Product Description:

The MSK071E-0450-NN-S1-UG0-NSNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Intended for industrial automation, it converts drive-controller current into precisely regulated torque and speed for accurate positioning and velocity control on packaging, handling, and processing axes. It uses a high-resolution feedback system to maintain consistent closed-loop performance under variable mechanical loads. This supports repeatable motion on transfer units and indexing applications that require stable response during frequent starts and stops.

Heat generated by the stator is removed through natural convection, so the unit depends on ambient airflow rather than forced fans. The encoder plug is rotatable through 240°, allowing the cable exit to be aligned after mounting. Position feedback travels over a Hiperface serial link that carries both incremental and absolute data from an optical measuring head. Inside the encoder, the disk provides 128 signal periods per revolution, and the device is a single-turn type that reports an absolute position within one mechanical revolution. The motor uses winding code 0450, has motor size 071 with length E, supports standard operation and explosion-protected installation, and is built without a holding brake to keep axial length and inertia lower.

The housing carries an IP65 ingress-protection rating, so it resists dust and low-pressure water jets during routine cleaning. Thermal capability comes from insulation class 155, permitting continuous operation within an ambient range of 0 to 40 °C without accelerated winding aging. A plain shaft simplifies coupling to gearheads or belt pulleys and can reduce stress concentrations associated with keyed connections. The compact housing also helps the motor fit tightly spaced machine layouts where mounting access and cable routing space are limited.
