Product Description:

The MSK071C-0450-NN-S3-UP0-NNNN synchronous servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It serves as the rotary actuator in positioning and interpolation tasks, converting electrical power from an IndraDrive controller into precise shaft motion for machine tools, packaging lines, and assembly robots. A compact housing integrates power and feedback connectors, helping simplify installation in multi-axis systems.

The motor uses natural convection for cooling, so heat generated in the stator dissipates through the finned housing into the surrounding air without fans or liquid loops. Position and speed information are exchanged through the Hiperface protocol, which carries analog sine-cosine tracks and a digital memory channel for stored motor data. Inside the feedback assembly, the capacitive sensor disc is subdivided into 16 signal periods, which supports fine angular resolution for servo control. A cast-aluminum enclosure with an IP65 rating prevents dust entry and withstands low-pressure water jets, allowing the motor to be mounted outside sealed cabinets. Continuous duty is permitted at ambient temperatures from 0 to 40 °C, supporting stable torque production in typical indoor environments.

Mechanical integration is straightforward because torque is delivered through a shaft with a keyway, which is a common interface for couplings and belt drives. The unit is supplied without a holding brake, so loads must be secured by external means when braking torque is required at standstill. Electrical service is eased by a feedback connector that is rotatable by 240°, allowing the cable to be oriented toward the cabinet, floor, or ceiling without changing the strain relief. The windings use insulation class 155, which supports elevated internal temperatures during short load peaks. The motor has frame size 071, length code C, winding code 0450, and single-turn feedback in the standard housing design.
