Product Description:

The MSK070D-0450-NN-S2-UG1-RNNN servomotor is produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It converts drive-controller output into tightly regulated rotary motion for packaging, printing, and material-handling axes in industrial automation. By supplying precise position and velocity feedback through an integrated encoder, the unit enables closed-loop control of dynamic loads in multi-axis machinery. This makes it suitable for applications that require repeatable acceleration, deceleration, and holding behavior during frequent cycle changes.

The motor is cooled by natural convection, so no external fan is required and thermal performance depends on ambient airflow around the housing. Winding code 0450 corresponds to the electrical characteristics used with the MSK drive family, while Class 155 insulation supports continuous winding temperatures up to 155 °C. Position data come from an optical encoder that uses an EnDat2.1 digital interface with 2048 signal periods of incremental resolution. This data stream supports commutation, speed regulation, and alarm diagnostics inside the controller. Because the measuring system is single-turn, one absolute angle is available per revolution, and applications that rotate beyond 360° require a reference cycle after power-up.

Mechanical integration is aided by the electrically released holding brake, which supplies 23 Nm of static torque to secure vertical or indexing loads when power is removed. The drive end carries a plain shaft that is machined for low runout in line with the increased concentricity design, and the housing has an IP65 rating that resists dust and water jets during washdown cycles. Connections exit through a rotatable 240° encoder plug, which helps route cables around adjacent machine components with less strain at the connector. The D length variant of the Size 070 frame adds active iron while keeping rotor inertia moderate. Operation is permitted from 0–40 °C, which matches typical control-cabinet and machine-area conditions.
