Product Description:

The MSK070D-0300-NN-S1-UP1-NSNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is used where closed-loop control of position and velocity is required in industrial automation cells such as pick-and-place modules, indexing tables, and other servo-driven machine axes. When paired with a compatible drive controller, the motor converts commanded current into precise rotary motion for repeatable positioning and stable speed regulation. Its compact stator design and keyed shaft help transmit torque to gearboxes or precision couplings with low backlash during frequent start-stop cycles.

The motor has size 070 and length D, which gives it a longer active stack within this frame for higher continuous torque. Cooling is handled by natural convection, so no external blower is required and the installation stays mechanically simple. The housing is sealed to IP65, which helps protect internal components from dust and low-pressure water jets in typical industrial areas. An electrically released holding brake provides 23 Nm of torque for axes that must remain in position at standstill, and the keyed shaft supports secure torque transfer to the driven mechanism.

Feedback is provided by a Hiperface encoder with 128 signal periods per revolution and single-turn optical scanning, giving the drive accurate rotor position data for commutation and speed control. The connector can rotate 240 degrees, which helps with cable routing in tight machine spaces and reduces strain at the housing entry. Continuous operation is supported from 0–40 °C, and insulation class 155 allows the winding system to tolerate elevated internal temperatures during normal servo duty. The rotating connector is useful where motor cables must clear guards, machine frames, or adjacent axes.
