Product Description:

The MSK040C-0450-NN-S3-UP0-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It converts drive current into tightly controlled torque and speed for automated assembly cells, gantry loaders, and secondary packaging stations. When paired with an IndraDrive amplifier, the motor supports repeatable positioning and stable motion during frequent start-stop cycles. It is intended for servo-controlled machinery that depends on consistent acceleration and deceleration. Its compact form suits machine axes that need accurate response without adding unnecessary moving mass.

Cooling is done by natural convection, so heat leaves the housing through surface radiation and ambient airflow without fans. An enclosure rating of IP65 blocks dust ingress and low-pressure water jets, allowing mounting close to the motion axis without a separate protective cabinet. Position data comes from a capacitive encoder that communicates over the Hiperface protocol; its feedback disk provides 16 signal periods per mechanical revolution and reports absolute angle within a single-turn range. The connector can rotate 240° to simplify cable routing, and the motor is supplied without a holding brake, so vertical loads require external holding force when power is removed.

The standard stator design uses winding code 0450 and the compact C length within the 040 frame, giving a favorable torque-to-mass ratio for lightweight machine axes. The insulation system is class 155 and remains stable in ambient temperatures from 0–40 °C during continuous operation. Mechanical power is transferred through a shaft with keyway, which provides a positive connection for pulleys, couplings, or gearheads. This shaft style is useful where slip between the motor and the driven load must be avoided.
