Product Description:

The MSK071E-0300-NN-S1-UG0-NPNN belongs to the MSK IndraDyn S Synchronous Motors series produced by Bosch Rexroth Indramat. This servo motor is intended for closed-loop positioning and velocity control in automated assembly cells, packaging lines, and related industrial platforms. By coupling directly to gearboxes or load shafts, it delivers repeatable torque and speed that can be synchronized with compatible drive controllers for coordinated machine motion. The design suits machines that require accurate starts, stops, and speed changes across repeated duty cycles.

The motor uses natural convection to transfer heat from its stator housing, so no external fan or liquid circuit is required when ambient airflow is available. Mechanical integration uses a B5 flange assembly with a centering shoulder that seats against the machine frame and positions the shaft for coaxial load attachment. Service wiring benefits from the rotatable 240° connector, allowing the feedback plug to be oriented away from nearby obstacles after installation. Position data leave the motor over the Hiperface serial channel, and the feedback disk supplies 128 signal periods per mechanical revolution. The E-length stator and 0300 winding code set the torque and current characteristics for medium-duty axis service.

The encoder’s sensing element is optical, so incremental and absolute tracks are read without contact, which reduces wear in high-cycle applications. Because the device is single-turn, it reports absolute rotor position within one revolution, while additional turn tracking can be handled by the control system when required. The motor is supplied without a holding brake, so vertical or suspended loads need external holding force when power is removed. Its frame conforms to motor size 071, giving it an outside diameter suited to compact packaging and material-handling equipment where installation space is limited.
