Product Description:
The MSK071E-0450-NN-M2-UG0-RNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is used in automated machinery to supply closed-loop torque, speed, and position control through its internal encoder and sinusoidal commutation. This makes it suitable for precision axes that need repeatable motion during indexing, feeding, and positioning tasks. It fits packaging, handling, and transfer equipment that depends on fast response and stable servo behavior. Size 071 with length code E gives the motor a compact frame, and the encoder connector can be rotated 240° to simplify cable routing in tight control cabinets.
Heat is removed by natural convection, so the housing conducts thermal energy away from the stator without additional blowers. The feedback system uses optical scanning and communicates with the drive over the EnDat 2.1 digital interface, so the control system receives position data in digital form. Within this protocol, the encoder provides 2048 signal periods, giving high angular resolution for precise servo loops. The enclosure is rated IP65, which protects the motor and connectors against dust ingress and low-pressure water jets during normal washdown. The rotor shaft is machined for increased concentricity, and winding code 0450 identifies the electrical resistance and inductance values used by matching IndraDrive controllers.
The motor has a plain shaft without a keyway, so zero-backlash couplings can be clamped directly to the journal. Position data remain valid after power loss because the encoder is a multiturn absolute encoder that tracks revolutions mechanically. Operation is specified from 0 to 40 °C, allowing cabinet or open-machine mounting without special cooling provisions. Insulation class 155 supports elevated winding temperatures before thermal aging accelerates. The unit is supplied without a holding brake, so static torque must be provided by the drive or by an external clamp when the axis must remain fixed at a standstill.
