Product Description:
The MSK040B-0450-NN-M2-UG0-NNNN synchronous servo motor is produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In industrial automation, this compact motor couples directly to a driven load and delivers precise torque and velocity so that conveyors, actuators, and tooling heads follow the trajectories commanded by an electronic drive controller. Its compact format also suits machine axes where accurate positioning and stable speed control are required. It can be used where fast response and repeatable motion are needed across short machine cycles.
With its standard mechanical design, the unit relies on natural convection to remove heat, eliminating the need for external fans in cabinets where airflow is limited. The B active length, combined with the size 040 stator frame, creates a narrow profile that helps simplify multi-axis arrangements. Motion feedback is handled through the EnDat2.1 serial interface, and the optical sensor delivers 2048 signal periods per revolution for fine resolution in high-gain control loops. Housing joints, cable glands, and the terminal area meet the IP65 ingress rating, helping keep out dust and water jets during washdown cycles. Reliable operation is permitted in ambient conditions from 0 to 40 °C, allowing the motor to share space with nearby control electronics without derating.
The motor uses a multi-turn absolute encoder, so axis position is retained over 4096 mechanical turns even after power is removed. Its connector can be rotated through 240° to simplify cable routing, and the optical scanning principle helps minimize signal drift over time. A plain shaft transmits torque without keyways when paired with clamp couplings, and the motor does not include a holding brake, so vertical axes require an external locking method. Class 155 insulation supports the continuous copper temperatures associated with winding code 0450, which matches the electrical characteristics expected by a compatible drive.
