Product Description:

The MSK071D-0300-NN-M1-UP0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and positioned within the MSK IndraDyn S Synchronous Motors series. This self-contained rotary actuator converts drive currents from compatible converters into accurately controlled mechanical motion, making it suitable for positioning axes, packaging machinery, and pick-and-place stations throughout industrial automation. Its integrated servo design supports responsive acceleration, steady speed regulation, and repeatable positioning in equipment that must cycle continuously without sacrificing motion accuracy.

Mechanically, the motor is classified in frame size 071 with a D length housing that balances inertia against torque density for midrange applications. Its windings follow code 0300, which gives the electrical profile expected by matching Rexroth drive controllers. Heat is released to ambient through natural convection, a passive cooling method that removes the need for forced airflow or liquid circuits and keeps the installation simple. The shaft uses a keyway so torque can be transmitted directly to pulleys or couplings without relying only on a friction fit. The unit follows the standard design option and is supplied without a holding brake, so any static load must be secured by the drive or by an external mechanical lock.

Position feedback relies on a Hiperface interface that exchanges absolute data between the servo drive and the integral encoder. The sensing element uses optical scanning and delivers 128 signal periods per revolution, while a multi-turn absolute system retains position information across power cycles. A rotatable 240° connector lets the encoder lead exit in the preferred direction, which helps reduce cable stress and makes routing easier in tight enclosures. This feedback arrangement gives the drive the rotor-angle data needed for commutation, smooth speed regulation, and stable position control during repeated machine cycles.
