Product Description:

The MSK071E-0450-NN-S1-UG0-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. This unit converts electrical energy from an IndraDrive inverter into regulated rotary motion with high dynamic stiffness, making it suitable for coordinated positioning tasks in conveyor gantries, printing machinery, and pick-and-place stations. Closed-loop operation over the entire speed range allows the axis to follow command profiles accurately while maintaining repeatability under variable mechanical loads. Its compact frame eases installation inside machine frames where space is limited.

The motor relies on natural convection for heat dissipation, so ambient airflow removes losses without external fans or liquid circuits. Its plain shaft geometry offers a smooth cylindrical output suitable for clamp, collet, or coupling interfaces that do not require a key. Frame size 071 sets the stator outside diameter and the IEC mounting pattern, while length code E indicates the longest magnetic stack in this frame, giving higher continuous torque than shorter variants. Drive feedback is exchanged through the Hiperface serial interface, which carries absolute position data and incremental signals over a compact hybrid cable. Winding code 0450 tailors phase resistance and inductance to drives that supply the correct current envelope.

A swiveling encoder connector that is rotatable through 240° lets the cable exit be oriented after installation, minimizing strain in tight cabinets. Position sensing is carried out by an optical measuring head that resolves 128 signal periods per mechanical revolution; internal interpolation then produces fine incremental counts for smooth velocity loops. Because the measuring system is single-turn, absolute position is retained over one revolution, and multi-turn tracking must be provided by the control when required. The motor is delivered without a holding brake, so static load retention must be supplied either by the drive or by external mechanical locking.
