Product Description:
The MSK070D-0300-NN-M1-UG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a closed-loop rotary actuator, it converts drive current into precisely regulated torque and speed for positioning tasks in automated machinery and robotics. It interfaces directly with IndraDrive servo controllers, closing high-bandwidth motion loops on packaging lines, pick-and-place gantries, and test rigs. This operating role suits axes that need repeatable starts, stops, and direction changes rather than simple constant-speed rotation. It is well suited to applications where the controller must correct position error continuously under changing load conditions.
This motor rejects heat through natural convection, so installation must allow free airflow around the housing. Position feedback is supplied via a Hiperface interface, and this digital bus carries absolute and incremental data from the integrated optical encoder. That encoder resolves the shaft angle into 128 signal periods, and because it is a multiturn absolute device, it retains position information across power cycles. The underlying scanning method is optical, which supports accurate commutation and stable speed regulation during low-speed and dynamic operation. Because the feedback channel combines position and incremental information, the drive can maintain smooth servo behavior during indexing, contouring, and reversal.
The output side uses a plain shaft, eliminating keyway stress concentrations in couplings. Frame code 070 corresponds to the stator diameter and mounting pattern, while winding code 0300 matches the electrical characteristics expected by compatible MSK drive modules. The unit is supplied without a holding brake, so static load retention must be achieved by the external drive or machine mechanics. A rotatable 240° connector on the encoder side simplifies cable routing where installation space is limited. The rotatable connector can also help keep the feedback cable away from moving machine members and nearby power wiring. The motor body uses housing length D, which helps the unit fit compact axis layouts without changing the frame diameter.
