Product Description:
The MSK070D-0450-NN-M2-UG1-RNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This brushless AC unit converts commanded current into tightly regulated torque and speed, making it a core actuator for packaging lines, pick-and-place gantries, and forming presses. Its synchronous design supports frequent starts, stops, and speed changes in automated machinery. By integrating high-resolution feedback and an internal brake, the motor serves as a direct-drive element in automation cells that demand repeatable positioning without external gearing.
The MSK070D model relies on natural convection for heat dissipation, so installations must provide free airflow around the stator housing. This cooling method avoids the need for an auxiliary fan on the motor housing. Positional data is delivered over the digital EnDat2.1 link and is derived from the encoder’s 2048 signal periods per electrical revolution. Because the feedback system remembers shaft angle after power loss, the multi-turn absolute capability eliminates homing routines after startup. An electrically released brake supplies 23 Nm of static torque to lock vertical axes during downtime. The 070 frame and D-length lamination stack are matched to a tailored winding group that supports medium continuous currents without excessive temperature rise.
The motor uses increased concentricity to limit mechanical runout, which benefits applications that couple directly to precision spindles. Accurate position sensing is reinforced by the optical scanning method inside the encoder, which is resistant to magnetic interference. A plain shaft simplifies coupling with compression hubs, and the rotatable 240° connector lets the feedback cable exit in a convenient direction to avoid tight bends. The rotatable connector is useful when adjacent machine members leave limited room behind the motor. The motor uses winding code 0450, which matches the electrical characteristics expected by the drive.
