Product Description:

The MSK040C-0450-NN-S3-UP1-NNNN is a servomotor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is an IndraDyn S synchronous servomotor intended to supply precise torque and position control to automated axes, pick-and-place modules, and other motion sequences in industrial machinery. By integrating a keyed shaft and an electrically released holding brake, the unit can provide secure mechanical coupling and maintain load position when drive power is interrupted. This arrangement is useful on vertical or indexing axes where controlled stopping and repeatable restarting are important during normal machine operation.

Heat is removed only by natural convection, a cooling method that simplifies installation because it does not require forced airflow or liquid circuits. The motor housing carries a protection rating of IP65, so dust is kept out and low-pressure water jets cannot reach internal components. The motor has size code 040 and length code C, giving it a compact geometry for machines with limited mounting space, while winding code 0450 suits medium-torque duty cycles. A shaft with keyway eases coupling to gearheads or pulleys, and the electrically released brake provides 4 Nm of static torque to hold the axis at standstill. Position feedback is exchanged with the drive over the Hiperface interface, and its sensing element uses capacitive measurement for resistance to magnetic stray fields.

The encoder resolves rotor angle into 16 signal periods per mechanical revolution, giving the drive the feedback information needed for stable commutation and controlled positioning. Its rotatable connector can be oriented through 240°, which helps route cables cleanly in tight enclosures and around nearby machine members. With an ambient operating window of 0–40 °C, the motor is intended for standard industrial conditions. The insulation system is rated to class 155, which supports thermal durability during continuous operation. These operating characteristics make the motor suitable for compact servo axes that require accurate motion, protected housing, and straightforward cable routing.
