Product Description:

The MSK070D-0300-NN-M3-UG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Designed to convert electrical power into precisely controlled rotary motion, this motor serves as the drive element in industrial robots, gantry axes, and material-handling modules where rapid positioning and high repeatability are required. Its compact frame and feedback-ready construction allow the unit to integrate directly with Rexroth drive controllers, supplying the mechanical torque needed in modern automation cells without requiring additional transmission stages or external couplings.

The motor housing is cooled by natural convection, so heat is dissipated through the surface without fans or external liquid circuits. The frame size is 070, and the D length code gives the motor a midsize footprint suited to medium torque ranges. The motor uses winding code 0300, which corresponds to the resistance and inductance values expected by the drive amplifier. For positional feedback, a rotatable 240° connector links the integrated capacitive encoder that communicates through the Hiperface protocol, and the multi-turn absolute format returns shaft angle and revolution count to the control loop. A sealed enclosure with an IP65 rating helps protect internal components from dust ingress and water jets.

The mechanical output uses a plain shaft, offering direct coupling to gearboxes or pulleys without keys. Because the unit is supplied without a holding brake, any static load must be secured by drive torque or an external clamp. The encoder provides 16 signal periods, which support smooth interpolation at the controller. The motor uses insulation class 155 and operates in ambient air between 0–40 °C, so separate cabinet cooling is usually unnecessary.
