Product Description:

Bosch Rexroth Indramat manufactures the MSK071D-0300-NN-M1-UG2-NNNN, a component of the MSK IndraDyn S Synchronous Motors series. The unit is an IndraDyn S synchronous servomotor that converts electrical power into tightly regulated mechanical rotation for industrial automation tasks such as pick-and-place robots, indexing tables, and feed drives. By combining high-resolution feedback with a compact mechanical build, it helps controllers hold commanded positions, follow velocity profiles, and apply consistent torque under changing loads. It is suited to motion systems that need repeatable axis control in a compact installation space.

The motor requires Cooling FN, so continuous duty assumes free airflow around the housing. Under these conditions it relies on natural convection rather than forced air or liquid cooling, so the installation needs clearance for heat dissipation. The motor has a standard design with no special coatings or shortened frame. Position feedback is handled by an optical encoder that communicates through the Hiperface serial interface, and the plug can be rotated 240° to simplify cable routing. That adjustable connector position helps when the motor is mounted in tight machine spaces. Inside the encoder, 128 signal periods per revolution form the base incremental track for fine interpolation.

The encoder also stores up to 4096 turns and reports position as multiturn absolute data, so the axis can retain position information after shutdowns. An electrically released brake provides 30 Nm of holding torque for vertical axes or controlled stops. The motor uses a plain shaft, allowing couplings or pulleys to be mounted without keyways. Frame code 071 identifies the stator size, while winding code 0300 corresponds to the electrical values expected by the matching drive. Length class D indicates the longer housing in this frame size, which provides more active stack length for the motor.
