Product Description:

Bosch Rexroth Indramat manufactures the MSK070E-0450-NN-S1-UG1-NNNN as part of the MSK IndraDyn S Synchronous Motors series. This servo motor converts controlled electrical input into precise rotary torque for positioning axes, packaging equipment, and other closed-loop automation where repeatable movement and compact installation space are important. When paired with a compatible drive controller, it supports stable speed regulation and repeatable positioning during frequent start-stop cycles. The compact housing suits machines that need precise motion in limited mounting space.

The integrated holding brake supplies 23 Nm of static torque and is electrically released, so the shaft remains locked whenever control power is removed. Heat is removed by natural convection, eliminating the need for external blowers or coolant circuits. An enclosure rating of IP65 shields the stator and connectors against dust ingress and low-pressure water jets, enabling mounting near the work zone. Motion feedback is delivered through a Hiperface optical encoder that provides 128 signal periods per revolution, allowing the drive to derive high-resolution position data for smooth velocity loops. The encoder plug can be rotated by 240 degrees to simplify cable routing in tight machines and to reduce cable strain around the motor body.

The motor uses a plain shaft to transmit torque without a keyway, which helps minimize runout when coupled to precision gearheads. This arrangement also supports smooth rotation in precision servo applications. The encoder is a single-turn design, so it measures absolute position within one mechanical revolution. Continuous operation is permitted from 0 to 40 °C. Winding code 0450 identifies the electrical layout used for this motor size, and insulation class 155 supports winding temperatures associated with cyclic duty.
