Product Description:

The MSK070C-0300-NN-M2-UP1-RSNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop motion axes where precise torque delivery and position feedback are required in automated machinery. By integrating a multi-turn optical encoder and a keyed shaft, the unit converts electrical drive commands into rotational motion suitable for packaging lines, pick-and-place systems, and general factory automation. That combination allows the paired drive to regulate speed and position with feedback provided directly from the motor.

The motor uses natural convection for cooling, so no external blower or liquid circuit is necessary, which helps simplify cabinet layout. A permanently attached holding brake supplies 23 Nm of torque, and because it is electrically released, the axis remains locked whenever power is off. The housing carries a protection rating of IP65, keeping dust and low-pressure water away from internal components and allowing mounting outside sealed enclosures. Winding code 0300 identifies the electrical characteristics used for this length-C, size-070 stator and matches the motor with compatible IndraDrive amplifiers. Insulation class 155 permits continuous winding temperatures up to 155 °C, providing thermal headroom for cyclic duty within a 0 to 40 °C ambient range.

Position data are transmitted through the EnDat2.1 bidirectional serial interface, enabling automatic parameter transfer to the drive and high-resolution feedback. Inside the encoder, a glass scale generates 2048 signal periods per revolution, and its multi-turn absolute design retains turn information after power loss. The encoder connector is rotatable through 240°, so cable exit direction can be adjusted without placing unnecessary strain on the leads in tight electrical cabinets. Optical scanning supports accurate feedback, and the keyed shaft provides positive torque transmission to the driven load.
