Product Description:
The MSK070D-0300-NN-S2-UP0-RNNN is produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As an AC servo motor, it converts inverter-generated current into controlled mechanical motion for positioning tables, pick-and-place arms, and other closed-loop automation axes. The device integrates a permanent-magnet rotor, an optical feedback system, and a keyed output shaft so that drive controllers can command repeatable torque and velocity without external sensors. This arrangement supports accurate speed changes and stable position tracking during repeated machine cycles.
Heat is removed through natural convection, so installation must allow free airflow around the housing. The housing is sealed to IP65, which blocks dust and low-pressure water jets in typical machine enclosures. The feedback housing carries a connector that is rotatable through 240°, which eases cable routing when space behind the motor is limited and helps reduce cable strain in tight layouts. Position data are transmitted over the EnDat2.1 serial interface, permitting digital diagnostics and automatic parameter download at power-up. Inside the encoder, the disk generates 2048 signal periods per revolution, delivering fine angular resolution to the controller for smooth velocity regulation.
The measuring principle is optical, which provides high repeatability and low interpolation error for contouring tasks. A single-turn code track is implemented, so absolute position is retained within one mechanical revolution, and external homing is required if multi-turn data are needed. Continuous service is permitted from 0 to 40 °C, matching most control cabinet environments without derating. The winding insulation is rated at Class 155, allowing the stator to operate within F-class temperature limits. The design also uses increased concentricity to reduce runout at the keyed shaft during precise motion. The D-length 070 frame uses winding code 0300 for the intended torque constant, and a holding brake is not fitted, so any load-side locking must be provided by the machine when power is removed.
