Product Description:
The MSK040B-0450-NN-M1-UP1-NNNN is an IndraDyn S synchronous servomotor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It is designed to deliver controlled torque and accurate position response for axes in automated assembly lines, packaging equipment, and pick-and-place gantries. In these systems, the motor works with a compatible drive to support repeatable starts, stops, and directional changes during short-cycle motion. Its compact format suits installations that need precise servo response, reliable feedback, and stable operation in space-limited machine sections.
The motor is cooled by natural convection, so it does not require an external blower or liquid circuit. Its housing uses the standard MSK footprint, which helps it fit typical machine layouts based on this motor family. Cable routing is simplified by an encoder connector that is rotatable through 240°, allowing the outlet direction to be adjusted around guards, brackets, or other nearby components. Position data is transmitted over the Hiperface interface, and the encoder provides 128 signal periods per revolution for accurate feedback to the drive. The feedback system uses optical scanning, and the multiturn absolute encoder retains position information over multiple shaft turns so the controller can recover the true shaft angle after power cycling without a homing move.
An integrated electrically released holding brake secures the shaft when power is removed. The brake is rated for 4 Nm of static torque, which helps hold a stopped axis in place when external motion must be prevented. Mechanical power is transmitted through a keyed shaft, giving positive torque transfer to couplings, pulleys, or similar driven elements. The motor has the B length code and frame size 040, keeping the package compact for confined machine modules. Its 0450 winding code matches the electrical characteristics to compatible drive electronics for stable speed and torque control across typical servo duty.
