Product Description:
The MSK040C-0450-NN-S2-UG0-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a dynamic drive element, this motor provides closed-loop torque and position control for pick-and-place axes, packaging machines, and other precision automation tasks that rely on rapid acceleration and repeatable positioning. The encoder connector can be rotated, which eases cable routing in confined enclosures.
The motor is cooled by natural convection, so heat is dissipated through its housing without fans or liquid circuits, simplifying cabinet design. Its housing carries a protection rating of IP65; dust ingress is prevented and the unit tolerates low-pressure water jets, allowing installation near process equipment. Position feedback is routed through an EnDat2.1 serial interface, giving the drive controller absolute position data and electronic nameplate information over a single cable. Inside the encoder, an optical disk yields 2048 signal periods, and the feedback system is a single-turn device, which reports absolute position for one mechanical revolution and suits axes that reference on startup without exceeding one turn during operation.
The 240° adjustable connector arc helps maintain sealing integrity when the cable entry must face upward or sideways. Continuous operation is specified for ambient temperatures from 0–40 °C, so no derating is required in a standard factory hall. A plain shaft transmits torque without keyways, favoring clamp couplings that minimize backlash. Thermal endurance comes from an insulation system rated at class 155, supporting winding temperatures up to 155 °C during peak duty cycles. The winding code 0450 matches this motor to MSK drive parameters, and the unit is delivered without a holding brake to suit applications that rely on mechanical clamps or drive torque for static load support.
