MSK071D-0450-NN-M2-UP1-RNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK071D-0450-NN-M2-UP1-RNNN from the MSK IndraDyn S Synchronous Motors series is a permanent magnet synchronous servomotor featuring an increased concentricity design and a shaft with keyway. It delivers a continuous torque at standstill (100 K) of 20.0 Nm with 17.6 A continuous current and reaches a maximum torque of 66.0 Nm at 69.3 A. The motor employs optical Encoder Technology with an EnDat2.1 interface, 2048 signal periods Encoder Resolution and a rotatable 240° Encoder Connector, supporting multiturn absolute position recording. Its natural convection Cooling and electrically released holding brake with 23 Nm Holding Brake Torque ensure reliable operation. With a winding inductivity of 3,200 mH, motor size 071 and length D, this IndraDyn S servomotor is designed exclusively for use with the manufacturer’s drive controller.

Frequently Asked Questions
How does natural convection cooling affect the motor’s installation requirements?
The motor relies on ambient airflow to dissipate heat so it requires sufficient clearance around it. The absence of forced cooling makes it suitable for quiet environments with moderate duty cycles.
What is the advantage of using a multiturn absolute encoder in this servomotor?
The encoder can track position across multiple revolutions without external reference. The feature ensures reliable positioning in applications where homing cycles are undesirable.
How does the increased concentricity design benefit mechanical performance?
The design improves shaft alignment which minimizes vibration and enhances coupling accuracy. The result is smoother torque transfer in precision machinery.
Why is the electrically released holding brake important in motion control applications?
The brake engages when power is removed which ensures the load is safely held in position. The feature is critical in vertical axis systems where unplanned motion could cause safety issues.
How does the winding inductivity value influence drive performance?
The inductivity smooths current flow which improves stability during dynamic operations. The property also reduces torque ripple at varying speeds.
