Product Description:

The MSK070D-0300-NN-S1-UP1-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Designed as a feedback-controlled rotary actuator, it couples with IndraDrive controllers to position machine axes in packaging, printing, and material-handling equipment. By converting electrical energy into precise torque and speed, the unit supports closed-loop automation where accuracy and repeatability are essential. It is commonly used on indexing, feed, and transfer axes that need predictable motion over repeated production cycles.

This motor relies on natural convection cooling, so heat is dissipated directly through the housing without forced airflow. An electrically released holding brake delivers 23 Nm of static torque, keeping vertical or load-bearing axes fixed when power is removed. Position data is generated by an optical single-turn encoder that provides 128 signal periods, giving the drive controller granular feedback for fine velocity regulation. Communication between the encoder and controller passes through the Hiperface interface, which carries both incremental and absolute data on the same cable. Mechanical power is transferred through a shaft with a keyway, allowing positive locking to pulleys or couplings and reducing the chance of slip under cyclical loads.

The motor’s geometry aligns with the series naming, where size code 070 corresponds to the stator diameter and length code D indicates an extended stack for higher continuous torque capacity. Electrical behavior is matched to drive ratings by winding code 0300, which corresponds to the resistance and inductance values expected by IndraDrive amplifiers. Field wiring is simplified because the encoder connector can be oriented through 240°, letting cables be routed toward the cabinet with less bending strain. This adjustable connector position can make cable routing easier when the motor is installed in compact machine frames or near adjacent axes.
