Product Description:

The MSK050B-0450-NN-S1-UG1-NNNN synchronous servo motor is built by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop motion axes in industrial automation where accurate torque and velocity control are needed for packaging, pick-and-place, and tooling stations. The motor converts drive commands into precise rotary motion, helping automated axes maintain position and respond quickly to changing loads. It is well suited to applications that require repeatable movement during frequent start-stop cycles.

Its cooling relies on natural convection, so heat is dispersed through the housing without external fans. The motor housing carries a protection class of IP65, which blocks dust ingress and low-pressure water jets and supports installation near washdown zones. An electrically released holding brake supplies 6 Nm of static torque, allowing vertical loads to remain stationary when power is removed. Position feedback is furnished by an optical encoder that provides 128 signal periods per mechanical revolution. Data and power for the feedback device travel through the Hiperface interface, and the encoder connector can be rotated through 240° to simplify cable routing in cramped enclosures.

The stator winding identified by code 0450 matches the electrical characteristics expected by compatible IndraDrive controllers, while the B lamination length supports continuous torque appropriate for size 050 frames. Class F insulation rated to 155 °C helps protect the winding from thermal aging during sustained operation. The motor uses a plain shaft for torque transmission without keys, which helps support precise coupling alignment. It has single-turn feedback rather than multi-turn counting, so applications with home switches can establish a reference position without additional turns data. Safe operation is limited to ambient conditions from 0 to 40 °C, and operation above that range requires derating.
