Product Description:

The MSK070D-0450-NN-M2-UP1-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Within an automation cell, it couples to a drive controller to convert commanded current into precise shaft rotation, supporting coordinated motion in packaging, printing, and material-handling equipment. It is suited for servo axes that require repeatable positioning, smooth speed regulation, and rapid response to changing loads. The motor also supports continuous machine cycles in applications where accurate feedback and controlled torque must work together.

Heat is removed through natural convection, so cabinet layouts must allow free airflow around the housing. An IP65 protection rating shields the stator, connectors, and feedback head from dust and water jets commonly found on factory floors. Position data is exchanged over the EnDat 2.1 interface; this bidirectional link carries absolute position data and diagnostic information. Feedback accuracy depends on the optical scale’s 2048 signal periods, which the controller interpolates for finer resolution. The encoder plug can rotate through 240° to simplify cable routing in tight machines. The 070 frame size, D length, and winding code 0450 identify the motor’s basic size and electrical configuration.

An electrically released holding brake delivers 23 Nm of static torque, securing the load during power-off or emergency stops without separate clamps. Continuous service is permitted from 0–40 °C; outside this range, derating or external cooling is required. The windings use class 155 insulation, allowing higher permissible copper temperatures before thermal aging begins. Multiturn feedback is provided by multiturn absolute position sensing, so the drive can retain position information across multiple shaft revolutions. A shaft with keyway transfers torque into couplings or pulleys, and the increased concentricity helps limit vibration that could affect tool life or sensor readings.
