Product Description:

Bosch Rexroth Indramat manufactures the MSK070D-0300-NN-S1-AG0-NNAN as part of the MSK IndraDyn S Synchronous Motors series. This synchronous servomotor is built for closed-loop motion axes in industrial automation, providing precise torque and speed control to machinery such as packaging stations and handling gantries. It is suitable for applications that require repeatable positioning and stable speed regulation during frequent start-stop cycles. That makes it a practical choice for feeders, indexers, and transfer units that must respond quickly to changing load conditions.

The motor frame follows size 070, giving a flange pattern suitable for medium-torque duties. Length class D increases active stack height for higher continuous output without enlarging the mounting footprint. Winding code 0300 identifies the electrical winding used for matching drive operation. Heat is dissipated by natural convection, a passive method that keeps the housing temperature within limits when airflow is available. The motor has reduced run-out, which indicates tighter shaft concentricity for smoother coupling with precision gearboxes. The shaft is a plain version for clamp or collet connections, and the power connector is positioned on the A-side to simplify cable routing inside narrow machine frames. The unit comes without a holding brake, so position retention during power-off must be handled by the drive or an external locking device.

The feedback system uses Hiperface communication to link the motor with compatible IndraDrive controllers. An internal optical scanning element generates 128 signal periods, supporting fine velocity control with minimal quantization error. Because it is a single-turn encoder, the drive resolves absolute position over one mechanical revolution and relies on external homing for travel beyond that range. The encoder data lets the controller correct small speed deviations quickly and maintain smooth motion at low and moderate speeds. It is useful on coordinated axes that must start, stop, and reverse without unstable feedback behavior.
