Product Description:

The MSK070C-0450-NN-S3-UG1-NNNN is a synchronous servo motor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop positioning and speed control in automated production lines, pick-and-place modules, and packaging axes where accurate motion and repeatable response are required. The motor can be coupled directly to an IndraDrive controller, which supports responsive axis control without requiring additional gearing in many applications. With a 070 frame size and C-length stator, it fits medium-power machine stations that need a compact motor with solid torque density.

The housing has an IP65 protection rating, which helps keep out dust and water jets during operation near the machine. Cooling is provided by natural convection, so the motor does not require a separate fan or liquid cooling circuit. Feedback is handled by a Hiperface capacitive encoder, and the connector can rotate 240 degrees to make cable routing easier in tight installations. Inside the encoder, 16 signal periods per revolution are used for interpolated position data and smooth speed feedback. An electrically released holding brake provides 23 Nm of static torque to hold vertical axes when power is removed.

The stator uses Class 155 insulation, which supports continuous operation when the ambient temperature remains within 0 to 40 °C. Torque is transmitted through a plain shaft, allowing the motor to be connected with clamp hubs or other suitable coupling elements. The encoder is a single-turn device, so it provides absolute position information within one mechanical revolution and suits rotary axes that perform a homing routine after startup. The electrical setup is matched to winding code 0450, which corresponds to the voltage and current characteristics used for the intended speed-torque profile. The motor also follows the standard mechanical layout used across this platform, which supports compatibility with common IndraDyn S mounting interfaces.
