torque transfer with standard keyed couplings. The motor uses winding code 0450, which matches the electrical characteristics expected by compatible IndraDrive compact inverters.
